How many cubes of lumber do you need for a 7 by 8 house:

To answer the question of how much material is required, including the timber itself, if you are going to build a house from timber 7 by 8, everything must be calculated. And proceeding not only from the proposed size, but also from the design features of the structure.

House of timber, types and calculations

To begin with, it is necessary to determine how much you can talk about the diversity of projects of such houses.

For this, the following classification is given:

• Single-story building. A simple house, small and more suitable for country construction.
• House with attic. Интересный и рациональный вариант, который позволяет рационально подходить к использованию полезного пространства.
• Two-storey house. Современные технологии производства древесины позволяют строить дом в два этажа.
• Three-storey house. This is a rare but right to life option.

Floors, the standard part, which projects of houses from timber 7 by 8 are always taken into account, and which has the most direct impact on the amount of material needed.

Cottage

Let's start, perhaps, with the simplest version of building a house, and this simplicity will be expressed in everything, both in estimates of estimates, and in calculations of the material, and in work, if we are talking about independent construction.

In any project, regardless of the height, the perimeter of the house remains unchanged. In the case of the proposed option, the perimeter is calculated as follows: all sides of the house are folded, that is: 7 + 7 + 8 + 8 = 30 meters.

Note! In construction, you can always find, find several ways to count the materials, so that the perimeter is sure to come in handy.

Next, you need the parameters of the house and the parameters of the material for accurate calculation of the cubic capacity.

Schematically, the requirements can be described as follows:

• The required height of the walls of log houses. There is no standard here; in private low-rise construction, everyone is free to choose his own height. However, there is averaged version - 3 meters.
• The cross section of the material, the project of the house of timber 7x8, in the version of one floor, is 150x150 mm.
• The number of windows and doors.

Note! The moment with window openings always causes a lot of disputes, because they must be taken into account when calculating the volume of necessary material. It can be considered, or one can simply “give” 20% to windows and doors.

How to calculate a one-story project of a house from timber 7 by 8 by cubic capacity? All the values ​​that are already known are multiplied, length, height, thickness, and it turns out: 30 * 3 * 0.15 = 13.5 cubic meters of wood will be needed for the box at home.

In principle, by exactly the same principle, it will be possible to calculate window and door openings, and it is even necessary to accurately calculate the cubic capacity.

In low-rise construction there is no standard window opening, it may be a small window, or almost a stained glass window, however, for the example of calculation, a window opening 1.5 meters wide and 1.9 meters high is proposed.

Considering that there is a material thickness value, we get the calculation: 1.5 * 1.9 * 0.15 = 0.427 cubes. The doorway is considered the same way.

It turns out that the box for a one-story house will require 13.5 cubes, excluding window openings.

House with attic

Interesting projects of houses from a 7x8 lumber with an attic always act as the most rational option for building a house.

There are several prerequisites for this:

• With a constant perimeter, the developer gets the opportunity to increase the total living space.
• The general estimate of construction costs is reduced, because the walls of the attic, the side walls, are immediately a roof.
• On the gable less material is required than on the full second floor.

Such projects of the house from timber 7 to 8 allow rational use of at least three components of the construction process:

• Financial expenses. Roofing is always expensive.
• The amount of wood required.
• Energy costs when it comes to building on your own.

In working with gables, the question of cubic capacity naturally arises, because here completely different formulas for calculating work. If you calculate the area of ​​the gable, then you can calculate the cubic capacity.

In this case, the calculation is made according to the formula

So in the case of an example of a house, the gable looks like this:

• The base of the gable is 7 meters.
• Height -4 meters.
• Area - 14 square meters.
• Now 14 m is multiplied by the cross section of the beam: 14 * 0.15 = 2.1 cubic meters of timber.

Naturally, all these calculations allow us to obtain the required cubic capacity just as a “pure” figure. What is meant by this? Lack of counting on window and door openings. However, this is a purely personal matter of each developer, whose windows can be arranged in any number and size.

In any case, the instruction for calculating the cubic capacity is clear, as is the fact that it is always necessary to buy 10-15% more material than is necessary.

In the case of the attic version, it is 13.5 cubes of the box, and 4.2 cubic gable. The roof is not considered, there is another system. Total = 17.7 + 10% = 19.4 cubes.

Two-storey house

There are no problems at all with the calculations for the two-story construction. The cubic capacity of the first floor box is simply multiplied by two, and that's it. In this case, a two-storey house of 7x8 glued timber, it is 13, 5 * 2 = 27 cubic meters of timber.

Note! All calculations are carried out, given that the cross section of the material is 150 mm. If you select a different section, you just need to change one of the parameters of the calculation formula.

Constant talk about the fact that you always need to buy material at 10-15% more, causes a lot of questions from an inexperienced developer, so you can give a few explanations for why this should be done, especially with regard to the house from a bar:

• Wood must be the same moisture. The difference in humidity can lead to the fact that the walls will begin to be “led”, and this deformation is quite a serious level.
• In the course of work, there is always a chance to spoil a couple of beams, to cut off not to size, to cause a bar to be defective.
• If there is no additional finishing of the timber after construction, then the exterior of the wood structure, color, should be harmonious.

Cost of

How much does the total cubic capacity of timber on the cost of the house? Directly and indirectly at the same time.

The fact is that in order to calculate how much a house costs from a 7x8 bar is not enough just a cubic capacity, the full calculation is carried out on the basis of:

• The total volume of the total material, and this box, and partitions and interfloor overlap.
• The cost of the foundation. And this can be both a fairly inexpensive version of the screw base and an expensive monolith.
• Roof costs. Here not only the price of roofing materials is taken into account, but also the cost of the work, it is better to entrust the roof to professional builders.
• Finishing work, both external and internal.

Of course, cubic capacity matters, and the price of a single cube has a definite impact on the value of the entire house, but in order to calculate everything, the estimate needs exactly the complex.

To some extent, to reduce the overall figure on costs, allows independent work on construction.

Everything to build, is unlikely to succeed, but there are a number of works that you can definitely do with your own hands:

• The foundation for the construction of the house of timber. And of any type, you can prepare and pour on their own.
• Box home. A tree, especially profiled, is a material with which it is fairly easy to work, so it is not difficult with exact recommendations to build a box and the first and second floor.
• Finishing work. Grinding, for example, is a fairly simple job, like paintwork.

Conclusion

Provided that all recommendations are accurately followed, and most importantly, the design capacity for the construction of a timber house, it is possible to initially calculate everything accurately, and carry out construction without being distracted by additional purchases of material.
