Frame houses are the most economical in modern low-rise construction. That's why they are very popular lately. Calculating the cost of a frame house allows you to draw up a preliminary estimate. This is not difficult to do, especially since you can use a special frame house calculator online, which will quickly make all the calculations. However, you first need to determine what exactly needs to be included in the calculations.

Frame and frame-panel house
The bulk of the cost of building a frame house will fall on the purchase of lumber. First of all, it is necessary to decide whether the house will be built using frame or frame-panel technology. In the first option, it will be built from a frame, insulation, sheathing, etc. directly on the construction site. In the second case, the building is assembled from a house kit, which is prepared in production conditions.
It is easier to calculate the cost of a house kit, since you just need to add the cost of the foundation to the established price. But panel houses are built strictly according to standard designs and do not provide the opportunity to apply their own architectural solutions. In addition, they are not intended for year-round use. Therefore, private developers usually prefer classic frame (Canadian) houses, which today are built using improved methods.

Requirements for lumber
To assemble a bathhouse or house, you should buy only high-quality timber, then the construction will be smooth and will last for many years. Before calculating the amount of materials for the walls and rafter system, you should assess its condition and only then begin calculations. If the beam is reliable, you can choose blanks by thickness and size, and decide on their quantity. You can do it simpler and ask the manager one question, receiving detailed advice.
If you independently assess the quality of the material, pay attention to the timber - the workpieces must be smooth, straight and free of any defects. Cracks and delamination of wood are unacceptable. It will be good if the timber has already been treated with impregnation against rotting and insects. This assessment can be carried out when purchasing timber and filling out an application in the store. If you contact a developer, he is obliged to check the quality of the lumber. We harvest the wood ourselves, which guarantees the high quality and reliability of our timber.
Materials
To build a frame house, the following materials are required:
- beam;
- OSB panels;
- board;
- plywood;
- foundation materials;
- roofing;
- insulation;
- hardware.
Only after the final decision has been made on the choice of all the main materials can the calculation of the frame house be made; the online calculator will help you deal with this quickly, but will show an approximate value. The foundation is calculated last.
Materials for the frame of the house, its foundation and roof are selected based on the selected architectural solutions, which are determined taking into account a number of factors. For example, the set of materials for the roof depends on what kind of roof structure will be used. In turn, the roofing structure is developed taking into account the climatic characteristics of the region in which the house will be built. Mainly taken into account is the pressure of air masses and the prevailing wind rose.

General information
All the material was ordered in parts - there were 10 deliveries in total, and it turned out that the transportation of the material alone cost 5,000 rubles.
- For the bottom trim, 35 boards with a size of 5*15*0.5 cm were required. One board of this size cost 565 rubles, a total of 19,775 rubles.
- Boards measuring 5*10*0.6 were used for all walls, rafters and top trim, and 98 pieces were required for a 6*8 meter frame. One board in this size cost 380 rubles, and a total of 36,480 rubles were spent.
- The boards, whose size is 2.5 * 10 * 0.6 meters, were used to create jibs, roofing sheathing, subfloor and ceiling. 200 pieces were used, and if you convert the quantity into cubes, then 3 cubic meters. One board cost 195 rubles, and in total they cost 39,000 rubles.
If you add up all the expenses, it turns out that almost 7.5 cubic meters of boards were spent on the house, and money - 100,255 rubles. Compared to other Russian regions, timber in Crimea is the most expensive. But similar material on the mainland will cost you much less. In general, this is a house that you can build all with your own hands. Almost the entire board was used here, and a little later we covered the rough ceiling and floor from this number of boards.
Online calculator
A calculator will help you calculate the materials for a frame house, but only the construction company that will build the cottage can calculate the exact lists of materials, their quantity, and the price of the entire construction. However, many private developers prefer to make preliminary calculations first. This allows you to understand how expensive the house will be. To make a preliminary calculation of the material for a frame house, a calculator is simply necessary.
As a result of calculations using a calculator, it may turn out that the house that you decide to build will be too expensive. In this case, you can postpone construction for a while or try to change the requirements for the planned building. For example, a future homeowner may first build an inexpensive one-story cottage, the design of which includes the opportunity to eventually build an attic and thus expand the area of the home.

Material counting programs are intended for professional use by builders. They are needed for budgeting. However, there are calculator options that anyone can use, regardless of construction skills. A good frame house calculator takes into account all the main and auxiliary materials. Therefore, the data obtained with its help is much more accurate than independent calculations.
It is important to understand that the online construction calculator for a frame house helps determine the amount of materials, but does not take into account the wages of builders. To understand how much the house will cost, including the delivery of materials, workers’ services, the preparatory process, rental of construction equipment and other nuances, you should multiply the amount calculated in the online calculator by 2.
Beam dimensions
When deciding on them, you need to proceed from economic feasibility. We are talking mostly about the thickness of the walls and the thermal conductivity characteristics of the material. Let's consider this in two variations: a summer (country) house and a building for permanent residence.
Thickness and width
The width of the timber should concern the developer only if permanent residence is planned, and even then not always - after all, any wooden wall can be insulated with effective thermal insulation, thereby avoiding losses for “street heating”. For a summer house, it is quite possible to use a section of 100 × 100 mm. Using ordinary unplaned material, you will still have to resolve issues with facade cladding and interior decoration, dealing, for the most part, with the problems of the aesthetics of the result. But for permanent residence it is better to use profiled timber with a width of 150 mm. In this case, you will still have to insulate the walls. As for the thickness, everything is simpler: it just determines the number of beams needed to build the walls. But, meanwhile, this also affects the number of seams between the crowns. To summarize the above:
- the thickness and width of the timber for a country house is practically unimportant (for seasonal living in the warm season);
- For permanent residence, you can choose a larger width, but you will still have to insulate the walls. Or you can save on cubic capacity by relying on high-quality insulation - it will be cheaper and more effective in terms of reducing heat losses.
So, in order to build a truly warm house without insulation, the thickness of its walls for the Moscow region should be about half a meter. The same effect will be achieved when using 150 × 150 timber and 10–15 cm of thermal insulation.
We draw your attention to the fact that not all manufacturers and sellers of lumber are honest with their customers: you can often encounter an underestimation of the declared cross-section. For example, a 150 × 200 beam actually has a cross-section of 140 × 190 or even less. Be sure to check the actual parameters before purchasing! This will help you avoid getting into trouble, save money and nerves!
Estimate
Before deciding on the choice of builders, start monitoring proposals. To determine the most economically feasible option, ask different competing companies for their estimates for the selected standard or individual project, which includes all costs: both the cost of building materials and fees for performing all types of construction work.
Regular companies offer such estimates for free. It is noteworthy that for different companies, the total amounts for the same buildings can differ not only by 10–20%, but also several times. It is advisable to have on hand the most detailed list of works and materials to implement your idea - this is the only way you can avoid additional, unforeseen expenses along the way.
If desired, the estimate can be drawn up independently: by calculating the consumption of materials, multiplying the results by average prices (in total these will be the costs of building materials) and adding on top approximately 50–100% of this amount to pay for the work. Such an approximate calculation can be used to analyze offers from specialized companies.

In order for the calculator to calculate the costs of materials, certain parameters of the future home must be entered into its form. You need to roughly imagine what the frame of the building will be like, its roof, what type of foundation it will be.

Posts and walls
The racks in a single structure form the frame of the building. They are constructed from timber, beams and boards. Beams and beams are produced in several basic sizes. The height of the racks is determined by the height of the building. The distance between the racks (step) depends on the selected type of panels for sheathing and insulation.
To build walls you will need a whole set of tools, as well as screws, hardware and other tools. All this is taken into account in online calculators, which allow you to approximately calculate the material for a frame house.

Insulation
Insulation is an important element in the design of a frame house. Therefore, many calculators have a separate column for taking into account the thickness or type of insulating material. As insulation, you can use the most economical polystyrene foam or, for example, very expensive but effective ecowool. But usually private developers use an intermediate option in the form of glass wool or mineral wool. In a two-story frame house, the interfloor floors are sometimes insulated using bulk insulation.
In order for the insulation to last a long time, it is necessary to provide a layer of waterproofing and good ventilation. The more complex the insulation and ventilation system of a house, the more comfortable and durable the home will be, and the more consumables need to be taken into account.

How to calculate the volume of cubic capacity of a rafter system?
Everything is more complicated here - a lot depends on the angle of the roof you plan to build. Accordingly, we will not provide exact calculations with examples. But you can do it yourself, because the technique is simple:
- we calculate the length of the rafter leg for a roof with an angle of 45 degrees - this is the sum of the squares of the legs;
- we determine how many 6-meter blanks will be needed to build one triangle;
- multiply the resulting value by the number of triangles that will hold the roof;
- multiply this figure by 0.135 (for timber 150*150) and get the volume of cubic capacity.
Timber must always be purchased with a reserve, because it has to be increased during construction. Also, a lot is spent on trimmings, so it’s better to take an extra 10-15%.

About foundations for a frame house, watch the video:
The foundation, as well as the frame and roof of a cottage, can be calculated using a calculator. To do this, you need to find an online program specifically designed for foundation calculations. However, if such a program is not used by a specialist, he may enter inaccurate data and receive erroneous calculation results. Therefore, it is better to additionally consult with a qualified builder regarding the foundation.
The influence of the pitch of the racks on the cost of the house
The smaller the distance between the posts, the greater the consumption of materials for building a house. In addition, with a small step, the structure turns out to be quite labor-intensive to construct. On the other hand, too large a step makes the building unreliable, and the use of some insulation and insulation materials is impossible.
It is very important to choose the spacing width of the racks correctly. Experts recommend choosing step parameters ranging from 50 to 70 cm. In any case, the racks should not be placed more than 1 meter apart from each other. With this step, the house will be stable and durable, and when covering it, you can safely use convenient and inexpensive standard materials.
There are online calculators that can be used to separately calculate the racks for a frame house. They need to indicate the material of the rack and the type of its section. For preliminary calculations, using such a program may be too complicated, but very informative.
