Projects of houses from a bar 7х8 with a mansard: the

Buildings of profiled wooden timber in recent years enjoy significant popularity. To understand the reasons for this popularity, in our article we will analyze a typical project of a house from a 7x8 bar with a mansard and clarify for itself its pros and cons.

Analysis of a typical project

Material used

For the construction of residential houses, timber is very often used - a material obtained by cutting a piece of wood from a tree trunk.

According to the configuration, the beam is divided into:

• Normal - has a quadrangular shape (rectangle or square). The production technology ensures a uniform thickness of the entire billet, which greatly simplifies installation.
• Profiled - available with ridges and grooves of different geometry. The complex configuration increases the cost of production, but at the same time the connection between the bars between them is as tight as possible. Moreover, with certain skills, you can even assemble profiled elements with your own hands.

In addition, an important factor in choosing the material from which the house will be built is its structure:

• A solid timber is sawn from a log, and therefore has both advantages and disadvantages of natural wood.

Note! The main disadvantage of solid blanks - uneven density and the presence of hidden bundles. In addition, the shrinkage of solid wood products is very significant.

• Glued - made from planks, which are connected in such a way as to avoid coincidence of the fibers. Glued varieties of timber have greater strength, resistance to deformation and retain heat better.

For the construction of houses with an attic most often used precisely glued profiled material. The use of other varieties can reduce the cost of the project, but its operational properties will be reduced.

Project Features

At the moment, the market can find a lot of typical projects of such houses. The dimensions of 7x8 or 7x9 m are one of the most popular, since they provide sufficient living space with a two-story configuration. At the same time to build such a structure can be on a relatively small area.

Usually, the instruction contains the following recommendations for the construction of a log house with an attic:

• The foundation is a columnar construction of concrete blocks. It is possible to build a house on the basis of a tape type, but this will entail large costs.
• The walls are made of profiled glued material (base - spruce or pine wood). The section of the blanks is 100x150 or 150x150 mm. Antiseptic wood impregnation allows you to avoid additional exterior trim.
• As a heat-insulating material fit jute mezhventsovy insulation. The connection of the bars occurs with the help of metal dowel rods.

Note! To improve energy efficiency, metal pins can be replaced with wooden ones, but in this case the project price will increase somewhat.

• The second floor has a combined construction: we lay out 8-10 crowns from a bar, and then the gable parts on which the roof rests are made using frame technology with cladding. Between the cladding panels lay insulation - mineral wool.
• Interior partitions are also made of solid wooden blanks (optimal size - 50x50 mm). To increase thermal insulation and give a more aesthetic look, the bar is sheathed with clapboard.

As for the configuration, in most of these projects there are several residential premises and a bathroom with a kitchen on the first floor, as well as two or three bedrooms on the second floor. Depending on the wishes of the customer, changes may be made to the project (also read the article How projects of houses and cottages are made of timber).

The living area of ​​the resulting building is within 100m². Perhaps for a family with children that is enough.

Advantages and disadvantages

Arguments for"

The analyzed project, as well as similar ones (for example, a house from a 7x7 bar with an attic, which is not too different in construction) has quite obvious advantages:

• The first and most important thing is, of course, the material itself. High-quality timber, which is made from coniferous wood, has high performance characteristics both in terms of strength and in terms of energy saving.
• The construction of the walls of this house provides reliable protection from heat loss. At the same time, to achieve similar indicators of resistance to heat transfer, the project of a 7x9 house with a mansard from a bar provides walls 40% thinner than the rear of a rounded log.

• Shrinkage of buildings when assembling from properly dried material will be minimal. Since, after shrinkage, the caulker is not required, the speed of construction of the structure increases, and quite significantly.

As for the cost of building a house for this project, it can be considered acceptable, especially for buildings of this class. On average, the construction of the building "under the roof" will cost 7500-900 thousand rubles. depending on the material used.

Arguments against"

What swing minuses, in most cases they are not due to the features of the project or material, and the negligence of the performer.

So, even if you do all the work yourself, it is very important to pay attention to such moments:

• Impregnation of wood. Attempts to save money by buying billets cheaper, very often lead to the fact that the building starts to rot in just a couple of years after construction.
• Material type. Glued profiled timber is more expensive, but it differs in the best indicators of heat saving. One-piece products will help save on building a building frame, but all the savings will be negated by the cost of thermal insulation.

• The disadvantages of such projects also include the construction of the attic. The fact is that the execution of the upper part of the gables on frame technology leads to an increase in heat loss.

However, with a responsible approach to work, all these shortcomings can be taken into account in advance and their impact on the final result can be minimized.

Conclusion

Projects of houses from a timber 7x9 with an attic and similar should be considered if you need to build a comfortable suburban housing. This design option can not be called neither the cheapest nor the simplest in execution, but the obvious advantages of log houses often become a decisive argument in their favor (find out here how you can use unplaned timber).
