Before starting construction with your own hands, each future owner must calculate approximate cost the buildings frame house. The calculation is necessary so that you can accurately determine whether your finances are sufficient to complete the construction. If the resulting amount is slightly more than you can afford, the house design can be slightly adjusted - reduce the size of the house, replace materials with cheaper analogues, etc. Each calculation when building a frame house with your own hands is approximate, and the total amount spent on construction is usually more than the original planned percentage by 5.
How much does it cost to build a foundation?
The most popular type of foundation that is poured for an inexpensive frame house is a strip foundation. It is a cement mixture poured into a mold. The construction of such a foundation can be done independently, thereby saving up to 50% of the cost of the foundation.
Foundation construction work is divided into 2 categories:
- preparatory work
- pouring the foundation
The first category includes soil research, calculations of the future frame weight of the house, marking, excavation, construction sand cushion, installation of a reinforcement frame or a mesh frame, all work on the installation of formwork, etc. You can also add here the purchase of all the necessary materials, the quantity of which must be calculated in advance. If you decide to carry out this work yourself, then you will only have to pay for sand or ASG for the pillow and its delivery. You can buy ready-made formwork, or put it together yourself from boards and film (they also need to be purchased). The calculation is made using data on the perimeter of the foundation, its depth and height above the ground. In matters of foundation depth, proceed from the weight of the frame structure.
The second category includes pouring the foundation cement mixture. Here you will have to pay the cost of concrete, its delivery by a mixer and, most likely, the work of several workers. Concrete hardens very quickly, so you will need help leveling it in the formwork.
On average, the cost of a DIY foundation will be from $2,000.
If you order a foundation from a turnkey company, the price will increase several times.
Construction of walls and partitions
So, if your foundation is already ready, you can start building the wall frame. To do this you will need:
- technical drying timber (price per m3 is 135-140 dollars, depending on the type of wood and % humidity)
- insulation (Basalt, stone wool, mineral wool. Basalt fiber mats on a metal mesh). The price will be 20-30 dollars per roll (min. wool).
- waterproofing (45-50 euros per roll) and vapor barrier (47-55 euros per roll)
- OSB boards (OSB-3 board 9x1250x2500 mm (Format-Europe) – 550 rubles per sheet
In addition, you may need universal galvanized screws, universal galvanized screws, a hacksaw, self-tapping screws, a wood drill, and nails.
All work can be carried out independently, which will also save at least a third of the amount requested by turnkey companies.
If you decide to build a house from SIP panels, their cost will be:
1500х1250х174 – 100 dollars
2500x1250x224 – $117
2800х1250х174 – 120 dollars
2800x1250x224 – $127
Price may vary depending on region, order size and delivery.
How much does it cost to build frame house from the developer - we read.
Roofing: materials and prices
Roof - essential element at home, so it’s not worth saving on the roof. First, it requires deciding which roof will be erected. It can be single-pitch, double-pitch or more complex. The cost of the roof is also affected by how the attic space will be used. Residential attic needs high-quality insulation.
A house with a pitched roof will cost you less.
In addition, the final cost of the roof will depend on the price of the roofing material. Slate is one of the cheapest materials, but it does not have such characteristics as modern materials– for example, a soft roof. Soft roof It costs more, but it is much easier to install. In addition, it does not produce noise during operation of the house.
Don't forget about treating wood with fire protection. You can order the treatment of the frame base from fire organizations or carry it out yourself. Calculation of the amount of impregnation for self-processing depends on the number of layers.
Materials you will need to build a roof
The purchase of material constitutes the main cost column for roof construction. What materials will you need to install a frame roof?
- To build a rafter system, you will need a beam with a cross-section of 15x5 centimeters.
- The Mauerlat will also be made from timber - only the cross-section should be 10x10 centimeters.
- The board or timber for the sheathing is selected based on the parameters of the future roof. The beam is calculated based on the dimensions of the perimeter of the house and the pitch between the rafters.
- Consumables - screws, nails and others - will be required for fastening rafter system and other parts of the roof.
These materials will be required to construct the roof frame. However, the roof needs to be insulated and insulated, and for this you will also need:
- Insulation (mineral wool and polystyrene foam).
- Waterproofing.
- Vapor barrier.
- Foam for processing joints.
- Glue.
Today, frame construction is more popular than ever before. The fact is that calculating the cost of constructing the same panel house shows: the cost of such a structure will be at least 30% less than the cost of a similar house made of any other material. Calculating the consumption of lumber and the cost of cladding for a frame house is not so difficult. This will be discussed in the article.
Selection of materials and their influence on the calculation
It goes without saying that ready materials frame construction will occupy the largest share in the total estimate. Their expenditure will constitute a significant part of the budget allocated for construction.
First of all, attention should be paid to the consumption of lumber. In particular, the following materials will be needed for a panel house:
- Beam of various sections;
- Edged board with a cross-section of at least 5 centimeters;
- Edged board with a cross section of 2 centimeters;
- Tongue and groove boards with a section of 2.5 centimeters.
An example of calculating the amount of timber for a frame house in the design documentation
Calculating the cost of cross and rack beams is not so simple: here it is necessary to take into account the size of the future structure (its area), as well as the thermal insulation material that will be used during construction.
Calculation of the roof structure of a panel house and the choice of roofing material will also affect the final cost of construction. However, calculating the amount of roofing material is not so difficult.
In addition to wood processing industry products, it is necessary to calculate the consumption of materials for the following:
When calculating the cost of post and cross beams, you need to take into account the size of the future house, as well as the type of insulation used.
By the way, calculations of materials for the structures described above should be performed only after the owner of the house has decided on the material of the house frames and roof. They make everything else “dance” too.
Of course, if a person is ready to spend money to create a safety margin at home, then the calculations need not be made so scrupulously, but frame houses are also built, most often, precisely because they are cheap.
Wall insulation scheme for a frame house Ambient temperature and its influence on the calculation
The warmth in the house will depend on the climatic features of the area where the house is being built. This is a well-known fact. The only time when the climate can be ignored is if it is being built country house, in which exclusively summer accommodation is planned.
Here, in order to calculate the quantity, you will definitely need a table indicating the thermal resistance coefficients various materials, and all the indicators must be calculated separately both for the walls of the building and for the roofing pie, otherwise all the heat will simply escape through the attic floors and there will be no use.
Based on such calculations, you can get the final required thickness walls and roofing pie, which will be sufficient to retain heat in the house (according to the thermal resistance coefficient, again).
Layout of racks in a frame wall Also, it is much easier to make calculations if you know in advance all the parameters of the materials (for example, the weight of all structures) that the manufacturer has installed.
Usually, frame houses are supplied as house kits, so it will not be difficult to find out all these values (usually all this is indicated in the documents that necessarily come with the house kit itself).
It is interesting that if a house is built using Canadian technology, from sandwich panels, then a minimum of materials for its finishing will be needed. The fact is that insulation is already installed in such panels in advance, that is, they have a heat-insulating layer.
Device ventilation gap will require additional costs Most often, manufacturers as thermal insulation material sandwich panels are used specifically mineral wool. It turns out that the outside of the house will not need to be insulated at all (which means that the cost item for external insulation and leave only the internal calculations).
Calculation of thermal resistance indicators must be carried out separately for both the walls of the building and the roof.
Calculation of individual building structures
It is clear that before you build a frame house with your own hands, you first need to include in the estimate the cost of material for building the roof and foundation.
Wiring diagram frame house Insulation of a frame house, both internal and external, is also an extremely important event, except in cases where houses are built using Canadian technology, using pre-insulated sandwich panels.
The cost of insulating a frame house will be approximately up to 20% of the total estimate, provided that factory insulation was not used in the house kit, and up to 10% if it was used.
If you build a frame house with your own hands, then great importance there will also be a consumption of lumber, and not even so much for the walls, but specifically for the roof. The same attic beams the cost can be almost half of the price of the entire panel house box.
We have already discussed the calculation of lumber for the walls of a panel house, so attention should be paid to the roof. Of course, if you buy ready-made house kits, then there will be no difficulty: the manufacturer has calculated everything in advance.
But how much lumber is needed for a panel house and its cladding, provided that you are building a frame house with your own hands - this is much more difficult. The insulation of a frame house has already been discussed above.
Roof
When designing the roof of a house, it is necessary to take into account not only total weight and the load of attic floors and beams, but also the weight and characteristics of the roofing material itself.
An example of a cost estimate for the construction of a frame house Special attention You should also pay attention to the roof structure, during the construction of which it is necessary to take into account the wind rose in a certain area (that is, from which side the wind will blow more often - on that side there will be a greater load). Materials for construction are also selected taking into account these criteria.
In fact, it's quite important criteria for selecting materials and calculating their costs. If you do not take into account the same wind rose, then the roof on one side may leak, become leaky, roofing material without proper reinforcement and fastening, it can simply be blown away by strong winds, not to mention hurricanes and other natural troubles.
Nuances that must be taken into account before starting the construction of the roof of a frame house:
- It is not recommended to install a high and sharp-angled roof on a house in an area where extremely strong winds prevail (otherwise, you will have to calculate the roof with a fairly large margin of safety, which will inevitably lead to a significant increase in the entire construction estimate);
- roof sheathing should be installed at more frequent intervals to increase the safety factor;
- for the rafter system it is necessary to choose a stronger beam (than roofing beam the thicker it is, the stronger it is, everything is extremely simple here);
- better to choose something tougher roof covering, since it will be stronger (slate instead of metal tiles or corrugated sheets, for example).
If there is frequent wind in the area strong winds, it is better to buy a more rigid roofing material such as slate.
Foundation
For frame panel buildings, lightweight types of foundations such as shallow strip (most often monolithic), pile or even columnar foundations are usually used. True, we must take into account the fact that columnar foundations are suitable only for small frame houses, for a summer residence, for example.
General scheme frame house devices As for piles, the simplest option is screw foundations. To calculate the number of piles, it will be necessary to take into account the entire mass of the house and the load on one square meter area from a solid foundation.
It will be necessary to take into account the condition of the soil in the area that was allocated for the construction of the building. It is also necessary to take into account the heaving of the soil and the depth of groundwater.
For example, if the foundation piles are not buried deep enough, then during cold weather the foundation will simply lift the house, which will immediately lead to the appearance of cracks of various sizes and partial destruction of the frame structure.
After all, what mistake do people often make when building houses on their own? They calculate the foundation only by the weight of the house - that’s all. But this cannot be done, because it is necessary to take into account many other criteria that were outlined above. But it’s better to have specialized specialists do this - it will definitely be more reliable.

You can watch a video about how materials for building a frame house are calculated.
Many people dream of owning a nice home. The best option such a structure is a frame house, the construction of which does not require significant Money and allows you to independently perform all the calculations necessary for construction.
Features of using a frame house
Such a structure has its own operating rules, which are determined by the technologies used in its construction.
Fire protection.
This real threat, which must be taken into account when building a frame house. All wooden structures needs to be soaked by special means, which will make the tree more resistant to fire. Wherever possible, it is advisable to use material for a frame house, which is much less susceptible to fire than wood. It can be cement bonded particle boards and plasterboard slabs. For insulation, mineral wool should be used, which is a non-flammable item.
To eliminate the possibility of fire, install chimneys and heating systems in strict accordance with the rules. Particular attention should be paid to the installation of electrical networks and installation of electrical appliances.
Ecological condition and protection of the material for the frame house from rodents.
Wood is environmentally friendly pure material. Some doubts may be raised by laminated timber and OSB boards, which in Russia are made mainly from aspen. However, their environmental safety is ensured by the use of harmless resins and other adhesive materials in the manufacturing process. It is also advisable to use environmentally friendly mineral wool for insulation instead of polystyrene.
The material on a frame house made of wood makes it comfortable to live in, since wood “breathes” much better than any other building material.
Prevention of rodent control for a frame house is no different from rodent control in other types of buildings. Can be made reinforced concrete monolithic foundation, install in underground vents and other places where rodents may enter metal mesh. Good protection against rodents is used as a material for a frame house. OSB boards. This is facilitated by the internal structure of the slabs, which is a physical obstacle for rodents and the adhesive compositions used in the process of their manufacture, which are lethal to them.

Service life of a frame house
Based on data from specialized literature, the structure will last for at least 30-50 years. However, practice shows that frame houses, which were built more than a century ago, have survived to this day. And this despite the fact that such means for protecting the material on a frame house, which are currently available, simply did not exist before. Therefore, it can be assumed that such structures are preserved for a long time because people constantly lived in them and monitored their condition.
The duration of operation of a frame house will depend on the quality of the material, wood, its reliable treatment with antiseptics and substances that prevent its fire (fire retardants), correct installation all systems in the building and its insulation.
The maintainability of such a structure is much higher than that of any structure built from a material different from the material for a frame house.
Mistakenly, many believe that buildings built using frame technology are only suitable for summer cottages. Many people assume that frame houses are akin to the well-known “Finnish” houses, which in fact cannot be lived in at any other time of the year, except in the summer at the dacha. In fact, residents of countries with harsh climates such as Canada, Sweden, Norway, and Finland feel very good in modern frame houses.
Such structures are not only convenient for living, but they have good properties thermal energy saving. To do this, it is necessary to select the appropriate properties and calculate the material for the frame house. In this way, an insulated building cools down much longer than an ordinary brick house.

Frame house foundation
Shallow option available strip foundation for a building measuring 6x10 m (see Image 1) with the calculated amount of material needed to make the foundation. The data is summarized in table 1.
Table 1
Note. All suitable formwork boards must then be used for the frame posts
Shallow foundations are currently widely used, since they are practically not pushed out of the ground during the freezing process of the soil. winter time. In addition, this type retains heat in the room better than a column or stilt foundation. The depth is 40 cm, the elevation above the surface is 50 cm.
A separate type of such structures is a frame-panel house. It is a structure based on a durable frame covered with panels. The thickness of the walls is usually at least 30 cm. Wind loads, the weight of the building and everything in it, and the weight of snow in winter are taken by wooden supports from timber or boards fastened together, which create the necessary strength and rigidity for the frame. The panel-wall of such a structure also creates stability for it, since the wall, like a monolith in the form of a multilayer sandwich, also resists deformation.
When the problem arises of how to calculate a frame house, this is usually understood not as a force calculation, but as a calculation of the amount of material for a frame house. For this, there are standard calculation methods, knowledge of which will help you correctly navigate your financial capabilities.

Tired of the city bustle and noise? A house outside the city will solve this problem. But such a purchase may be too expensive. In this case, all that remains is to build own house, and technology will help you save frame construction. This article will discuss the stages of building a frame house and necessary materials for this.
The foundation of a frame house is the basis
Any structure begins with a foundation. It takes on the entire load of the house, and the stronger the foundation, the longer the house will last. Thus, a poorly made foundation can lead to distortion of the veranda, windows, and doors, which is why they will no longer close tightly over time. It is likely that this will cause cracks to appear in the walls of the structure.
To correct foundation defects, you will have to additionally spend up to fifty percent of the total construction cost. For a responsible, correct and thoughtful choice of the foundation of a frame house, it is necessary to take into account some points.
The calculation of the foundation must be carried out taking into account the above factors. The purpose of the calculation is to determine the load on the foundation and soil, to provide possible problems. In order to calculate the total load for the foundation, it is necessary to take into account the weight of the house, the furniture inside it and the people arriving there. Most often, for frame buildings They use pile and columnar foundations, since the weight of the buildings is small. Which does not at all prohibit the use of slab or ribbon types foundations.
Features of a columnar foundation of a frame house
This type of foundation consists of pillars buried in the ground. They can be round, rectangular, square. The cross section for such pillars can be either variable (the lower part of the pillar is expanded) or constant (in the form of a parallelepiped or cylinder). Due to the expanded lower part (base) of the pillar, the bearing capacity of such a foundation increases. This will contribute to a more even distribution of the weight of the house, and when the soil heaves, it will serve as a barrier to pushing the pillars upward.
The columnar base can be made of monolithic concrete, brick and even wood. Wooden poles are not very durable, no matter how hard you try to protect them, sooner or later they will begin to rot, which is why their load-bearing capacity is also lost. This basis is only relevant for the construction of temporary structures.
Using bricks to build a columnar foundation is not very convenient and requires a lot of labor. It is quite problematic to stack a column of such material inside a well. However, this material for poles has high strength, which is important. Alternatively, you can stack the bricks into a pillar shape and lower finished design into the well. Of course, you need to let the mortar between the bricks dry.
The most common and the best material for a columnar foundation is monolithic reinforced concrete. A foundation with a variable or constant cross-section of a pillar can be laid by first digging a rectangular or square hole. It is better to make the width of such a hole forty to fifty centimeters larger than what is needed for the pillar itself. This is necessary in order to place the formwork there, which will give the pillar its future shape. A frame made of reinforcement is placed inside the formwork, and then concrete is poured. After drying concrete mixture the formwork is dismantled and the pillar is covered with earth.
Wells for a columnar foundation can also be made using hand drill. The depth of the wells is determined by the level of freezing and also depends on the density of the soil. The drilling diameter varies from one hundred fifty to four hundred millimeters. The drill is very convenient and practical TISE-F. With its help, you can drill a well with a diameter of up to 20 cm. Due to the plow available with the drill, soil can be cut off from the walls of the bottom of the well. Thus, the lower part of the well has an expansion in the form of a hemisphere.
For a frame made of reinforcement, as a rule, two to four thick rods (ten to fifteen millimeters in diameter) are used, which are tied together with mounting thin reinforcement. The required volume of cement is calculated taking into account the diameter and depth of the well. The pillars are placed under the future load-bearing walls and at their intersections. The heads of the pillars should be fifty centimeters above the ground. This will provide a gap, thanks to which you can avoid rotting from dampness of the lower part of the structure of a wooden frame house.
At weak ground (marshy area, peat soil) it is recommended to use a screw-pile foundation. Such piles are steel pipes, in the lower part of which there are blades. Due to them, screw piles are screwed into the ground. The blades also serve as a barrier to squeezing it out of the ground. One such pile can withstand a load of four to six tons. Its length can be up to twelve meters. When screwing screw piles It is imperative to ensure its vertical position. The main advantage of this type of foundation is the absence earthworks, which affects finances. There is no need to use reinforcement and concrete.
Strip foundation - reliable, but expensive
The tape base is a closed tape of unbroken rigid concrete structure. It is laid under all load-bearing walls of the frame house. Compared to columnar foundation, tape requires large labor costs during construction in terms of land work and volume concrete material and therefore more reinforcement.
As a rule, during construction this type of foundation is used when it is necessary to build a basement or ground floor. In such cases, it is necessary to take into account the freezing of the foundation, which acts as a basement or plinth wall, and the depth groundwater. Such a structure on the ground side will need to be treated with waterproofing materials, and preferably. To do this, you will need materials made of foam glass or expanded polystyrene. The width of the tape is made ten to twenty centimeters greater than the thickness of the wall.
To avoid transverse deformation of the foundation, its height must be made twice as large as the width of the tape itself.
Monolithic reinforced concrete slab as a foundation - this is the most reliable option. This base has the largest supporting area when compared to other types. Main feature such a foundation is that it can and should be used on soils, calculation bearing capacity which does not allow the use of other types of foundations - the forces of soil heaving can least of all affect it. The thickness of the slab can be ten or more centimeters.
At the very beginning for construction monolithic slab it is necessary to level the surface, make sand and gravel cushion and compact it. Stacked on top waterproofing material, insulation, which is covered with film. After this procedure, it is formed reinforcement cage(use ribbed rods with a diameter of twelve to sixteen millimeters). On average, about fourteen meters of reinforcement are required per square meter of foundation. When the frame is ready, the whole thing is poured with concrete.
Construction of a house frame - purchasing materials
The frame in this type of construction can be used either wooden or metal. The calculation of the material for an ordinary frame house has already been done many times by builders - we will provide ready-made figures, traditional for houses from 60 square meters. m. up to 80 sq. m. You can purchase all building materials for a frame house project at any construction market.
Yes, when using wooden frame its construction will require seven to nine cubic meters timber. It is advisable to use a section of one hundred by one hundred and fifty millimeters. The following materials can be used for cladding the frame:
- moisture-resistant premium glass-magnesite sheet (can later be plastered or painted);
- particle board or oriented strand board;
- moisture resistant plywood.
For example, for a house 10 by 6 meters, wall cladding can take up to six oriented strand boards measuring 125 by 250 centimeters.
