How high is one floor? Norms for multi-apartment and individual houses. Floor height in a multi-storey building How many meters is a 4-storey building

Apartment house differs from the individual one in that it has several separate exits to the land or apartment plot. Also, houses are recognized as multi-apartment houses, the height of which exceeds 3 floors, including underground, basement, attic, etc.

Classification of the number of storeys of buildings

Allocate the following classification residential buildings, which differ in the number of floors:

  • Low-rise (1 - 3). Most often, they include individual residential buildings. The height of the building, as a rule, does not exceed 12 meters;
  • Mid-rise (3-5). The floor height of 15 meters is a standard five-story building;
  • Elevated number of storeys (6-10). The building is 30 meters high;
  • Multi-storey (10 - 25):
  • High-rise. From (25 - 30).

The number of storeys of a building is considered solely by the number of floors above ground. When calculating the number of storeys, not only the value from floor to ceiling is taken into account, but also the value of inter-storey ceilings.

Apartment buildings. Number of floors and height of buildings

AT modern projects The "golden mean" is the height of one floor of 2.8-3.3 m.

Only highly qualified specialists are engaged in the construction of multi-storey buildings, since this business requires not only high costs, but also has many nuances.

There are the following types of multi-storey buildings:

  • Panel. Belongs to a series of budget. It has a high construction speed, but poor heat and sound insulation. The maximum number of storeys is about 25, depending on the design. In a residential area, the height from floor to ceiling is 2.5 - 2.8 m, depending on the size of the panels.
  • Brick. The construction speed is quite low, because the construction is costly. Thermal and sound insulation indicators are much higher than panel ones. The optimal possible number of floors is 10. The average height of each is 2.8 - 3 m.
  • Monolithic. These buildings are quite diverse, because everything rests on the bearing capacity of concrete. They have high seismic resistance. To improve heat and sound insulation during construction, brickwork can be used. Allows you to build about 160 floors. Height from floor to ceiling 3 - 3.3 m.

How to get a permit for an IHS? What does a builder need to know?

Permitting authorities follow the order of development and agree on documents for individual housing construction according to RSN 70-88. Thanks to them, not only the accuracy of building up the site is determined, but also the layout of the dwelling and auxiliary buildings. This project needs to be well thought out, because what is not displayed in the plan will be recognized unauthorized structure and is subject to demolition or re-approval.

Without permission, that is, before the approval of the plan and receipt of documents, work should not begin, otherwise serious problems may arise. In order to find out exactly what documents will be required to start building, you should read the "Code of rules for the design and construction of SP 11-III-99".

In 2010, SNiPs were recognized as binding rules. They regulate activities in the field of urban planning, as well as engineering work, design and construction.

In order to obtain permission, you need to contact the BTI or the architectural department of the city to provide:

  • application for a building permit;
  • documents establishing the right to use the site;
  • certificate of field determination of boundaries, placement of buildings, etc.;
  • cadastral plan of the site;
  • House project.

Once issued, the permit is valid for 10 years.

Individual housing construction

The number of storeys of an individual residential building is calculated based on the number of residents and personal preferences. The minimum height of a room according to SNiP is 2.5 m. If the height does not meet these parameters and turns out to be lower, then this room will be considered unsuitable for habitation.

How many floors can be built on the site? On an individual plot it is permissible to build three storey building about 9 meters high. In this case, both underground and above-ground premises are taken into account.

What can be erected in the garden?

Many are interested in the question of what can be erected and how many floors can be built independently on a garden plot? In addition to outbuildings, on a garden plot, you can build a dwelling that is not suitable for registration. When erecting buildings on a garden plot, SNiP should be followed.

The height of a 5-storey building is a variable parameter that depends on many factors. Usually, it is customary to answer such a question in a standard way - 15 m, and in the average value, this is approximately how it turns out. In fact, when calculating the height of a five-story building in meters, you need to know exactly what kind of building we are talking about, because experts know that the height of five floors can be 14 meters and more than 20. Until relatively recently, this was the most common type of houses, gained popularity because of the ability to save on elevators and fire fighting devices.

The height of any house is an important design indicator.

How to determine the approximate height of a building

The history of the construction of five-story houses goes back more than one decade, for example, in the Soviet Union it began with the construction of experimental buildings as part of a frame-building project. panel houses in 1948.

It cannot be said that before that there were no five-story buildings in the country, but this was the first attempt to build from standard parts according to a certain principle.

The mark of different types of buildings may vary

The development was carried out by Gosstroyproekt, Mosgorproekt and the Academy of Architecture of the USSR. Iron consumption for the frame, even after the introduction of a more economical principle, turned out to be large, so two years later Moscow, Leningrad, Magnitogorsk and other cities began building panel houses without a frame.

Khrushchev - the most common type of housing construction in 4 and 5 floors. It was the result of the need to provide housing a large number people, due to their movement to large construction sites or the urgent need to resettle in big cities communal apartments, which were the result of rapidly passing industrialization.

Construction type "Khrushchev"

The need to restore the destroyed National economy, capital investments for the modernization of industry and the simultaneous construction at public expense have led to the fact that brick houses no amenities, single or coupled one-story houses and multi-apartment buildings, known as "Stalinka", were practically replaced by construction from standard reinforced concrete panels.

The beginning of the era of five-story buildings

The 5-storey format replaced the 4-storey ones due to the possibility of building more apartments without the need to build an elevator, which was also being saved at that time. The height of the "Stalinist house" exceeded the standard Khrushchevs due to the height of the ceiling, which was at least 3 meters, as can be seen in the photo.

Stalinist type of buildings

The construction of houses of this period is also characterized by the construction of a higher ground floor, designed to accommodate shops, ateliers, post offices and other socially significant facilities. Even workhouses of this type were designed for 125 years of operation, and holding overhaul further extended their service life.

Multi-pitched roof, also with long term operation, further increased the height of the building. According to the standard standards of this period, it turned out that the height of a 5-storey building, based on ceilings of 3 meters and a multi-pitched roof, can be considered starting from 20 m, even if the building did not have a special floor for shops, which was built above the rest.

Buildings of the Brezhnev type

Model building

The style of construction of five-story panel houses is not accidentally called functionalism. From standard project all individual features in the form of pediments, stucco moldings and other architectural elements have been removed. Nevertheless, calling such a construction faceless, it is very problematic to unambiguously calculate the height of a five-story building from panels.

Mass transient construction did not provide for the placement of additional decor on buildings

The height of the ceiling in different projects reached from 2.48 m, sometimes - 2.6 or 2.64 m, at a later time they began to build a height of 2.7 m.

In terms of 5 floors, 20 cm difference is already a meter of additional height.

At the initial stage, the roofs were tiled or slate, in the era of the struggle against architectural excesses they began to be made flat, because they were cheaper. The bituminous roofs had a lower attic space, the height of the first floor, the depth of the basements, and so on, were different.

Flat-roofed houses are hot in summer and cold in winter

Definition of vertical dimension

In determining the height of the panel typical house what matters is the project, its number, the parameters provided by the developers, and much more, an example in the photo.

For a more accurate definition of design parameters, refer to the building plan.

The following can be cited as classical calculations:

  1. The foundation and the roof are 1.5 + 5 = 6.5 m in total and 15 m, if we consider the height of three meters, and it is approximately the same, because in addition to the vertical size of the rooms, it is necessary to take into account the ceilings - all together it turns out 21.5 meters .
  2. If we assume that the house is without a basement, and the vertical from the ground is 1.5 m, then you can easily find out what is the height of a 5-story building in meters. If the size of each floor, together with the ceiling, is from 3 to 3.3 m, and even a roof of 5 m is added (according to the standardized parameter), then this is a total of at least 22 m.
  3. To determine the vertical size, you need to know the standard vertical size of the floor, but it did not exist as such, because different types of projects were developed. Some were with a basement and a pitched roof. There were options with a basement and an attic. Houses were built with a basement or a high ground floor. Do not forget the developments in which there was a basement of 2.5 m, but the roof was flat.
  4. The vertical size of the most standard project without a plinth, with a flat roof and a semi-attic is really about 15 m. But it is about, because you need to know the distance to the ceilings and the width (thickness) of the ceiling.
  5. The very first buildings, still built of brick, could be up to 14 meters in vertical size. This depended on the then absolutely small height assumed in the building for a standard apartment and amounting to 2.48 m. The layout of the Khrushchev houses was not interested in such trifles in the early stages.
  6. Modern construction practically does not use such projects with their small dimensions and economy mode. To date, it is simply impossible to determine how far from the ground an apartment located on the fifth floor is, if you do not know what project the townhouse was built on. A five-story building, taking into account the roof, can be from 22 to 28 meters vertically, and such figures are quite likely, given that today GOST standards are practically not observed.

Modern 3D house plan models

As for typical parts, some of them have not been used for a long time, some are not produced, and new developments have appeared that allow modeling the desired height without resorting to building blocks developed specifically for standard projects in production.

How to deal with projects

In Soviet times, due to the harsh conditions of war and post-war times, the country was forced to save money, so the neoclassical era, in which beautiful buildings of the Stalin era were built, was replaced by strict functionalism, depleted typical buildings that formed entire arrays.

Outwardly, Stalinka is distinguished by various decorative elements.

Only by the state of some deterioration outwardly can one distinguish representatives of entire periods of Soviet architecture. But at that time, people were happy when they got new apartments and moved out of communal apartments. Below is the classification of houses:

  • big, beautiful houses with Soviet paraphernalia, elements of the classical style (plinths, columns, stucco moldings), usually built of brick and finished with plaster and natural stone - these are "stalinkas". They have a good view, a high ground floor, the size to the ceiling is at least 3 meters. Hence the approximate calculation - about 20 (and sometimes more) meters;
  • Khrushchev - low and unpresentable in appearance, was not designed for long-term operation, which is why it is being demolished in large cities. The advantage of these buildings was the possibility of an accelerated elimination of the shortage of housing. It was built from standard parts and very quickly, but there were quite a few minuses. For example, the ceiling was only 2.48 m from the floor, and only later this figure increased to 2.60 or 2.64 m;
  • Brezhnevka - houses that began to be built under Brezhnev, differed not only in ceiling height - from 2.7 m, but also in much more spacious stairs, platforms, construction using the Unified Construction Parts Catalog. Projects were taken into account with higher ceilings, which means that the height of these then new buildings exceeded the obsolete buildings familiar to the eye with a height of 14–15 meters. If the Khrushchevs seemed to be weak-sighted and cringed against their background, then this was only due to more advanced projects that took into account not only the fact of obtaining housing, but also the convenience of living in it.

Basic moments

The housing renovation program adopted in Moscow has led to the massive demolition of these panel or brick structures, but in other cities they are not yet being demolished so massively. There is no talk of demolition of Brezhnevkas yet. All these nuances are taken into account when buying a secondary home.

Demolition of a Khrushchev-type building

For the first floor has importance the presence of a basement or basement, the height of the windows, the presence of a store or a socially significant institution in the house. To determine the height of a 5-storey building, it is not always necessary to take measurements.

The process of building an apartment building must meet certain requirements. They apply to both high-rise buildings and buildings with a small number of floors.

All standards for residential buildings are prescribed in SNiP 31-01-2003. But this document is quite voluminous and written in a complex language using professional and semi-professional terms, so we will try to explain the material related to determining the number of storeys of buildings in simple words.

Classification of houses by the number of levels

To begin with, consider what houses in height exist:

  • low-rise - buildings whose height does not exceed 12 meters, or 3 floors;
  • mid-rise - the distance from the floor of the first floor to the roof reaches 15 meters, or 5 tiers;
  • high - up to 10 floors and a height of up to 30 meters;
  • multi-storey - up to 100 meters high (up to 25 levels). This category is divided into a number of subcategories I (up to 15 floors), II (up to 20), and III (up to 25) types.
  • high-rise - the minimum number of storeys is from 25 and the height is from 100 meters.

The choice of materials for the "high-rise building" also depends on how many floors it is planned to build.

Floor dimensions in a multi-storey residential building

Depending on the materials used in the construction of the building, the following types can be distinguished:

  • panel;
  • brick;
  • monolithic.

Real estate in panel houses is the cheapest, as buildings do not retain heat well and have very low sound insulation. The tallest of them are 25-storey buildings, and the height of each floor ranges from 2.5 to 2.8 meters.

The second type - brick - is quite laborious, respectively, and is built much more slowly. Thermal conductivity and sound insulation are much higher. The height of such buildings is not more than 30 meters (10 floors). A separate tier does not exceed 300 cm in height.


If you plan to build a building up to 160 floors high, then choose a monolithic type. Monolithic buildings are the most labor-intensive, have the highest heat and sound insulation (to further enhance the performance, the walls are additionally lined with bricks), and are the least susceptible to destruction during natural disasters. In this case, the distance from the floor of the first level to the roof of the floor reaches 3.3 meters.

Normalization of the lift dimension

During the construction of houses, if the building exceeds a height of 5 floors, an elevator must be installed. Depending on the number of tiers of the building, from 1 to 4 elevators can be installed in the house.

The minimum width for an elevator structure is 2.1 meters and a depth of 1 m (to accommodate medics with stretchers). The size of the hall in front of the elevator depends on the size of the elevator itself, but the width should not be less than 1.5 meters. A wheelchair must fit in the door (smaller doorways are only allowed if there is another one).

It's important to know! The number of elevators in the building also depends on the number of apartments and, accordingly, the number of people living on the site.

Fire safety standards for residential apartment buildings

Construction work on the creation of each individual building, and even more so a residential building, must comply with safety requirements. The rigidity of control of these rules is determined by the number of storeys of the house. The most "soft" they are in residential buildings up to 18 meters high (up to 9 levels), since such a number of storeys corresponds to the length of a mechanical staircase installed on fire service vehicles.


The design of the building must provide for an emergency exit. If the number of floors is less than 9 floors, only 1 exit is allowed, if the building has from 9 to 18 tiers, there must be at least two exits. If the house belongs to high-rise or type III multi-storey buildings, an emergency exit must be on each floor.

Another important requirement for buildings with a height of 10 levels or more is the presence of a smoke-free staircase. Such platforms are very convenient for evacuation, but during operation in everyday life they cause discomfort. Therefore, the most commonly used practice in the construction of multi-storey buildings has become the design of a conventional staircase hall plus several external stairs.

Fire safety conditions are also applied to the corridors. If the length of the room is not more than 40 meters, its width should be 1.4 m, if the length exceeds the specified distance - the width is 1.6 m. In such long corridors of multi-storey buildings, it is recommended to install fireproof doors every 30 meters.

Important! It is also allowed to install doors with reinforced glass on staircases and elevator platforms.

The entire supporting structure of the building, walls, partitions located in the house, as well as landings, must be made of materials that are the least susceptible to combustion. The same rule applies to floors between basement levels.

The dimensions of the vestibule in a residential building

A vestibule in a residential building is the space between the entrance door to the apartment and the door to enter the house / entrance (for the 1st floor) and the area between the apartment door and the stairs (for the remaining tiers of a multi-storey building).


In accordance with SNiP 31-01-2003, a distance of 1.5 m is allowed as the minimum depth for a vestibule. If the building is located in areas with a low average temperature, it is allowed to build a double vestibule.

Additional requirements

In addition to the elevators high-rise buildings there must be stairs. Sites at each level are designed depending on the number of storeys of the house and the number of apartments on the floor. The minimum width is set to 1.25m.

In residential buildings there are also basement tiers. Their height is usually 1.8 m. But depending on what equipment is planned to be installed, the height can reach 2.3 m. According to safety standards, this area must have two exits.

It is important to note! Dimensions ground floor also depend on the height of the building. The height of the basement in multi-storey buildings is 2.1 m, and the distance from the ground surface should not be more than two meters.

An attic is always built above the last floor of the building. Most often, its height is 1.6-1.8 m.

All information in this article is taken from official sources. Therefore, it will not be difficult for any citizen who wants to purchase real estate in a residential "high-rise building" to independently check for compliance with legal requirements.

The project for the construction of residential buildings, popularly referred to as Khrushchev, was launched in 1957. The construction was aimed at providing housing for every family and reducing mass living in communal apartments.

Khrushchev's vision of the housing issue: a person should live, albeit in a small, but his own dwelling. Based on this, living space reduced to 6-9 m2 for the bedroom and 6 m2 for the kitchen. The height of the ceilings was no more than 2.5 m. At the same time, the height in meters is approximately 15 meters.

What were the first apartments like?

At first, the houses were built of brick, and the height of a five-story building in meters was approximately 14 m. A few years after the start of construction, the architects switched to panel construction of five-story buildings, which significantly saved time and labor costs. Not without innovations in the layout of apartments - in the sockets, the bathroom was shared.

Construction features and nuances

The features of panel Khrushchev include:

  • the height of a five-story building in meters depends on the design series;
  • lack of an attic, a garbage chute, an elevator;
  • load-bearing structures in such a house are external.

Building a house from panels is more like playing with a constructor: large panels and blocks are stacked on top of each other and mounted. This construction method maximizes productivity on the construction site. Consequently, a site for organizing construction is required less, and long and labor-intensive processes are completely excluded. These are the main advantages of panel construction.

And only decades later, people came to the realization that Khrushchev is far from ideal housing: an ill-conceived thermal insulation system, low level noise reduction, little usable space.

Serial construction of panels

Since the beginning of the 60s, they began to build in series, forming entire residential areas with their own internal infrastructure. In total, the construction of the project included about 23 series of brick and different layouts. At the same time, the height of the five-story building in meters was different. It depended on the features of the building.

Basement level with an approximate height of half a meter to ground level, 5 to 2.55 meters plus half a meter to the attic, the total height of a five-story Khrushchev house was approximately 14 meters, if we are talking about panel house, and 15 meters for a house with a full roof and an attic.

An apartment building differs from an individual one in that it has several separate exits to a land or apartment plot. Also, houses are recognized as multi-apartment houses, the height of which exceeds 3 floors, including underground, basement, attic, etc.

There is the following classification of residential buildings, which differ in the number of floors:

  • Low-rise (1 - 3). Most often, they include individual residential buildings. The height of the building, as a rule, does not exceed 12 meters;
  • Mid-rise (3-5). The floor height of 15 meters is a standard five-story building;
  • Elevated number of storeys (6-10). The building is 30 meters high;
  • Multi-storey (10 - 25):

The number of storeys of a building is considered solely by the number of floors above ground. When calculating the number of storeys, not only the value from floor to ceiling is taken into account, but also the value of inter-storey ceilings.

Apartment buildings. Number of floors and height of buildings

In modern projects, the "golden mean" is the height of one floor of 2.8-3.3 m.

There are the following types of multi-storey buildings:

  • Panel. Belongs to a series of budget. It has a high construction speed, but poor heat and sound insulation. The maximum number of storeys is about 25, depending on the design. In a residential area, the height from floor to ceiling is 2.5 - 2.8 m, depending on the size of the panels.
  • Brick. The construction speed is quite low, because the construction is costly. Thermal and sound insulation indicators are much higher than panel ones. The optimal possible number of floors is 10. The average height of each is 2.8 - 3 m.
  • Monolithic. These buildings are quite diverse, because everything rests on the bearing capacity of concrete. They have high seismic resistance. To improve heat and sound insulation during construction, brickwork can be used. Allows you to build about 160 floors. Height from floor to ceiling 3 - 3.3 m.

How to get a permit for an IHS? What does a builder need to know?

Permitting authorities follow the order of development and agree on documents for individual housing construction according to RSN 70-88. Thanks to them, not only the accuracy of building up the site is determined, but also the layout of the dwelling and auxiliary buildings. This project needs to be well thought out.

to. what is not displayed in the plan will be recognized as an unauthorized structure and must be demolished or re-approved.

Without permission, that is, before the approval of the plan and receipt of documents, work should not begin, otherwise serious problems may arise. In order to find out exactly what documents will be required to start building, you should read the "Code of rules for the design and construction of SP 11-III-99".

In order to obtain permission, you need to contact the BTI or the architectural department of the city to provide:

  • application for a building permit;
  • documents establishing the right to use the site;
  • certificate of field determination of boundaries, placement of buildings, etc.;
  • cadastral plan of the site;
  • House project.

Once issued, the permit is valid for 10 years.

Individual housing construction

The number of storeys of an individual residential building is calculated based on the number of residents and personal preferences. The minimum height of a room according to SNiP is 2.5 m. If the height does not meet these parameters and turns out to be lower, then this room will be considered unsuitable for habitation.

How many floors can be built on the site? On an individual plot, it is permissible to build a three-story house with a height of about 9 meters. In this case, both underground and above-ground premises are taken into account.

What can be erected in the garden?

Many are interested in the question of what can be erected and how many floors can be built independently on a garden plot? In addition to outbuildings, on a garden plot, you can build a dwelling that is not suitable for registration. When erecting buildings on a garden plot, SNiP should be followed.

It is permissible to build two above-ground floors. The height of the house in meters depends on the size of the floor, so the minimum allowable height of one span is 2.2 m.

Is it possible to build a house in a leap year?

In our country leap year considered very unfortunate for the construction of residential buildings, but in some countries, on the contrary, very successful. Is it possible to build a homestead? Of course, in modern realities it is difficult to follow all the signs. First of all, it depends on the owner, because not everyone wanted to build a house in 2016, and many put off this business. But to freeze the project apartment building for a year is beyond the power of even companies.

This will interest you:

Only highly qualified specialists are engaged in the construction of multi-storey buildings, since this business requires not only high costs, but also has many nuances.

In 2010, SNiPs were recognized as binding rules. They regulate activities in the field of urban planning, as well as engineering, design and construction.

Approximately 30 m.
What a source! Logics. Fold each floor by 2.5 m (this is an approximate standard) and + floors between floors and a roof.

Well, the basement usually sticks out by 1-15, the ceiling is a maximum of 30 cm, the ceiling height is 2.5, the attics are different from two to three meters. Well, count 2.5x16 + 0.3x19 (the overlap of the attic and roof can also be calculated) + 1.5 + 2 ...

What is the height of the 9 storey building?

In short, about 50 meters.

don’t worry, everything will be fine .. My cat was gone for 2 weeks, we were all worried, but he crawls on 2 legs, the other 2 were broken. , jumping..

Considering that the 1st floor is about 3 meters, then the entire building is about 45 meters

Have you already climbed higher, where the beast of the cat family will not reach you? You can get off!
African leopards and cougars can make the highest jump. They are able to jump onto a tree branch (or rock ledge) at a height 5.5 meters.In general, cats jump up to five times their height.

Is your cat a cougar by any chance?

Although, my cat jumped from the floor to a tall cabinet, flew two meters, but so that 5 meters))
Yes, it urgently needs to be in the book of records!

nope 🙂 not sick

I bought a decent one for 5 lats.

go to the doctor 🙂 a friend crushed his heels like that

If there are no cracks or fractures, then fastum will most likely help. Well, or my favorite troxevasin: also good for bruises.
But just in case, control the bruised place: if soft tissues are crushed there, there may be complications. You will understand this if, in addition to pain, signs of inflammation appear: redness, swelling.
Then skip to the doctor!

Height - Floor

Page 2

The floor height in multi-storey buildings is taken as a multiple of 600 mm.

The height of the floors and the grid of the frame columns are assigned in accordance with the requirements for the typification of structural elements and the unification of overall parameters. Such limited mesh sizes are due to large temporary loads on floors, which can reach 15 kN / m2, and in some cases 25 kN / m2 or more.

The length of 1 floor can be expressed as ...

The floor height is the distance from the floor of the floor to the floor of the floor above. The height of the upper floor is taken equal to the distance from the floor level of the penultimate floor to the floor level of the attic; at the same time, the height of the attic floor is taken conditionally equal to the height of the interfloor floor.

The floor height is the vertical distance from the floor level of the floor below to the floor level of the floor above, and in the upper floors and one-story buildings- to the top of the attic ceiling.

When the height of the floors is different, the length of the staircase is determined by the length of the largest of the flights of stairs, which should not go beyond the cage, otherwise it will cross the rigal connecting its racks into a spatial frame.

Combinations of floor heights may sometimes not meet the technological requirements of the located production facilities. In this case, during the feasibility study, it is allowed to take the necessary combinations of floor heights while maintaining the absolute values ​​provided for by GOST.

Increasing the height of the first floor by more than 5 m does not have a noticeable effect on the excess temperatures of the working area and hi 4 m can be considered close to optimal for the conditions under consideration.

We assume the height of the floor of the building is 25 m clean, the average water consumption in the riser is 250 kg / h, the diameter of the pipes Dy is 20 mm.

With a floor height of 3 5 - 4 5 m, the warehouse area can be taken approximately at a rate of up to 3 - 4 m2 per 1 L 3 of wood processed by the model shop per year.

With a floor height of 3600 mm or more, additional holes should be provided for the bars of the washing flooring, positioning them so that the distance between the holes in height does not exceed 1800 mm. On the upper floor, additional embedded parts for fastening the guides should be located at a distance of 500 mm from the bottom of the ceiling above the shaft.

It seems to me like the 5th house is equal to 15 meters

If the roof is 18 meters. From the window of the 5th floor, 17 meters from childhood, my brother told ...

15 m in a 5-storey building

Floor ~ 3 meters. 3*5=15 meters

I think it depends on the building itself.
