Dome houses: projects and prices. Description and recommendations for construction

Dome houses in our country are not widespread and are not used in mass construction. However, for those who are inclined to implement their most daring ideas and ideas, this project can be a great way to build an unusual house. Of course, such construction has its own specifics. The article will consider what domed houses are: projects and prices, as well as a description of the structures and photos of the original buildings.

The domed house not only looks unusual, but also has a number of advantages over traditional buildings.

What are domed houses: projects and building prices

Dome-type houses are a rarity in our area, and they are rarely seen on city streets. For this reason, not much is known about the advantages and disadvantages of such structures and how justified their construction is in comparison with traditional buildings.

Domed houses are rare in our latitudes.

Among the positive aspects of the construction of such unusual houses are:

• the interior space of domed houses is used more rationally. First of all, this can be noticed if you make calculations of two houses that are the same in area, but have a different shape (domed and square). In the first case, the savings in building materials will be about 20%;
• in comparison with domed, rectangular houses are less resistant to mechanical stress, including wind. By itself, a hemisphere can withstand much more, of course, if all calculations have been made correctly;

Note! A domed house built in accordance with all norms and rules is able to withstand even a strong earthquake and not collapse. However, for this, it must have a solid foundation and high build quality.

Subject to compliance with all the rules and regulations of construction, the domed house can become a reliable and durable structure

• flat roofs are already not very popular in our climatic zone, however, the domed shape of the roof will completely save you from the need to remove snow from the roof;
• the number of windows that can be provided in a domed house without reducing the strength of the structure is much greater than for standard buildings;
• due to its shape, the domed house can be located on the site with absolutely any side, and the load will always be distributed evenly.

Triangular or oval windows are best suited to the design of a domed house

Among other advantages, it is worth noting that due to the lighter weight of the entire structure, it does not need such a massive foundation as for traditional buildings. A not too expensive and complex tape base will be enough. In addition, the assembly of the structure is made from ready-made elements, so it takes only a few days.

Among the disadvantages of such designs, the following nuances are noted:

• if you have construction in a small or narrow area, it is convenient to place a round-shaped structure can be difficult;
• the arrangement of furniture in a finished home can also cause some difficulties related to the shape of the house. It is unlikely that you can put something against the wall;

Using the unusual shape of the house, you can create interesting interior design solutions

• the construction of such a structure implies non-standard execution of some of its parts, which may entail additional costs;
• It is difficult to create a project of a domed house on your own. You can use ready-made drawing or order an individual development using 3D technologies.

It is also worth understanding that standard windows in domed houses are of little use. Round or triangular windows that will organically fit into the overall image of the house are much more suitable.

Helpful advice! If you want to build a sphere house, you can find projects of spherical houses of a suitable size on the Internet, or contact a company that manufactures and assembles them.

Dome houses: projects, design features and its construction

In order to give the house a domed shape, a special power frame is used, on top of which a protective and decorative coating is mounted. The inner part of the walls must be sheathed with insulation. At the same stage, they are engaged in laying network cables and other communications.

The erection of interior partitions and the installation of door and window openings is carried out using standard technologies that are also used in buildings of traditional shape.

To provide the frame elements with a reliable connection, special fasteners are used, which are called connectors. Since it is they who take on all the main burden from using at home, their choice should be given special attention. It is necessary to choose and buy connectors for a high quality domed house and not save on the purchase.

In order for the house in the shape of a sphere to serve as long as possible, you should not save on the quality of materials

If you are planning to build a house on your own, the area of ​​which will be from 150 to 250 m², then it is recommended to use a steel blank with a thickness of at least 3-4 mm.In most cases, this is sufficient, since such buildings rarely have more than 2 floors, and the load is distributed in such a way as not to have a destructive effect on the frame.

Spherical houses: projects and materials for construction

In the process of building spherical houses, as a rule, preference is given to lightweight, environmentally friendly and durable materials. In addition, they should be easy to install and at the same time fully fulfill their role. Consider the components for spherical construction:

• connectors for a domed house are elements that provide the structure with strength at the points of nodal connections. In order to protect these areas from corrosion, they are additionally opened with a primer and paint;
• an insulating layer is required, which is most often used as mineral wool. However, there is another option - polyurethane foam. It is easier to install and, unlike mineral wool, does not allow moisture to pass through, which greatly facilitates the work;

When building a house-sphere, environmentally friendly natural materials are most often used.

• OSB is used as a substrate for the roof, which belongs to category 3 or 4. For their production, wood chips are used, which are pressed and fastened together using synthetic resins. Such slabs are strong enough for this purpose and extremely resistant to heavy loads;

Note! Previously, OSB boards were not recommended for use in the construction of residential premises, since they tended to emit formaldehydes that are unsafe for humans. However, today, in the process of their manufacture, only the most modern materials and technologies are used, which completely eliminated such risks.

• flexible shingles are used to decorate the upper part of the roof, since this is the only material that easily takes any shape and at the same time is simple and quick to fit;

The layout of the interior of the domed house

• the layout of domed houses can be any. Using, for example, sheets of drywall, you can divide the available space as it will be convenient;
• a wide variety of materials can be used for interior decoration. To create the original interior of the domed house, you can use any available materials, combining and combining them at your discretion.

As you can see, all the materials that are used for the construction of domed houses are lightweight and extremely easy to install and dismantle. Therefore, the finished house can always be disassembled, transported to another place, and reassembled without damaging the structure and completely preserving all the characteristics of the building.

Features of the layout of the domed house: photos and recommendations

Of course, the layout of the domed house will be somewhat different from what we are used to. However, this does not mean at all that the unusual shape of the building imposes any restrictions or prohibitions on the owners. On the contrary, thanks to the unusual shape of the walls, you can create the most unusual and original interiors.

The interior design of the domed house will differ from standard solutions

Here are some tips to help you with your arrangement and decoration:

• Since all furniture and decorative elements are designed to be placed against a standard wall, you can think about individual customization. For example, semicircular paintings placed on the wall look great;
• if you need to furnish the office, you can think about wooden furniture, the elements of which will exactly repeat the shape of the walls, giving the room an unusual atmosphere;
• as for the installation of various communications, only the shape of the inner walls, as well as the features of the finishing materials used, will play a role;

To create a harmonious atmosphere in a spherical house, it is better to use several light sources.

Helpful advice! Some builders recommend using straw for wall insulation. You can learn how to make a domed straw house on specialized sites and forums.

• an element such as a fireplace can be placed in the center of the room, making it the main element of the composition and at the same time solving the problem of the absence of a flat wall for its installation. In addition, this will allow you to maintain the maximum amount of heat that it gives without wasting it on heating the outer walls;

• another problem that can arise is opening windows. If they are located high enough, then manually opening them will be simply inconvenient. For this purpose, there are automated systems that allow you to do this using electric drives;
• special attention should be paid to the lighting of the domed house. It will be better if there are many light sources, because if you use one traditional chandelier under the ceiling, light may be lacking.

One of the most successful options for placing a fireplace is in the center of the room

Dome house: photos, projects and technical features that need to be considered

In addition to the features that owners have to face in the process of arranging a domed house, it is also necessary to take into account a number of requirements that apply to any residential building. So, the project must necessarily be drawn up taking into account all fire safety standards, as well as in accordance with the construction rules.

The terrain and type of soil on which the building will be erected must be taken into account. An important role is played by the level at which the underground waters are located, because, despite the relatively low weight of the structure, it is still a residential building that must stand firmly and over time not succumb to external destructive factors.

Of course, in the construction process we strive to use the most natural and environmentally friendly materials. But when it comes to the implementation of such a non-standard project as a domed house, you should pay attention to modern artificial materials. In many cases, they surpass natural counterparts in a number of technical characteristics.

Finishing the facade of the domed house with natural stone

It is worthwhile to think over the heating and ventilation systems, since their arrangement has certain nuances, and in order to economically allocate resources, it is important to study this issue in advance.

Helpful advice! In order to get an up-to-date list of norms and requirements, you can contact a specialized organization. Moreover, there you can get information about typical domed houses and see their photos and projects.

How to build a domed house with your own hands: instructions for assembly

In order to build a solid and reliable domed house, it is necessary to strictly adhere to the proposed algorithm, performing each operation step by step. Consider every step from laying the foundation to finishing your home.

As with the construction of any traditional house, it is necessary to start with measurements and equipment of the appropriate foundation, which will become a reliable basis for the structure. After that, the main elements of the frame are laid out, which will perform a load-bearing function and are the basis of the whole house.

You can create a spherical house with your own hands, or you can turn to specialists or buy a ready-made package

Using a wooden hammer, it is necessary to drive the dowels into the supporting vertical beams. The strength of such a connection is ensured by the elements' own weight. For this reason, construction is progressing extremely quickly, especially considering the fact that special grooves are provided in the lower parts of the boards.

After that, you can proceed to the installation of cross braces and fixing the OSB board. For this purpose, standard self-tapping screws are perfect, which will provide fast and reliable fastening.

At the top point, where all the beams converge, a special disk is used for reliable fastening. At the same time, the sheathing of the lower segments is carried out, which gives the structure additional stability and strength. After that, it remains only to install the upper struts and sheathe the frame with wood boards.

Acting according to this scheme, it is quite possible to carry out the assembly yourself, instead of purchasing a ready-made domed house. The owners' reviews claim that if you strictly follow all the recommendations, then in the end you will get an equally durable structure that will last you more than one year.

Not everyone wants to build a house on their own, and many prefer that specialists implement a finished project of a domed house on their site. This option is less risky, since it excludes the most difficult stages of preparation, and the calculation of the domed house is reduced only to taking into account the existing conditions.

But before ordering a turnkey dome house, it will be useful to familiarize yourself with as many offers in this area as possible. Projects and prices of spherical houses can differ significantly from each other, which, on the one hand, significantly expands the choice, and on the other, complicates the task of choosing the best option.

As for the price of a turnkey domed house, it is important to understand that in addition to purchasing the frame itself, you also need to take into account various indirect costs that, one way or another, will arise during the construction process.

Buying a domed house may not be as profitable as building it yourself, but you get a warranty from the manufacturer and in case of any problems, you can easily turn to him for help. As an example, consider several options for domed houses, their prices and main characteristics.

Stratodesic dome house: cost and features

A stratodesic dome house is a structure that is assembled from individual vertical posts assembled at the top point. Such structures differ from geodesic domes, since if, in parallel with the assembly of the frame, partial cladding is not carried out, the house will not have the necessary stability and it may simply fold.

When building a small house of about 52 m², complete assembly takes only a few hours. However, taking into account all additional finishing works, this can take up to 7 days. At the same time, the purchase and assembly of the frame will cost about 500 thousand rubles, excluding internal finishing work and the purchase of the necessary materials.

Helpful advice! Be sure to read the reviews of the owners of domed houses.This technology has not so long been used in our region and, perhaps, on thematic forums and sites you can find useful information and practical advice for construction.

Dome houses using Japanese technology

The Japanese technology for the construction of domed houses implies the use of not only non-standard solutions in the process of assembling the frame, but also the use of materials that are non-traditional for this type of building. This technology makes it possible to build domed houses from polystyrene foam, which has excellent thermal and sound insulation properties, while having a very low cost.

Depending on the peculiarities of climatic conditions, for the construction of a domed house made of expanded polystyrene, material of various thicknesses (from 8 to 19 cm) is used. The frame is assembled from separate sections, which already have door and window openings.

Installation of the entire structure can be carried out as on a conventional strip foundationand on a wooden frame. The only difference will be in the way the house is attached to the base. All communications are laid in the internal partitions of the house, and in the presence of several floors, in the ceilings.

The main advantage of domed houses built using Japanese technology is high mobility and at the same time sufficient reliability to build such houses even in our rather harsh climate. According to reviews, domed houses, with proper finishing and insulation, are in no way inferior to traditional buildings in technical characteristics.

When familiarizing with the projects and prices of domed houses made of expanded polystyrene, you will notice that their cost may differ significantly. This depends not only on the materials used, but also on the company itself, which produces and sells the sections. The minimum cost will be 2000 rubles per 1 m², however, this depends on how thick the walls will be and what materials will be used.

Looking through photos of domed houses, projects, as well as instructions for construction, you can make sure that such an original idea as a spherical house is worthy of attention. At an affordable cost, such a structure is very easy to erect, resistant to any external factors and is in no way inferior to traditional houses. And in order to do everything yourself, without resorting to the help of specialists, it is enough to watch thematic video tutorials.
