Wooden house one and a half floors. The design of the mansard roof of the house in one and a half floors. Varieties of mansard roofs

The choice of the number of storeys of a house is a rather complicated and responsible issue, which should be taken with all seriousness. A one-and-a-half-story and two-story house has its own individual characteristics that must be taken into account during construction. Therefore, it is important to familiarize yourself with them in advance.

The main differences between the attic floor and the second

There are differences that distinguish the two types of buildings that make them so different.

• First of all, it is worth noting the cost. The construction of a one-and-a-half-story house will be relatively lower than that of a full-fledged second floor. The shape of the roof and the type of roofing material will also affect the price.
• In terms of execution time, the attic floor can be built much faster than the second floor and roof.
• The load on the foundation of the first option is lower, which saves on the construction of the foundation.
• In the attic floor, rooms are obtained with a smaller usable area, since the height of the walls does not exceed 1.5 meters.
• In the attic it is possible to make skylights, due to which there will be much more light in the room.

These differences determine the choice of building. Each option has its pros and cons, the decision remains with the owner of the future building.

Features of a two-story house

A two-story building involves the arrangement of a full-fledged floor and an attic space. With such construction, it is worth considering the load of the walls and roof on the foundation. The base must be sufficiently strong and massive. The height of the ceilings throughout the entire area of ​​​​the room is the same and allows you to distribute furniture as desired. The attic can, in turn, be used for any economic purposes.

Pros:

1. more usable area;
2. the attic can be equipped to store seasonal items.

Minuses:

1. requires the arrangement of a more powerful foundation;
2. higher cost.

A full-fledged second floor is considered if the height of the wall exceeds 1.5 meters. This is the main characteristic that distinguishes the attic floor from the second.

Distinctive characteristics of a one and a half-story house

Today, such buildings are very popular, due to the fact that they are quite economical in terms of construction costs. At the same time, they fully provide people with living space. According to the norms, a semi-attic floor is considered if the height of the walls does not exceed 80 centimeters. A full-fledged attic, according to the norms, should have walls with a height of 80 centimeters to 1.5 meters. The roof acts as a ceiling in such a room, but there is no attic.

Such a living space is most often used for arranging bedrooms and children's rooms. It looks very impressive when the windows are not located on the walls, but directly on the roof. Angled windows let in much more sunlight. In order to minimize noise from rain and other precipitation during the construction of the roof, it is very important to pay special attention to sound insulation, for this purpose it is necessary to use special insulating materials and sheathing with general construction sheet (with subsequent finishing) or immediately with decorative materials.

Some difficulties may arise when arranging furniture, since the outer walls will be much lower than that of a full floor. This problem can be solved by making furniture to order.

The advantages of a one-and-a-half-story house also include relatively low weight, since the walls are much lower, and there is no overlap between the second floor and the attic. This reduces the load on the foundation of the house.

Which house to choose

The choice will depend primarily on the personal preferences of the developer (owner). The main thing is to first familiarize yourself with all the characteristics of the two buildings in our catalog of country houses. Both options are great for residential construction. And they can fully satisfy all the needs of every resident of the house. Also, the choice may be influenced by financial aspects and the ability to carry out turnkey construction or perform all the work on their own.

It is advantageous to build a frame house of one and a half floors on a small plot. It has all the advantages of a two-story cottage, but is cheaper. Due to the vacated area nearby, you can build a garage. Such houses are suitable for permanent residence, well maintained in the winter.

The construction of a house of one and a half floors is carried out by building up the attic walls above the first level. Such a building does not have an attic, because it becomes part of the living space and is constantly in use. The house can be equipped with a cuckoo, a balcony, a bay window or other small forms of architecture - it all depends on the approved project.

We have compiled for you a convenient table of differences in the configuration of houses for shrinkage and turnkey.

First you need to figure out what a house of one and a half floors is. This is a house with an attic, that is, the top floor of such a building has a smaller area, which is reduced due to the slopes of the roof. Since the walls are not understood to the height of the attic floor, the roof in a house of one and a half floors simultaneously performs the functions of walls, that is, it must not only protect against precipitation and effectively drain rain and melt water, but also perform the functions of enclosing structures, reliably protecting the room from cold and noise.

First you need to figure out what an attic is. In fact, this is a living space located in the attic area and formed due to the slopes of the roof. It is advantageous to build houses with an attic for aesthetic and economic reasons. The advantages of such buildings include the following:

1. Without spending money on the construction of a full-fledged second floor, the owners receive additional living space.
2. The time for building a house with an attic is less than the time for building a full-fledged two-story house with the same living area.
3. The attic floor can be arranged in an already inhabited house. At the same time, you do not need to move out of it during the installation of the attic.
4. With the right arrangement of the attic, you can significantly reduce the heat loss of the building as a whole.
5. Attic houses allow you to increase the building density, which is important where the amount of land allocated for housing is limited.

Important! Attic can only be called a room in which the horizontal line of intersection of the slopes and walls is from the floor of the upper floor at a height of at least 1.5 meters. Otherwise, this space is called an attic.

Varieties of mansard roofs

A house of one and a half floors can be covered with a different roof. In many ways, the shape of the attic room depends on the type of roof chosen. The attic floor itself can have a triangular, asymmetric or broken shape. At the same time, it can be located both above the entire area of ​​\u200b\u200bthe house, and above its separate part.

For houses with one and a half floors, the following types of roofs are suitable:

1. The simplest option is shed roof. This is an ordinary inclined plane, which rests on two opposite load-bearing walls of the building.
2. Gable or gable design is used most often. It is quite reliable, easy to install and consists of two slopes going in different directions from the ridge.
3. A broken roof is a type of gable system. Usually this option is used in small structures. It is ideal for arranging the attic, as it allows you to maximize the usable area of ​​\u200b\u200bthe room.
4. Half hip and hip design are a type of hipped roof. If we talk about a semi-hip roof, then it is more suitable for arranging an attic, since it allows you to make two vertical windows in the end walls under shortened hips. Under the hip roof, the area of ​​the attic floor will be much smaller than the area of ​​the first floor.
5. Pyramidal, domed and conical roof are also suitable for these purposes, although it will be more difficult to equip an attic under them.

Design features

In constructive terms, all attics can be divided into several varieties:

• single-level system under a broken or gable roof;
• single-level attic with remote consoles;
• two-level construction on mixed-type supports.

Attention! When choosing a type of roof for arranging the attic floor, be guided by the intensity of snow and wind loads on the roof surface.

When arranging a mansard roof, the following requirements must be considered:

• When choosing building materials and a design scheme, it is necessary to take into account the parameters and characteristics of the building as a whole.
• It is important not to forget about the illumination of attic rooms. To do this, you can use dormers and dormer windows, as well as ordinary vertical windows in the walls under shortened hips. When choosing the location of windows, it is worth considering the architectural appearance of the building.
• Do not forget about the stairs with which you can get to the attic. It should be inside the house, have a normalized slope and be safe.
• With special care, you need to approach the choice of roofing, heat-insulating material for the roof, waterproofing and sealing all joints and cracks.

If the roof slopes intersect with the walls of the house very close to the floor level of the attic floor, then the rafter gap is sewn up with light structures to the standard height (1.5 m). The space behind the vertical cladding can be used to organize storage areas.

Worth knowing: the width of the structure in which it is planned to equip the attic should be at least 4.5 m. The minimum area of ​​​​the attic floor is 7 m². The ratio of height to usable area should be 1 to 2.

A broken mansard roof is made if the dimensions of the room do not fit into the triangle, which is formed by the usual gable design. With a broken option, you can reduce the unusable area that will be hidden behind the side lining to the required height.

The optimal attic height is 2.5 m. When using a sloping roof, it is easier to achieve the required parameter. In any case, it is important to remember that the greater the angle of inclination of the roof slopes, the higher and more spacious the attic will be. The optimal slope angle of the truss system in this case is approximately 45-60 °.

Roofing pie mansard roof

In order for the living space under the roof to be warm and quiet, the following layers should be provided in the design:

1. A vapor barrier film must be attached to the bottom of the rafters. It will not allow condensation to accumulate in the heat-insulating material due to the temperature difference in the house and on the street.
2. Thermal insulation material is laid between the rafters. To keep the attic warm, you need to lay a heater with a thickness of 200 mm. If the height of the rafters is not enough for this, a beam of the desired section is nailed to them from below.
3. Waterproofing is necessarily attached to the upper edge of the rafters with the help of a construction stapler. It will not allow rain and melt water to penetrate to the supporting frame and insulation.
4. After the waterproofing carpet comes the counter-rail. It is needed to form a ventilation gap, which is especially important for mansard roofs. A rail with a height of 30-40 mm will ensure ventilation of the space between the waterproofing and the roofing. It is nailed directly to the rafters over the waterproofing carpet.
5. After the counter-rail, a continuous or sparse crate is performed. Its choice depends on the type of roofing used. So, under roofs made of soft rolled materials (for example, flexible tiles), a continuous crate made of boards, OSB or moisture-resistant plywood is equipped. The sparse crate is made from a board 0.25 cm thick and is suitable for corrugated board, metal tiles, ondulin. If the coating is heavy enough (slate, natural tiles), then a continuous crate is made along the cornice overhangs, in the area of ​​\u200b\u200bthe ridge, valleys and roof ribs.
6. Roofing must be selected taking into account the climatic features of the region, the slope of the roof and the requirements for the room.

Important! In an attic covered with metal tiles or profiled sheets, it can be too noisy during rain and hail. It is worth considering this fact if you plan to place a bedroom there.

It is also worth remembering that the ventilation space that is formed by the counter-rail will only be effectively ventilated if appropriate aeration holes are left under the front ridge element and at the bottom of the eaves overhang.
