Projects of country houses on the slopes, irregularities, hills. Construction of the remaining stages. Plot with a slope: what to look for

The construction of a house on a site with a slope is associated with a lot of difficulties and increased financial costs. But having overcome the problems that arise, as a result, you can get an original structure that will not only be functional and cozy residential building, but also stand out with non-standard design solutions.

Choosing a project for building on a slope

Like any other construction, the construction of a residential cottage on a slope site begins with a plan.

It is best to apply for such a service to specialized companies, because a typical project in this case will not work. Architects and designers will analyze the shape of the site, and create plans for the building, in accordance with the terrain.

The angle of inclination of the land plot has a digital value, is calculated according to a certain formula, and is measured as a percentage. For example, if the allotment has a length of 100 meters and, at the same time, its vertical rise is 10 m, then its slope is 10%.

There is a certain gradation of the unevenness of the sections, depending on the magnitude of the angle:

  • until 3%- such areas are considered flat;
  • up to 8%- small slope;
  • up to 20%- average;
  • over 20%- steep slope

Main headache builder - how to properly design and build a house on medium and steep sites. For a flat area, you can easily pick up almost any type of project you like. What can not be said if the land is on a slope - if a hill "crashes" into your house, here, whatever one may say, you will have to order / develop an individual one.

Two types of houses are built on medium and steep slopes:

  1. Stepped- each floor / section of the cottage is arranged in levels (one above the other), in accordance with the slope of the earth, and has its own roof. Such buildings are:
  2. Cascade-sectional– suitable for land with a slope angle of up to 20%;
  3. Terraced- erected on land plots with a slope of more than 20%;
  4. Houses of variable number of storeys- in this case, the entire area of ​​​​the premises is under one common roof, but the number of floors may vary, depending on the terrain.

We design an entrance

When developing a project, it is necessary to take into account on which side the entrance for cars will be? If from the top of the slope, then the house must be planned accordingly. From the street, such a building will seem insignificant, and only by going inside, it will be possible to assess the true size of the mansion.

If the access road runs along the lower boundary of the site, then the buildings located on it will be fully visible from the road, because visually the site with the buildings will go down the slope. This means the layout of the building, and households. buildings need to be correlated taking into account not only the convenience of access roads, but also security and privacy.

Focusing on the world

Experts advise to pay attention also to the orientation of the house on the slope relative to the cardinal points.

Building a house on the east and south side, which is warmer by the sun and protected from cold winds, will save on heating.

Features of the arrangement of the foundation on a site with a slope

Mandatory steps, before starting construction on difficult terrain, are geodetic measurements. They allow you to accurately determine the degree of slope. In parallel, hydrogeological surveys are being carried out aimed at identifying the level of groundwater occurrence and determining the composition of the soil at the site.

Based on the results of these studies, will be selected best option foundation that can withstand the expected load.

It is not worth saving on these works, because mistakes made when laying the foundation of a building can lead to its deformation, partial or even complete destruction.

What types of foundations are suitable for uneven areas?

Even on a flat area of ​​​​the earth, special attention is paid to the arrangement of the foundation. After all, the durability of the house depends to a large extent on its strength and reliability. On sites with a slope, three types of foundations are used:

  1. Tape;
  2. stepped;
  3. pile.

Let us examine in more detail the features of each of them.

Strip foundation

The tape type is used on land plots with a slight slope. In areas with an inclination angle of more than 20%, arranging this type of foundation becomes economically impractical only if you plan to build a basement.

Horizontal level of the upper plane strip foundation must be perfect. A mandatory step is reinforcement, which will give the base the necessary strength.

Soils that are not prone to seasonal freezing (heaving) and waterlogging are suitable for pouring. If necessary, a small slope is leveled by pouring and ramming it to the required level.

stepped foundation

A variation of the tape is a stepped foundation. It is advisable to use it in areas with a sufficiently large height difference.

In this case, before pouring concrete, terraces are arranged, equal in area to parts of the house. A trench is dug at each site, formwork is mounted and reinforced.

Parts of the base are interconnected by jumpers or retaining walls. The total slope angle of the stepped foundation must match the slope angle of the soil layer with bearing capacity.

pile foundation

The pile type of foundation is the most common type used in the construction of houses on sloping plots. Here, retaining columns are used for construction.

The most popular solution is blocking screw piles, followed by the creation of jumpers between them. This type has a number of advantages:

  • It can be installed on heaving and mobile soils, because the piles are driven in well below the freezing level;
  • Suitable for areas with a wide variety of slope angles;
  • If structurally necessary, a combination with other types of foundation is possible.

Yes, and in most cases (unless a significant deepening of the piles is required), such a foundation for a house is much cheaper than other options.

A properly calculated and erected foundation will last for many years, without loss of strength, withstanding the effects of ground pressure and precipitation.

Therefore, when choosing and laying the foundation, it is worth listening to the recommendations of specialists and not saving on materials. Thrift in this case can significantly reduce the strength of the building and lead to other troubles during the operation of the house.

What should be considered when building a house on a land plot with a slope?

A sloping site will require a more thorough approach to planning the placement of a residential building and buildings. It is very important to correctly make the correct calculations of the depth of the foundation, as well as the distribution of the load on it:

1. Temperature changes

Night cold air always descends down the slope, and therefore a house erected in the lower part of the site will be in the path of its natural movement.

As a result, a "cold pocket" is formed. The temperature in it is several degrees lower than around, which is unacceptable for a residential building.

2. Water flows

The lower part of the slope (lowland) can often be flooded and even swamped, due to the accumulation of precipitation, and this negatively affects the structure.

For a cottage built on the highest point of the site, the problem of drainage is so great. In this case, using the features of the relief, it is possible to organize a natural runoff of surface waters.

Particular attention must be paid to waterproofing and drainage. After all, rain and melt water, flowing down an inclined surface, can wash away the foundation or even destroy it. It is possible to direct drains away from the building with the help of well-organized storm and drainage systems.

3. Soil movement and landslides

Before you start building on a site with a slope, it is recommended to carry out geodetic surveys.

If there is even the slightest hint of possible ground instability and soil movement, it is impossible to build on such a slope without strengthening. With a small slope, it will be enough to plant trees and shrubs, which hold the soil with their roots. But with a strong elevation difference, it is better to strengthen the soil with geogrids and piles.

Prior to construction, the land must be protected from landslides. For this, temporary retaining walls, piles, poles are built, driven into the ground in places most prone to displacement.

4. Entrance and location of special equipment

The organization of a construction site in such areas can be a problem. After all, you need a flat area for unloading building materials. Yes, and construction equipment on an inclined surface is not very convenient to work.

These issues should be taken care of in advance: prepare a flat horizontal place for unloading and temporary storage building materials, organize access roads.

There is an opinion that in order to construction works it is better to cut the slope and build on a flat area. This is fundamentally wrong. This method will disrupt the natural structure of the relief, which can lead to a change in the natural water horizon, and this is fraught with landslides. Yes, and it is extremely difficult to obtain permission from the administration to carry out such work.

conclusions

Building on a site with a slope has a number of undeniable advantages. This mainly concerns the visual component, because a multi-level house, on a hill, with a terrace, with several exits, looks much more interesting than housing built on flat land.

However, it should be noted that the construction of a cottage on an uneven site is fraught with a number of difficulties, and in order to solve them, the solution of which will take money. Saving money on the project, preparation of the territory, soil research is not advisable and, in some cases, even dangerous. The better these works are carried out, the foundation is laid, other parts of the project are implemented, the longer the house will please with warmth and comfort.

A plot of land with a difficult terrain is considered by many owners as a punishment. But any disadvantage can be easily turned into a virtue. To do this, you do not need to call the grader for alignment. A well-played height difference will demonstrate all the charm of a non-standard landscape. Of course, construction on a relief site, as well as its arrangement, will be fraught with difficulties. But the end result will give satisfaction with the work done and envy the neighbors. The article will focus on the proper arrangement of a site with a slope.

Attaching a house to a plot with a slope

There are 2 ways to link a building to a sloping site - without changing and with changing the existing landscape. A typical project is being developed based on the fact that the construction will be carried out on a flat site.

A house under construction in an area with natural conditions requires processing of the underground and basement parts. Thus, housing will have characteristic features that correspond to the site.

The slopes of the site are divided into:

  • on the plains, where the slope is up to 3%;
  • with a small slope (up to 8%);
  • with an average slope (up to 20%);
  • steep (over 20%).

On the slopes, not only the construction of buildings is difficult, but also the construction of access roads. Retaining walls, embankments and other reinforcing structures are installed on slopes with a height difference of 1:2.

slope project

Vertical layout of the site with a slope

Work on arranging a landscape with a complex "character" includes:

  • the maximum possible leveling of the relief, by removing the soil in one place and adding it in another;
  • organization of storm drains, which can be both hidden and open;
  • determination of the optimal location of the main house, gazebo, summer shower, vegetable garden, garden trees;
  • correction of small irregularities, using the terracing method, with steep drops - arrangement of retaining walls.

  • This approach will help not only to correctly divide the territory into functional zones, but also makes it possible to design it in an original way.

Drainage system on a site with a slope

  • The organization of the drainage system should be given due attention. Drainage will allow you to regulate the water balance, provide a quick drainage of water formed after precipitation or snow melt.
  • Rain and melt water form gullies. And the steeper the elevation difference, the greater the likelihood of slope failure. Since even small streams can create large ravines, lead to landslides of soil masses.
  • The arrangement of the drain is started after all the main earthworks and laying communications. Knowing at least the approximate location of the main buildings, green plantings will help to properly stretch the drainage system.
  • The laying method can be open or closed. Main advantage hidden system retraction is space saving. Since the channels run underground, access roads and paths can be arranged on top of them.
  • Trenches are dug along the slope of the entire territory of the site to the receiving collector. Efficiency is distinguished by laying drainage in the form of a "Christmas tree", where additional outlets at an acute angle adjoin the main line. With this method, the central trench should be just below the auxiliary channels.

  • The depth of the trenches can be from 30 cm to 1 meter. The slope should not be less than 2 mm per linear meter of length. This parameter is important even in areas with a slope, because part of the system can also pass through a flat area.
  • At the bottom of the trench, a 10 cm layer of sand is filled up and rammed. Geotextile is laid on top of it, the edges of which should cover the walls of the channel with a margin. Next, crushed stone is poured, with a layer thickness of 10-20 cm.
  • Perforated polymer pipes are laid on the gravel pad, and they are connected. The pipes are covered with a layer of crushed stone, and the finished system is covered with geotextile. The entire "pie" is covered with sand and soil.

slope design

The development of a complex landscape is associated with certain difficulties. But this should not be an obstacle. A competent approach to landscaping will lead to an enchanting result.

Plot with a slope photo

  • Height differences make it possible to embody the most daring, original ideas. Alpine design is best suited for these purposes. The highlight of this style is the use of roughly hewn stones and a large number of soft and bright colors. With the help of these 2 elements, the maximum tasks are solved:
    • zoning of the site is carried out;
    • boulders and plants serve as slope reinforcement;
    • contribute to snow retention;
    • beautifully decorate the whole space.
  • Planting green spaces should be carried out on the basis of the rule - the lower the point, the higher the plants. That is, low-growing varieties are planted on the upper part of the slope, shrubs and trees in the lowlands. This placement will help to visually align the relief.

  • The entire area of ​​the site must be planted. Between the beds and fruit trees, a lawn or ground cover plants (ivy, barberry, Japanese quince) are planted in empty areas. In addition to the aesthetic component, they will protect the soil from leaching.
  • In hilly terrain, it is impossible to do without paths and stairs. They should be as comfortable as possible, since you will have to move around them more than once during the day. It is recommended to make the width of the paths and the height of the steps of the stairs the same throughout the territory, this approach will help to avoid injuries.
  • Paths are arranged on a conditionally flat surface. To visually smooth out the difference in heights, they are made sinuous.
  • Stairs, steps are necessary on steep slopes. If the slope is very large, then at least one side is equipped with railings. The optimal width of the tread is 25-30 cm, the height of the riser is 15 cm. The slope of the entire structure should not exceed 45 °.
  • If the flight of stairs is large, then rest areas are built, from which you can change the direction of the ascent. The presence of more than 10 steps suggests a concrete base, which will provide stability and prevent the entire staircase from “slipping”.
  • Terracing will help to properly equip a site with slopes. The size and shape of the sites is based on their purpose, for example, one width is needed for a vegetable garden, and another for a gazebo with a barbecue.
  • Zoning of the site is carried out taking into account its location relative to the cardinal points. Shading is also taken into account, shade-loving plants are planted in such places, you can install a bench for reading.
  • When planning, it should be remembered that the more terraces are organized on the territory, the lower the height of the reinforcing walls. Accordingly, their construction is easier. Each deck should ideally have its own drainage system.

Slope strengthening

Prevention of slipping of the loose mass of rocks is carried out by carrying out various fortifications. The method of fixing the soil depends on the steepness of the relief.

  • Natural strengthening. For relatively gentle slopes (up to 30°), creeping plants are used to form a decorative cover. Branched roots will create a natural frame. Willow, lilac, dog rose are planted in the lowlands. Over time, the developing roots of shrubs will also securely hold the soil together.
  • Geomaterial. An excellent solution is geotextile or geogrid. The material is spread on the site and covered with soil. Over time, the soil twitches and turns green. Such a strengthening does not imply a change in the relief. The protective layer covering the material is resistant to adverse weather conditions and chemical influences. The service life of the product is 50 years.

  • mound. Fixing measures can be carried out by means of an embankment. But when implementing them, it should be remembered that the embankment occupies a usable area, so it is rational to use it in spacious areas. Another disadvantage is regular sprinkling, that is, after a certain period of time, the soil is selected at the sole and sprinkled on top of the slope.
  • Retaining walls. Walls made of natural materials (stone, wood) look advantageous and practical. The fortification will protect the slope from destruction and delimit the space due to terracing. They can be installed on hilly terrain with any elevation changes.
  • Low walls (up to 80 cm), which play a more decorative role than a functional one, are equipped on their own. The construction of a massive structure, designed to prevent the landslide of soil masses to a greater extent, should be entrusted to professionals.
  • Gabions. Modular designs are widely used by landscape designers. Gabions are easy to install, they are filled with pebbles, coarse gravel, rubble stone. In the voids between the material, you can lay the ground, and then in the spring, the unaesthetic mesh with cobblestones will hide behind the green growth. Modules are purchased from the manufacturer or made from wire yourself. Stone walls, with penetrating sprouts, give the territory a nobility, a visual aged look.

  • When designing reinforcing structures, the forces acting on overturning and shearing are calculated. The strength and durability of the walls is given by means of a foundation, the thickness and depth of which depends on the height of the supporting wall, its purpose and the type of soil.
  • The supporting part of the wall resists vertical loads. Availability drainage system when building walls is a must. It will prevent the base of the wall from being washed away by rain and melt water.
  • The most commonly used material for building walls is stone. Artificial or natural boulders are laid both on the solution and without it. With the "dry" method of laying, soil is laid in the voids, which is sown with seeds. Unfortunately, the lack of mortar makes the wall not a particularly reliable structure during prolonged rains and during spring floods.

  • Brick is also very popular. Clinker masonry can be discharged or deaf. The material allows you to build walls of any configuration, winding and zigzag shapes.
  • Wooden elements fit harmoniously into the surrounding landscape, but due to their special characteristics, their use as a fortification is not advisable. Of course, treatment with special preparations will extend the life of the wood, but again, this is only a temporary protection. This design requires regular maintenance.
  • If, when erecting walls made of stone and brick, the height of the structure should not exceed 70 cm, then the use of concrete allows a similar figure of 3 m. Here you can use factory-made concrete slabs or pour the concrete mixture into the prepared formwork.

In conclusion, I would like to sum up some results:

  • a land plot with a difficult terrain will cost less, but at the same time, the costs of its arrangement will be noticeably higher than a flat area. Conclusion: no savings;
  • voluminous work on tying a residential building to the terrain, the location of recreation areas and garden beds is fully compensated by the overall original appearance of the site. Conclusion: the difference in heights gives more opportunities for the implementation of non-standard ideas than a flat terrain.

House on a slope or difficult terrain

Choosing a building site country house, we rejoice when we find a perfectly flat area, and we are upset if the location suits us, but the area has a complex terrain. Do not worry about this, because a talented architect can always turn the shortcomings of the site into its undeniable advantages. The only question is: how much will such an exclusive cost?

Features of the architecture on the slope

The future construction costs and the choice of the project of the future house largely depend on the features of the relief. The relief is determined by the slope of the surface, which is calculated as the ratio of the difference in the height of two points of the terrain to the distance between them horizontally, which is the tangent of the angle of inclination of the line to the terrain. The slope is measured in fractions or percentages.. For example, climbing 10 m while moving 100 m diagonally corresponds to a slope of 0.10 or 10%. Depending on the magnitude of the slope, the sections are flat (the slope is not more than 3%), with a small slope - from 3 to 8%, medium - up to 20% and steep - over 20%.

Slope formula: (slope = a/b x 100%) where a is the height difference, b is the distance
between points

Of course, flat areas are optimal from the point of view of construction, but in this article we will not talk about them. On sites with a small slope, construction can be carried out in several ways.:

  • put the house on a level ground, for which soil is poured from the side of the slope. At the same time, you can save on an individual project and build a cottage according to any of the standard ones you like.
  • the lower (ground) floor of the house to cut into the slope. In this case, as in all others (that is, in areas with an average and steep slope), construction is possible only according to an individual project.
  • building a house on a slope involves multi-level house, each level of which is shifted along the slope(terraced and cascade-section houses). The most difficult and costly, at times, option.

Naturally, the question may arise: is it possible to level the slope, ensuring a smooth construction site? As practice shows, changing the natural structure of the relief is extremely rarely advisable, since it is associated with large labor and financial costs, as well as with a violation of the state of the environment (movement of groundwater, soil layer, vegetation, etc.). That's why at construction on difficult terrain it is better to turn to "organic architecture", the main canons of which were developed by the American architect Frank Lloyd Wright. This is architecture “inscribed” in nature — “enveloping” trees, “climbing” the slope, repeating the most remarkable features of the relief, which allows the house to organically dissolve in the surrounding landscape. The formation of a rational slope profile is achieved by giving it an appropriate steepness, terracing and general planning.

The technical side of the issue of building a house on difficult terrain

When searching building sites for houses experts advise choosing the most elevated and dry place on the site. This is due to a number of reasons:

  • First, buildings located below the top of the hill are an obstacle to the movement of cold night air, as a result of which it stagnates and forms a so-called cold pocket. At this point, the temperature can be up to 9 ºС lower than the ambient temperature.
  • Secondly, precipitation can accumulate at the bottom of the slope, the earth becomes swamped there, which creates serious difficulties for the construction of the foundation.
  • Thirdly, construction at the highest point allows you to optimally solve the problem of drainage, which is quite acute for areas with difficult terrain, and organize unhindered natural runoff of surface water. If the soil is sandy, then surface drainage is sufficient, but if the soil is clayey, it is also necessary to arrange. The linear surface drainage of the site helps to divert water from the foundation of the house, cutting off the streams of rain and melt water flowing from the slope to the base of the buildings with a line of channels.

Of great importance for construction on a slope is the composition and features of the occurrence of soils, as well as groundwater. In some cases, in order to eliminate or weaken the softening and destructive effect of groundwater on soils, to reduce and eliminate filtration pressure, it is necessary to make artificial dewatering. According to, to achieve the required lowering of the groundwater level, the following types of dewatering devices are used: trench drainages (open trenches and ditches), closed tubeless drainages, tubular and gallery drainages, reservoir drainages and dewatering wells of various types.

There are many difficulties in designing houses on slopes and their subsequent construction. The task of the architect is to turn them into pluses. Of great importance for the formation of the architectural image of the house is the direction from which the entrance to it is carried out - from the foot of the slope or from its top: when "recognizing" the house, its perception changes. In the first case, as a rule, the building is located so that we see it completely. In the second, only the “top” of the building is visible, that is, those floors (or floor) that are at the top of the slope. We enter the house, and suddenly it turns out that it is much larger, that it has not one or two, but three floors. There is a gradual "disclosure".

If we talk about the technical issues of erecting a building on a difficult terrain, then the main role here is given to the features of the soils occurring on the site. It is one thing - a homogeneous soil or a dense layer that can serve as the basis for the foundation. In this case, you can fill it by designing it so that it can resist the pressure of the slope. And it is a completely different matter if the soil lies in heterogeneous horizontal or, moreover, inclined layers that can slide down the slope. Under these conditions, it will be necessary to build a foundation on piles. The nature and depth of groundwater should also be taken into account.

Terracing of slopes is used to prevent slipping of the soil. Artificial change in the relief of a slope (slope) should be provided to prevent and stabilize the processes of shear, slip, extrusion, scree and soil flow, including landslide flows.

Since the house is partially buried in the slope, increased requirements are placed on the hydro and thermal insulation of the building in order to avoid condensation and leaks on the walls. It should also be necessary to provide for the presence in the house, since part of the premises will remain without the possibility of natural ventilation.

slope exposure

One of the most important characteristics of a site with a difficult terrain, taken into account when designing buildings, is its exposition - a combination of steepness and slope orientation. We already talked about the steepness (slope level) at the beginning of the article, let's consider the concept of orientation. Orientation is expressed in azimuths or bearings. The azimuth geodetic scale of the horizon has 360º, counting clockwise from north. According to the orientation of the slope, the territory is divided into sections corresponding to eight points - north, northeast, east, southeast, south, southwest, west, northwest.

The most favorable slopes for construction are those facing south and southeast.

It turns out that the orientation of the slope, no less than the geological features of the site, affects the decision on the possibility or impossibility of construction. The slopes facing south and southeast are most favorable for this., and those that are oriented to the north or west are unfavorable. And that's why. The slopes facing south and southeast are well insolated (lit by sunlight), the winds from the south side blow weaker, which ultimately partially saves on heating the building. In this case, even the use of alternative sources of heat production - solar installations - can become economically viable.

Experts are unanimous that the northern slopes are completely unsuitable for building a house(with the exception of areas with a hot climate). Insolation here is insufficient, strong cold winds blow. It is very difficult and, most importantly, more expensive to make a home comfortable in such conditions. Building on the western slopes should also be avoided, but for a completely different reason. In the afternoon, they are exposed to the active effects of sunlight, which can lead to overheating of the premises and the discomfort of the people in them.

Based on the analysis of the exposure of the slopes, a decision is made to exclude certain areas of the territory from the main building. They can be used for other functional purposes.

It should be taken into account that building on a slope is not always possible. In particular, if the study of soils showed the likelihood of a landslide. Of course, something can be done in this case, for example, to install foundation piles with a depth of 20 m, if this, of course, is economically justified. The customer must decide for himself whether he is ready to incur large financial expenses. Sometimes the site offers a beautiful view of the sea, mountains or other landscape beauty, which is of decisive importance for future owners of real estate on a slope.

And yet, before building a house on a site with difficult terrain, it is recommended to without fail conduct a thorough soil survey. For example, in the West there is such a practice. Before making a decision to build on any site, its potential owners contact the design bureau. Architects study the features of the relief and give an opinion on how economically justified the construction there is. We practically do not have this stage. Moreover, in practice, there were cases when all the architect's convictions had no effect on the customers, and construction was stopped at the zero cycle stage, as the customer's money ran out. As a result, he was left without money and without a home.

It must be understood that on difficult terrain, economical construction does not work. The costs of the zero cycle (digging a foundation pit, monolithic and drainage works, constructing retaining walls, etc.) can exceed the cost of the house itself. Everything here also depends on the cost of land in a given place, sometimes the cost of a site with a difficult terrain can be an order of magnitude lower than nearby sites with a flat surface, in which case the costs of a zero cycle can be justified.

Climbing the slope, the house completely loses the basement

Choice of house type

Although construction on a slope or on difficult terrain is carried out exclusively according to individual projects, all of them can be divided into two types in one way or another:

  • stepped houses
  • houses of varying heights.

The former have a stepped shape corresponding to the slope of the plot being built up, and are divided into cascade-sectional (consisting of sections of equal height, shifted vertically by half a floor or a floor) and terraced. Terraced houses consist of one-, two- and three-story buildings, running both along and across the slope. At the same time, the roof of the lower part of the building is a terrace-balcony for the higher one. If cascade-sectional houses are designed for construction on slopes with a slope of 7 to 17%, then terraced houses are at least 25-30%.

The second type of buildings - houses of variable number of storeys have a long side across or diagonally to the slope. At the same time, they have a roof at the same level and a different number of floors in different parts of the building, which depends on the difference in relief. The construction of houses of variable number of storeys is possible on slopes with any slope.

An example of a rather unusual implementation of building a house on a slope. In this case, it would be more accurate to say on the cliff. Construction of a building designed by architect Indrek Allmann (Tallinn).

The upper volume of the house hangs like a cantilever over the patio. The support of the house is a welded structure. The base under it was strengthened with the help of 40 piles driven into the rocky ground to a depth of six meters.

Features of the organization of construction on a slope

The organization of a construction site, even on flat terrain, is sometimes associated with some difficulties. On difficult terrain, there are even more difficulties. First, you need to find a place to store building materials. To do this, sometimes you have to remove part of the slope in order to create a flat comfortable platform. At the same time, another problem immediately arises: what to do with the open land? After all, not all of it will be required for backfilling. Well, if the site is large, but if not?

One of the most important tasks is organize driveways so that any complex equipment could get to the construction site. The choice of types of earth-moving machines and cranes is determined by the characteristics of the site. Before proceeding with construction, it is necessary to protect the site from the slope runoff of storm water. First of all, this applies to open pits and trenches. And one more task, the solution of which is most often necessary before the start of the main work, is the construction of supporting structures to stabilize landslide processes. Such structures are of three types: retaining walls (on a natural or pile foundation); pile structures and pillars that serve to fix unstable sections of the slope and prevent displacement of soil masses along weakened surfaces; anchor fastenings - as an independent holding structure (with base plates, beams, etc.) and in combination with retaining walls, piles, pillars.

Having finished with the theoretical part of the topic, let's move on to the consideration concrete examples construction country cottages in areas with difficult terrain.

Implemented projects for the construction of houses on a slope or difficult terrain

Spa complex on the territory of a private estate

In Tolkien's novel The Lord of the Rings, hobbits built houses in spacious and cozy burrows on the hillsides. It seems that the author of this project, architect Vladimir Shkurinsky, followed their example, inscribing one of the buildings of the vast estate - the building of the spa complex - into a high green hill. This is a vivid example of how a complex and seemingly inconvenient difference in relief can not only be beaten, but also turned into an undoubted advantage, giving the structure a unique originality.

Spa complex on the territory of a private estate in the vicinity of St. Petersburg

Fitting the house into the landscape was one of the most difficult technical challenges. An excavator cut off part of the slope in order to deepen the future structure into it. Most of the soil (about 1,600 m²) was removed, the rest of the soil was used for backfilling, leveling terrain differences and raising the soil level between the building and the lake. The slope was reinforced with a special rubber mesh () and a retaining wall made of stones.

When designing the complex, the features of the relief were taken into account, in particular, the slope pressure and possible soil movements under the influence of groundwater. Therefore, the foundation was made as rigid as possible - tape-slab, the walls of the building - monolithic. The walls have been treated pasting waterproofing, and then mounted in two layers (5 cm each) Penoplex heat-insulating boards (extruded polystyrene foam). A reinforcing plaster mesh was attached to the walls, along which a layer of plaster was applied. Then they were faced with porcelain tiles. In places where the building crashes into the slope, due to the nature of the underlying soils, no additional measures were required to protect the walls from the damaging effects of the soil tightly adjacent to them, since the selected finishing material is characterized by increased performance.

Precast concrete villa

The future owners of this house wanted to have a comfortable home with a wide range of diverse rooms. But it was impossible to expand the building area, and it was not necessary to increase the height of the house, so as not to introduce dissonance into the surrounding landscape. The decision was partly prompted by a three-meter difference in relief on the site in the form of a rather steep slope.

Villa made of monolithic reinforced concrete in Vilnius with an area of ​​422.7 m². Architect Alvydas Seibokas.

The building, consisting of three rectangular volumes, was erected at its foot. The lower volume, partially cut into the slope, serves as a pedestal for the main one, raising it to the top of the hill. The third, the smallest, was placed on the roof of the second. As a result, from the side of the main façade, the building is perceived as a two-storey building, revealing its three-level structure only on the façade facing the river valley. The height of the house was visually reduced, slightly drowning each subsequent volume into the previous one. And by moving them relative to each other, they made room for terraces, equipped on flat roofs. The structure was supported by concrete piles lowered to a depth of 6 to 13 m.

The project of the house was developed by Konstantin Ermakov, director of the Atrium Plus company (St. Petersburg). The cottage is built on a plot with a relief difference of 7 m. The entrance to the house is organized from the upper level. The basement floor is designed on two levels: the lower one has a garage for two cars, the upper one has a billiard room, a sauna, a rest room, technical rooms.

Cottage on a plot with a relief difference of 7 m

A large difference in relief required planning with the help of retaining walls. Part of the slope was cut away so that the first floor windows facing the area formed by the retaining wall could be made to a standard size.

Villa Eclipse

Sixty acres is a plus, but a large difference in relief and a ravine bed of a stream that limits the territory on both sides is a clear minus. True, the authors of this project, architects Vladimir Sinitsyn and Artem Chernikov, did not agree with this and proposed a bright and original solution based on geoplastics. Geoplastics is the creation of an artificial relief, or rather, the vertical planning of a territory for the purpose of its architectural and artistic transformation. Thanks to these transformations, it was possible to organize a private space completely closed from prying eyes in front of the house and organically fit the building into the landscape. The plan of the building is L-shaped and has five levels (technical floor, basement, first and second floors, an office on the roof).

The site has undergone significant changes, because a large amount of excavation was required: a third of it was reduced by cutting the soil to a depth of 4 m. Thus, the territory was divided into two zones of different levels. It took 1,200 m³ of concrete to build a retaining wall in this area. In front of the house, there was an exit from the basement floor to the lower private courtyard (mark - 4 m). Behind the house - exit to courtyard at the level of the first floor (zero mark).

House on the slope of the coast of the Sevastopol Bay

The building is made of monolithic reinforced concrete with an area of ​​369 m². Architect Igor Shipovich. The house has an elongated shape along the coast. residential part its facing the sea. The architecture of the building is completely subordinated to the terrain. It was the curved lines of the coast that made it possible not only to divide the house into two floors, but to make it multi-level: on the same floor, separate rooms are at different heights and are connected by small passageways.

There are six levels in total: three on the ground floor and three on the residential floor. The game of relief complicated and diversified the appearance of terraces and various places for outdoor recreation.

Glulam cottage

Cottage made of foundation blocks and glued beams near Novosibirsk with an area of ​​420 m². Architect Alexander Buzytsky. This cottage is located at the very descent to the bay. Its basement, built from foundation blocks, gradually grows from zero to a full-fledged floor. One of the end facades, on which the main entrance to the house is located, faces the street, the other faces the bay.

The walls of the two main levels of the house are crowned with a radial combined roof. The building adjoins a garage-canopy for storage of snowmobiles and other small equipment. Its green roof raises the lawn to the very windows of the house. Huge display windows overlooking the pine forest open the space of the fireplace room for communication with the natural environment.

Glued beam house

Residential building made of glued laminated timber in the Ivanovo region. Design and construction - "Volkovskiye tekhnologii" company. The slope was partially cut to get a flat area and pour a monolithic slab under the foundation. In the future, part of the slope was again filled up, creating, in the opinion of the author of the project, a relief more interesting than it was originally. In a monolithic plinth cut into the slope, there is a garage for two cars, motorcycles and Utility room.

The entrance to the house is possible from two sides. The relief was strengthened with natural stone, which required 600 tons of it. Rain and melt water passes through a system of channels and enters a pond located quite far from the house. When building on difficult terrain, it is important to properly strengthen the slope.

Brick house

Brick house with an area of ​​500 m² in Samara. Architect Dmitry Karpov. The site on which this house was erected was a steep slope, in fact, a ravine, so the future building had to fit into a rather complex landscape. In addition, the geological examination of the soil revealed the presence of karst cavities. They were formed as a result of leaching of limestone rock by groundwater close to the surface.

Given the peculiarities of the soil and landscape, the only right decision in these circumstances was the construction of a pile foundation. The piles were driven into the bulk soil, and a monolithic reinforced concrete slab was laid on their heads. With heavy load-bearing walls of the cottage, this foundation design is one of the most reliable. AT architectural plan the building forms a composition of squares combined in pairs with each other, united by a central part. The difference in relief made it possible to get out of the pool arranged in the basement to the ground level. And the garage and the gym located above it are vertically shifted by half a floor - they are accessed from the intermediate platforms of the stairs.

Without a doubt, ideal condition for the construction of a country house is a flat area, but this is not always the case - quite often suburban areas are located on the slope of a ravine or on the edge of a river slope. In such situations, building a house is somewhat complicated, and there are many reasons for this, among which landslides and soil movements occupy a special place. In general, building a house on a slope is a little more difficult, and if you are faced with such a task, then you need to start solving it by studying the basic information.

House on a slope: advantages and disadvantages

Not everything is as scary as it might seem at first glance - at one point, building a house on a slope creates some difficulties, and at another, as they say, it makes it easier to solve some problems. It is for this reason that the first thing you need to start studying the issue of erecting such buildings is to familiarize yourself with their advantages and disadvantages. Let's start with the shortcomings - they include the following points.


And, of course, design complexity - a house on a hillside does not have standard projects. It should be understood that if you are faced with the decision to build a house on a slope, you will have to turn to builders who will develop a project for quite a lot of money, where they will take into account everything necessary to ensure that your house is warm, comfortable and durable. Now, as for the merits of the house on steep slope. They are also not few.


Even irrigating land with a house on a slope is an advantage - proper terracing of the slope will retain the right amount of water for vegetation to grow. In general, complete harmony - in the sense that the disadvantages of building a country house on a slope are almost completely offset by the advantages.

How to build a house on a slope: the foundation is everything

The foundation of the house is a responsible structure that fully ensures the reliability and durability of the building - in the case of a house on a slope, this moment is very relevant, and this stage of construction should be taken responsibly. Let's face it - not every type of foundation is suitable for such buildings. Of all the existing diversity, only three varieties are used.

In general, making a foundation for a house on a slope is a rather complicated matter, and it does not depend on the type of foundation chosen. Not only does it need to be correctly calculated taking into account local factors, it also needs to be erected correctly - in general, this is a matter exclusively for professionals.

We build a house on a slope: features of the arrangement of the slope

A properly designed slope is another guarantee that the building will stand for a long time and nothing will happen to it. Just do not think that the terraces will help you cope with the arrangement of the hill one hundred percent - yes, they play an important role, and flat areas greatly reduce soil movement. But besides this step, you need to think about other possibilities, which, together with the terraces, will serve to reliably strengthen the slope.


In general, it will be necessary to carry out a full-fledged set of measures aimed at solving such issues as strengthening the slope, preventing landslides and soil erosion.
And in conclusion of the topic on how to build a house on a slope, a few words about the signs that indicate that building a house on your site will require a lot of money to strengthen the slope. These are natural phenomena - ravines, lopsided trees, poles and other similar things - they speak of a rather large moving layer of soil, which can reach up to 3m. By the way, the moving layer of soil, or rather its thickness, is a direct indication of the depth of the foundation and the depth of the base of the retaining walls, through which the site is terracing on the slope.
