Building materials calculator for home construction. Calculation of materials for building a house from foam blocks

To correctly use the calculator and calculate the cost of building a house with maximum accuracy, you must carefully read on the site about the technologies of building houses that are used in our construction company. You can start with the most common - how to build a house of gas silicate blocks, or to build houses of brick.

Calculating the cost of a house on our calculator is not a difficult task at all, but nevertheless, it requires a careful approach. In order to correctly calculate the cost of building a house and analyze the calculation results, we ask you to familiarize yourself with this hint:

  • the algorithm includes a model of a square building, without verandas and balconies;
  • the height of the ceilings adopted in the model is 2.75 meters;
  • the house construction calculator takes into account the total area of ​​all rooms in the house, including the boiler room, sanitary facilities, stairs, and not just the living space;
  • correctly specify the distance from the object to the Moscow Ring Road;
  • construction cost calculation is performed by a calculator in current prices for building materials;
  • the final result is affected by many factors, so you should consider that the result will be indicative; for accurate estimates contact the company's specialists.

You can print the calculation results or send them to your email.

If the cost of the house obtained on the calculator suits you, then you need to come to our office and discuss in detail all the details of the construction with our designer. After that we will be able to accurately calculate the cost of construction of the cottage and provide you with an estimate.

The price of building a turnkey house

Today, to build your own country house is no longer an unattainable dream. The latest technology allows in the shortest possible time to build the house itself and to finish, minimizing costs. At the appeal stage, a qualified specialist company makes a detailed estimate. This takes into account all the project documents provided, and the personal requirements of the customer. Focusing on the ready estimate, the client can assess the potential costs and adjust them if necessary.

The main process is preceded by the so-called zero stage, at which the selection of a building plot takes place and a project is drawn up. Upon its completion, the cost of building a cottage is already clear. Then construction begins directly, in which the following steps are distinguished:

  • Production of the base and monolithic slab. The stage includes not only the construction itself, but also the delivery of materials to the construction site. Approximately the cost of the foundation is 8% of the total value of the house.
  • The construction of the house itself - walls, interior partitions, roofs. The main percentage of the total price of the construction of the cottage falls just here. This is 20-25% of the cost.
  • Warming and facing of a facade. The price in this case depends on the high cost of the finishing material, as well as the total area of ​​the cottage, and is 10-15%.
  • Interior decoration. This stage begins with engineering communications, followed by a complete repair. The cost of building a turnkey house includes not just a rough finish, but also the installation and debugging of equipment, the performance of all work that makes the building fully habitable. This is the most expensive stage, which, moreover, largely depends on the cost of finishing materials. And their price may vary at times. Roundly, we can assume that this stage is 40-50% of the total value of the house.
  • Registration of the territory. Stage may include the installation of gates or decorative structures, landscaping and so on.

Of course, this list can be adjusted depending on the specifics of a particular object and the wishes of the customer. The final price for building a turnkey house is made up of many factors: the total area and number of rooms, the high cost of materials, the initial complexity of the work, the specifics of the relief, etc. The complexity of the architectural form is also important: the presence of shaped elements, irregular layout, etc. Sometimes in the process of implementing individual tasks, the use of specialized equipment is required, which also affects the final price of the construction of cottages.

Building a house with our calculator is easy and simple. Good luck!

Despite the fact that foam concrete was invented in the early twentieth century by the Swedish architect A. Erikson, who tried to create an artificial stone with the properties of wood, in our country it was started to be used in the 1930s, but it became widespread only in the years of perestroika.

The use of foam blocks in the construction will save cement mortar and speed up the construction process.

The advantage of foam concrete is its frost resistance, durability, airtightness, environmental friendliness, fire resistance, as well as the ability to pass steam, resistance to microorganisms, simplicity and low cost of manufacture and laying of blocks.


The scheme of the bath of foam concrete.

Due to the above properties, foam concrete and blocks of it, unlike aerated concrete, can be used in construction for the following purposes:

  • construction of load-bearing walls in low-rise construction;
  • the construction of partitions, including in high-rise buildings;
  • the use of foam blocks as a heat-insulating material;
  • pouring foam concrete monolithic frame or permanent formwork.


Foam blocks production scheme.

And these are just a few examples of the use of lightweight concrete and products from them.

For performance of various tasks foam concrete of various density is required. For example, a material with a density of D600-650 and higher is needed to create the bearing walls of the building, and for a simple filling of the monolithic frame of the house, the density of D400 is sufficient.

For the construction of foam concrete blocks, it is necessary to take into account some features of this building material.

Material transport


The chain ligation system when laying the wall: a is a thickness of one and a half bricks, b is a thickness of two bricks, c is a thickness of two and a half bricks.

When transporting, it is desirable to use manipulators, and foam blocks, protected by packing tape, should be placed on pallets, in order to avoid chipping of corners. Failure to follow the seemingly simple rules may affect the appreciation of the construction of the object.

The most modern and convenient way of laying is made on a special glue, which is applied to the surface of the foam block with a thin layer.

However, this is applicable only when building a house of blocks that have exact geometric shapes and sizes, in other cases it is advisable to use a cement-sand mortar.


Perform masonry wall with a recess in multi-ligation system.

In any case, the construction technology requires the reinforcement of the masonry, and then the creation of the armored belt at the top of the erected wall of the house.

As a rule, after construction work, such walls are faced with brick, siding, trimmed with various plaster mixtures and many other modern finishing materials. The interior of the house can also be plastered on the grid or finished with plasterboard - according to the taste of the owner.

Counting the number of foam blocks


Laying in a tight way: a - spoon row; b - tychkovy number: 1–4 –sequence of actions.

The calculation of the required number of foam concrete blocks for construction is quite easy to do if you are friends with geometry. It is required to know for sure:

  • wall thickness;
  • partition thickness;
  • the perimeter of the house or structure;
  • masonry height;
  • sizes of windows and doors and their quantity.

For the calculation, you should select walls with different thickness and divided into groups. For example, in the first group include outer walls, in the second - internal partition walls.

Then, the total length of the walls in a separate group is measured and the total area of ​​the doors and windows is calculated, also in accordance with the group. Further, it is necessary to calculate the masonry volumes in each group, for which the length, height and thickness of the walls are multiplied together, and the window and door volume calculated earlier is subtracted from the results obtained.

The division into groups is due to the fact that, as a rule, foam blocks of various sizes and, accordingly, volumes are used in construction.

An example of calculation for the house 7x10 m

The sequence of laying foam blocks: a - single-ligation system; b - multi-ligation system; c, d - multi-ligation system mixed way (numbers mean the sequence of masonry).

At the first stage the dimensions of the building are determined. The house is 7x10 with a total length of partitions of 13 meters, a height of 3 meters, with a thickness of external walls of 0.4 meters and partitions of 0.1 meters. Windows - 5 pieces, 1.8x1.2 meters in size, interior doors - 3 pieces, 2x0.9 meters in size, entrance door - 1 piece, size - 1.8x1.2 meters.

At the second stage, the size of foam blocks is selected. In this case, the following dimensions will be used, in mm: for external walls - 200x400x600, for partitions - 100x300x600.

The third stage is the calculation of the number of blocks required for the construction of load-bearing walls. The perimeter of the box will be (7 + 10) x2 = 34 m. The total area of ​​the walls of the box without openings is calculated as follows: 34x3 = 102 square meters, where the number 3 is the height of the masonry. In the same way, the area of ​​technological apertures is calculated, which in this case after calculation will be 12.6 square meters. After the deduction (102-12.6), the net area of ​​the external walls without windows and doors is 89.4 square meters.

The next point is the calculation of the volume at a wall thickness of 0.4 meters. For a simpler solution of this problem, it is necessary to calculate the area of ​​one block 200x400x600, while multiplying its length by the height in meters, (0, 6x0.2 = 0.12 sq. M). Then the wall area of ​​the box is divided by the area of ​​one block and the number of foam blocks for external walls is determined (89.4: 0.12 = 745 pcs.).

Thus, the construction of the box at home requires 745 foam blocks, which will be 35.82 cubes.

At the fourth stage, the calculation of blocks for partitions is carried out, for which the length of the partitions is multiplied by the height (13x3 = 39), in meters, and the area of ​​the interior doors is subtracted (39-4.8 = 34.2), and the result is divided by the area of ​​the partitioning block equal to 0.18 m. Thus, the number of blocks for partitions is calculated (34.2: 0.18 = 190 pcs.), which amounts to 3.42 cubes.

Total, for the construction of the house will require 745 foam blocks of 200x400x600 mm and 190 pieces of 100x300x600 mm. The total volume will be 39.24 cubic meters. In addition, you need to remember to purchase 2-3% of the total volume of foam blocks for an emergency. From the calculation it is clear that this construction is available to the general population.

If you decide to build your own house, the first thing you need to find out is the amount of materials you need to build it.

The process of counting all the necessary things is quite capacious and time-consuming with respect to time, but it is extremely necessary for the stable and successful construction of your home. However, for all other parameters, this procedure will not cause you many problems.

Order of action

1. Determine the size of the house. Find out the exact footage available to you for housing, distribute all rooms and rooms in this area and select their placement.

2. Use a professional forum or perhaps a specialized site, which provides statistical data on how much each type of building material is needed for a certain size. If you could not find the necessary information online, go to the store and consult with the seller. Ask him what material is best for you, which materials have the highest quality indicators, and how much of a particular product you need to fill in the entire footage.

3. Think about the material itself. Perhaps you originally planned a wooden house made of felled wood or specially prepared slabs. However, such construction will spend not only a lot of your money, but also time. Modern technologies allow to obtain material with higher rates of "vitality", and at the same time at a reasonable price. The assembly process will be much simpler, and the end result will look cleaner and cleaner.

4. View your notes again. Make an adjustment, if it is necessary after going to the store, calculate the quantity and price of all products and do not forget to take all with a five percent surplus for unforeseen situations. Pick the most optimal supplier and place your order. From this point on, construction can officially begin!

Step by step calculation of materials for the construction of a small house

Calculate the amount of materials for the foundation

The basis of the basics foundationtherefore, we first calculate the need for sand, cement and crushed stone for a strip base of a house, measuring 4 by 6 m, as it is the most difficult to calculate, but first digression into terminology. For most calculations, you need to know exactly and distinguish only two concepts - area and volume. When two quantities are multiplied, the length and width is the area denoted in square meters (m²). If height is added, then this volume is the product of three quantities, it is denoted by cubic meters, cubic meters (m³). Science is not complicated, you can not even use a calculator.

For example, we define the volume of the basement with a width of 0.5 m, a length of 4 m, a depth of 1.2 m. Multiplying all we get a volume = 2.4 m³. Then we multiply the readings by 2, we have 2 sides of 4 m each, getting a value of 4.8 m³. We do the same calculations for the side with a length of 6m, i.e. 0.5 * 6 * 1.2 = 3.6, then * 2 = 7.2 m³. Now we simply add up our volumes and get the total value of 4.8 + 7.2 = 12 m³. We call to the nearest concrete unit, find out the price with the delivery of two six vat "mixers" and get not just the volume of the foundation, but the required amount of concrete and its cost.

For example, if you equip the base of the foundation blocks of the five, FBS 5, then we calculate the volume of one block, it has a width of 0.5 and a height of 0.6 m, suits us, and they are 2.4 m, 1.2 and 0.9 in length. Multiply 0.5 * 2.4 * 0.6 = 0.72 m³, and divide our volume by the volume of 1 block, obtaining the required number of pieces (12: 0.72 = 16.5). It is possible to buy 17 blocks, or operating with their length, to pick up the exact quantity, but the main thing is that it is cheaper to compare, not forgetting the crane and mounting from the wheels.

If we prepare concrete ourselves, then we take the proportion of concrete, for example, 1: 4: 6, respectively, cement, sand, crushed stone, and proportionally divide our volume. The sum of all components 1 + 4 + 6 = 11, so we divide 12 m³ by 11, getting the volume of one share, part = 1.1 m³. Now we multiply it by the share of sand = 4.4 m³, crushed stone = 6.6, and cement can also be in mind = 1.1 m³. The density of cement, somewhere 1.2 and above, so 1.5 tons of cement is enough. The sand is also multiplied by 1.5, since it is read that in 1 cube of sand 1.2-1.7 tons, getting 1.5 * 4.4 = 6.6 m³. Crushed stone is sold in cubes, there is no need to recount. The only thing that needs to be remembered is that the wind can inflate some sand, and rubble “drown” in wet soil, and they are not sold in “grams”, therefore it is necessary to round up theoretical norms and sometimes some material remains. better than not enough, a bucket of gravel only buy from a neighbor.

Calculating bricks

Multiplying the width and length of the house by its future height, we obtain the draft volume of the building, from which it is necessary to subtract the volume of windows and doors. To calculate, it is customary to take 400 ordinary single bricks per cubic meter of masonry, 300 one-and-a-half bricks, and 200 doubles. We divide our net volume, minus openings, by “standard”, and we get the required value, and multiplying it by the price and form of delivery, we usually sell them in packs, pallets, we find out the amount needed for the purchase.

Calculation of materials on the roof

The calculation of the roof is somewhat different, it is already square. The length of the slope, for two sloping roofs, we take 3 m, multiply by the length of the building, round it to 7, because of the gables, and multiply the result by 2 slopes (3 * 7 = 21 * 2 = 42 m²). It will be necessary to cover this area, and dividing it into the area of ​​the roofing material, for example, in a 10 m² roofing sheet, we get rolls, sheets, and the modern service cuts long materials along the required length. To convert an area into cubes to determine the need for wood is also not difficult, sometimes it is enough to say the size of the roof in a store, and they immediately say volume. Do you want yourself? We take the length of the board and multiply by the width, this is the area of ​​one. Dividing the entire area, we obtain the total number of boards, now multiply by its thickness and obtain the required volume. Calculate the proportionality of concrete, piece materials easier to count. But what about the pediment, it is triangular?

We divide it in half from the ridge to the base, getting instead of an isosceles one, two right triangles. If one is turned over by 180 ° and applied to the second, then we obtain a rectangle with a height equal to the height of our gable and a width equal to its half. In other words, we simplify the triangular area to a rectangular area, the calculation of which is familiar to us. Trapezoidal roof can also be decomposed into a rectangle and 2 triangles, combining which, we obtain the sum of rectangular areas.

We are not going to determine the number of nails or cleats in one evening, but if you are so meticulous, then this is not a problem in our age. There are a large number of Internet sites and just programs that not only define cubes and tons for us, but can also help with design.
