Projects of spherical houses. Domed house: construction technologies and planning features Domed house pros and cons

For a modern resident, the construction of a private building is considered an attractive prospect. This is an opportunity to get out of the stuffy city, live on your own plot, raise children in environmentally friendly and natural conditions for humans. What do you know about spherical dome houses?

Dome houses, projects and prices

One of the unusual types of buildings is called sphere houses, another name is geodesic houses. Although they appeared on the modern construction market around 2008, they cannot in any way be classified as inventions of modern architecture.

Round-shaped buildings with domes were built back in Old Byzantium. Although, as a rule, this form of apartment was preferred by residents of northern countries, for whom the issue of heating a building in winter was too acute.

Who invented the geodesic (dome) structure and why? Richard Buckminster Fuller, philosopher, mathematician, engineer, historian, poet. In 1951 he invented and patented the geodesic dome.

Many companies in Russia have mastered the technology of creating domed buildings, so buying such a house that suits your requirements is not a problem. You can understand what domed houses look like from the following photos.

A dome structure created for human habitation solves the problem of creating a convenient structure that allows it to prevent exposure to adverse environmental factors. There is a positive energy balance here. Everyone who has managed to live in these houses says that being in the building evokes a feeling of lightness and grace.

Aerodynamic design can enhance a home's resistance to strong winds. Such a structure will be resistant to seismic influences; according to the calculations made, it will calmly withstand vibrations of the earth’s crust with a force of up to 10-12 points.

Even experienced builders are often interested in the question of how to calculate a domed house and what its cost is. It is impossible to answer definitively, since the design process may require additional extensions, various finishing methods and materials. However, it will help to quickly calculate the basic structure. Taking into account the way in which the ribs are connected, their cross-section and the radius of the base circle, it is possible to obtain information about the number of types and number of vertices, edges, faces, their sizes, the structural diagram of the dome, sections of the diagram at the ends of the ribs, drawings of faces, edges of nodes.

Design features of a dome house

Usually, when drawing up a project, a standard structure with a diameter of 8.1 meters is calculated. This size is used when developing standard and private projects.

With a dome radius of 8m, the house has a base area of about 153 m2 and a ceiling height of 7m! What other two-story building, with an area of about 300 m, can be built in a short time?

The main distinctive features, including the layout of domed residential buildings, should be considered in detail. The foundation of a house is the base of any building. Its characteristics will be determined by the following factors: the type and mechanical properties of the soil.

When constructing such a structure, there will be an economical consumption of building materials: the building will be lightweight, saving on laying the foundation from 25 to 40%.

Extensions can be erected to the finished house, a maximum of 5 pieces, added to the first floor of the spherical structure. They do not lead to a loss of system rigidity and can be located in any of the 5 openings of the dome. They are used in the form of connecting adjacent domes, verandas, greenhouses, solariums, baths, etc. The positive point is a significant increase in the required area. At the final stage of construction, interior decoration and layout do not require load-bearing walls. Therefore, you can afford rooms, lofts, attics and other architectural delights without compromising the strength of the structure.

Dome houses are built from wooden beams filled with polystyrene foam or fiberglass panels. These modern, lightweight and reliable materials are usually used in the form of thermal insulation material. For climate conditions in the middle zone, the required thickness of the insulating material will be 15 cm, which can be installed without difficulty with normal wall thickness. Recently, expanding foam mass has been used for these purposes.

Bituminous shingles are traditionally used as roofing material for houses: they have a rather attractive appearance, and the price is also acceptable. This material is easy to work with and easy to choose the right texture and color.

The design of a domed building can take into account windows of various shapes: regular rectangular, five, six and triangular. They can be a decoration for an unusual facade. Proper placement of windows of any shape will make it possible to save on lighting and heating of the building. Even in winter, on sunny days, the house will be able to receive additional passive heating from sunlight.

Materials used for interior decoration of the house:

lining;
drywall;
plastic;
all kinds of decorative plasters.

Thanks to such a variety of finishing materials, the interior of the house will be combined and at the same time look impressive and beautiful.

Ventilation and heating systems for domed buildings are similar to those used in classical construction. For proper heating, you need to purchase and install heating devices, the power of which will be approximately 30% less.

Home benefits

Feedback from people who have already experienced what it is like to live in domed houses help determine the following positive aspects of the presented structures:

The ability to obtain maximum volume with a minimum surface area;
Ideal shape that can withstand large gusts of wind and snow loads;
Saving on foundation. The lightness of the structure reduces the load on the soil, which allows the use of a more economical type of foundation. Typically, a strip foundation is made for a prefabricated house to a depth of 90 cm. As a result, the customer is protected from problems with the building being skewed and cracks in the foundation.
Save energy in cold, warm or hot climates. In cold climates, an ordinary stone house consumes about 225 kWh/m2 per year for heating and hot water supply; wooden - 100 kWh/m2 per year. The wall of a domed frame house, with an average thickness of 200 mm, meets the requirements of modern standards and, moreover, exceeds them. Even in cold weather, the temperature decrease when indoor heating is turned off is 2° C per day. You can compare the cost of maintaining two buildings over 50 years - brick and frame. It turns out that with the difference (not in favor of a brick one) you can build another frame house.
Lack of seasonality of construction.
Low prices. A reliable domed wood-frame house costs less than a traditional stone one.
High stability.

Flaws

There are disadvantages to the construction of spherical buildings, although their prerequisites are absolutely not in the design, efficiency, or the method of construction itself. They are rather psychological and informational in nature. There is little awareness of dome construction, and a lack of specific knowledge in the field of Fullerian geometry.

Building a domed house with your own hands

You can build a sphere house with your own hands. When constructing such a structure, the following technology is used:

After laying the foundation, the components of the structure are delivered to the construction site. Even a person who does not have much knowledge in construction can assemble the frame. Purchased materials are supplied completely ready for assembly, they are marked and color coded.
In order to simplify the work of assembling the dome, it is preferable to find an assistant. To assemble the frame, boards and steel modules are used. The process is carried out using a wrench; assembly accessibility is achieved thanks to pre-prepared holes.
After assembly is completed, the frame is sheathed with waterproof plywood and insulated using steam and heat insulating materials. A typical thermal insulation layer will be 15 cm. To build a second floor, there will be no need to install auxiliary load-bearing walls.
The exterior of the building is protected by windows and a roof. For its construction, galvanization, tin, shingles, and flexible bitumen shingles are used. The construction ends with interior layout and finishing. To achieve a normal result, textured plasters, drywall, paints, lining and plywood panels are used.

A turnkey domed house can be erected in a short period of time. You can learn more about the design features, layout and their construction from the video.

Nowadays, few people can be surprised by a new residential building, but this rule does not apply to the popular spherical or domed houses, the designs and prices of which are so varied that they cannot leave any buyer indifferent. Spherical buildings are unique in themselves; their design looks unusual in any area. Moreover, the incredible appearance of the domed house is not its only advantage.

Due to its unique design, each house project can differ significantly from another, since it is possible to use radically different parts. Such construction projects are highly functional. Every day they become more and more popular in the Russian construction market.

What is a domed house: features and history

A domed house is usually understood as a construction project with a spherical, rounded roof. However, this is only a general description of this type of building. Many people note that the domed house looks like an Eskimo dwelling (like an igloo).

Modern spherical buildings look simply incredible, the designs are amazing. For designers, a special task is the competent combination of one main sphere with five side ones. The finished result of the project largely depends on the designer’s imagination and your personal preferences.

Source greenadaptability.wordpress.com

The first spherical buildings appeared in Byzantium, and the Eskimos began to create their homes in conditions of extremely low temperatures many years ago. From this we can draw a simple conclusion - in ancient times, round-shaped houses were no less popular than today, but then a more durable material was used for their construction - natural stone.

The northern peoples were the first to notice that spherical buildings have high wind resistance and earthquake resistance.

In 1951, American architect Richard Buckminster Fuller proposed using a spherical structure as a basis for the construction of residential buildings.

Basic technologies for constructing domed houses

Today, there are several construction technologies by which domed houses are built; designs and prices, accordingly, also “play” in one direction or another, depending on the construction method. They can be made of materials such as brick, monolith, foam concrete, polystyrene foam and even clay. Moreover, buildings made of brick, monolith and foam concrete are not much different from standard structures of residential buildings. Technologies for the construction of domed houses are classified into construction:

based on geodetic sphere;

based on a pneumatic frame;

based on permanent formwork.

One of the most common technologies for constructing a spherical house is the combined use of polystyrene foam and expanded polystyrene - while the construction of the building is carried out using the Japanese method. However, such houses require additional manipulations to ensure year-round living.

The most budget-friendly and closest to standard conditions is the technology for constructing domed houses, based on the frame method of construction. As experts note, for this kind of buildings you can use a frame made of almost any material (with sufficient strength and service life). To connect parts, connectors of various modifications and sizes are used.

What foundation is suitable for a domed house?

You have decided on a site for the construction of a construction project, have decided that it will be a dome house, have drawn up a layout plan with established dimensions, which means it’s time to move on to building the foundation.

Its construction requires preliminary preparation - it is necessary to mark the site, determine the zero mark and other parameters (for these purposes we recommend using a level - a geodetic device for determining the difference in heights). You should not neglect the help of professionals in the field of geodetic work.

The very essence of domed housing construction implies the absence of ceilings and load-bearing supports. This not only provides up to 30% savings on wall and ceiling materials: the structure becomes lightweight and does not require a massive foundation.

After all the preparatory work has been completed, you should proceed to digging a trench for a strip foundation (this is the best option for creating a domed house).

Source rmnt.ru

Also, a pile type of foundation is often used for a domed house.

Source: seattlehelpers.org

A strip foundation is a reinforced concrete structure installed around the perimeter of the entire construction site. As a rule, such an installation consists of lathing (reinforcing mesh) and hardened concrete mixture. To create the sheathing, reinforcement with a diameter of 12 mm with wire binding is suitable. Next, the cement-sand mortar is poured.

When choosing the depth of the trench, keep in mind that the foundation should be located in a place where the soil freezes (this is 1500 mm below the zero level).

When constructing a pile foundation for the construction of a domed house, as a rule, screw, driven or concrete piles are used, depending on the quality of the soil.

Frame technology for a domed house

During construction, round house projects most often involve the use of frame technology - it ensures ease of construction. The frame is assembled from special metal pipes or timber, after which the resulting structure is sheathed with sheet building material (OSB board or plywood). An insulating element (mineral wool, jute, expanded polystyrene) is placed in the layers between the sheets.

Monolithic reinforced concrete can also be used to construct the frame of a domed house. However, this method is used very rarely in our country, due to the lower price of lumber. And don’t forget about the need for good thermal insulation of the dome, which wood copes with much better than concrete.

Today, there are two options for the frame scheme of domed houses: creating a stratodesic or geodesic dome. Each of them has both advantages and disadvantages. In the process of creating a construction project, a more suitable frame model is selected.

For exterior finishing, pressed cellulose impregnated with bitumen is used, but other materials can be used, as long as they are waterproof. The inside of the frame is covered with boards, and mineral wool is used as insulation. During construction, some triangles are left open, after which similar-shaped frames with double-glazed windows are installed in them.

Technology for constructing a domed house based on a pneumatic frame

The method of constructing a spherical house based on a pneumatic frame is distinguished by an unusual and rather complex technology, and requires the use of special machinery and equipment, due to which the time for building a house is reduced to a minimum.

The foundation for such a house is made of strip or slab. The frame is a dome made of metal rods connected to each other by welding.

This technology must involve a prefabricated pneumatic frame. It is made individually and, when inflated, completely follows the contours of the inner surface of the dome. In those places where windows and doors should be, the frame has protrusions of a given shape and size. Manufacturing a pneumatic frame is the most expensive and complex stage of construction, but since the technology cuts construction costs in half, its price is fully recouped.

Source gr.pinterest.com

The pneumatic frame is inflated from the inside of the metal sheathing, after which a cement-polymer mortar, shotcrete or polystyrene foam is sprayed on the outside using special equipment. The main material of the dome is applied in layers, with breaks for each layer to harden. I do the same on the inside of the dome, and after the walls have completely hardened, they begin finishing.

Features of the planning and interior design of a spherical residential building

The layout of a domed house has a number of differences from the rectangular structure we are used to. However, this does not at all limit home owners in choosing the design of the room. On the contrary, the unusual appearance of the room allows you to implement the most extraordinary interior solutions.

Source argo-project.ru

It is better to make some decorative elements and furniture to order, since most products are designed to be placed against standard walls. An excellent solution would be semicircular paintings and upholstered frameless furniture.

For a living room or office, wooden furniture will be suitable, which will exactly follow the curves of the walls, which will give the room an even more unusual ambience.

When installing communication systems, you should take into account the shape of the internal walls, as well as the technical and operational properties of the finishing materials used.

A fireplace is an integral attribute of the living room. In spherical houses, it is best to place the fireplace in the center of the room - if you want to retain all the incoming heat and solve the problem of the lack of a flat wall for mounting this interior element.

Advantages and disadvantages of domed houses

In addition to the unique external characteristics, the dome house has a number of undeniable advantages:

affordable price;

no massive concrete platform required;

savings on assembly speed;

minimum construction waste;

not a lot of building materials are required for a dome house;

The outer surface area of domed buildings is smaller, and the internal volume of space is larger (corners are cut), thereby reducing heat loss in winter and heat absorption in summer;

Experts include the following disadvantages of domed houses:

there are very few professional companies on the Russian market, the topic is quite new, enthusiastic dome builders are just trying to conquer our country;

experience in calculations and absolute accuracy in the manufacture of parts is required;

suppliers of high-quality raw materials are “worth their weight in gold”; good lumber is difficult to find;

the period of useful use of the house is inferior to stone and block buildings;

non-standard windows, made to special order, certain difficulties during installation.

But these disadvantages quickly disappear if you do not try to build a house yourself, but immediately turn to a construction company that has proven itself well in the construction market. This way you will save a lot of time and effort, and in the end you will get a high-quality domed house in which you will live cozy and comfortable. And the specialists will definitely take into account all your wishes regarding the layout.

Conclusion

Considering domed houses as permanent housing, the projects and prices for them can be sorted out endlessly, because, despite the fact that such buildings appeared on the construction market relatively recently, there is no limit to the variety of projects. You can choose the simplest domed house for yourself; projects of such buildings are inexpensive, or create a special one, according to your own wishes and preferences. For example, you can take Dobrosfera domed houses, projects and prices; photos of each of them can be viewed in more detail on the website. And professional architects and designers will be happy to help you with this.

Domed houses of unusual shape are a bold idea. The original form stands out from the identical faceless mass of buildings of the same type, attracts attention, and fits perfectly into the surrounding landscape.

The technology for constructing domed houses has been developed in the seventies of the last century. The idea of a private house of an unusual shape, with large internal space and an open layout quickly spread across different countries.

The original appearance is emphasized by a wide variety of materials for exterior and interior decoration:

glass and wood;
metal, decorative stone, fiberglass;
and brick.

Dome houses consist from frame, insulation and cladding. In private individual construction, the frame is made of wood. An alternative to a frame house - monolithic concrete dome. Using Japanese technology, houses are even built from wood and then painted.

There is also a mystical component. Drawing parallels with temples and churches, esotericists claim that the domed vault of the building, which has no corners, attracts positive energy. Pure natural energy heals residents, gives peace, tranquility, and harmonizes relationships.

According to the design features of the frame, they are distinguished:

Geodesic dome;
Stratodesic dome;
Monolithic concrete dome.

Geodesic dome

The principle of constructing a dome-type frame was developed by the American architect Richard Fuller based on the geometric shape of the Earth.

A geodesic dome is an architectural structure in the shape of a sphere, formed by connecting beams into triangles according to the honeycomb principle. System of interconnected rods has a high load-bearing capacity regardless of the strength characteristics of the material.

The greater the height of the dome, the more elements are used, triangles and polygons are formed. By increasing the number of geometric shapes in the dome, the load-bearing capacity of the structure increases.

At the same time, little materials are required for construction, and the specific weight of the structure is small. The triangles are connected to each other by a specially shaped fastening element, a connector.

Important! The geodetic frame should only be assembled using connectors.

Connecting elements, regardless of the material of the beams, always metal or plastic. To protect against corrosion, metal connectors are painted.

Fuller's spherical dome found application in buildings where it is necessary to obtain the maximum volume of a room with minimal weight. Stadiums, industrial buildings, scientific laboratories, warehouses, exhibition centers are built on the basis of a honeycomb geodesic dome.

Stratodesic

The stratodesic dome has axial symmetry, formed by bent arc pillars converging at one point. Horizontal jumpers encircle the frame in a circle. Segments of a stratodesic dome are shaped like trapezoids rather than triangles.

In the first rows from the foundation the cells are large. Approaching the dome, the size of the segments decreases.

The main difference between the design and the geodesic dome is that twisting deformation is compensated not by the frame, but by the skin.

After the construction of the lower row of lintels, the structure is immediately sheathed with wall material. Without cladding, the frame will collapse.

The connection of the beams of the stratodesic dome occurs without connectors, due to inserting beams into each other using locks. The joints are additionally secured with bolts and dowels.

note

Connectorless connection technology is suitable only for wooden stratodesic frame. The joints bear the heaviest load; incorrect execution will lead to divergence of joints, loss of rigidity and collapse of the structure.

The joints of curved wooden posts at the convergence point of the strata frame are made using cuts of various shapes.

The stratodesic shape of the frame forms large trapezoidal cells, which allows the use of window and door structures of a standard type.

After assembling the frame, sheathing is performed on both sides with intermediate insulation. Then window and door blocks and partitions are installed. Start finishing.

Monolithic concrete

A monolithic dome does not belong to frame construction technology. Capital buildings. They are built using two methods:

Shotcrete, layer-by-layer spraying under pressure.
Pouring concrete mixture into permanent formwork made of foamed polystyrene.

Shotcrete

When choosing the shotcrete construction method, after erecting the foundation, pneumatic frame made of fabric is inflated with waterproof impregnation. Metal reinforcing mesh is pneumatically laid and bent to allow window and door openings to pass through.

concrete mixture, shotcrete, is applied under pressure several times until the planned wall thickness is achieved. After the concrete reaches working strength, the fabric sphere is blown away, the mortar deposits are cleaned off, and insulation, window installation, installation of engineering equipment, and finishing begin.

Permanent formwork

Expanded polystyrene frame produced in the factory, is delivered to the construction site as a set of blocks ready for installation. The formwork blocks are connected to each other, the joints are sealed with polyurethane foam.

Reinforcement is installed into the formwork and concrete is poured. Once cured, window and door fillers are installed and finishing begins.

Advantages and disadvantages

Any house - combination of positive and negative points. No technology is perfect; there are always disadvantages and advantages, sometimes resulting from each other. A minus in one capacity turns into a plus in another. The balance of bad and good produces amazing results.

Pros of domed buildings

In addition to the obvious aesthetic qualities, the sphere has excellent operational properties for construction:

no corners reduces wind load. Air flows simply flow around the structure, precipitation rolls off the surface;
high seismic resistance thanks to the form. If up to 35% of the elements are completely destroyed, the structure will not collapse. No shape other than spherical gives such indicators;
The dome enhances natural light. Rectangular structures absorb light;
the same temperature throughout the room and free air circulation makes it unique microclimate;
high energy efficiency due to the smaller heat transfer surface area;
material savings compared to a rectangular house of the same area will be 20-25%.

The frame and other materials are delivered to the site in separate parts, ready for installation.

The light weight of the structure saves foundation costs. The most common structural designs for foundations for dome-shaped houses are: pile, strip, slab.

Minuses

In addition to complex calculations (in three dimensions), the disadvantages of spherical buildings also include:

small selection of finishing materials. Not all finishing materials are capable of repeating a curved surface. Due to the decreasing surface of the walls towards the ceiling, it is difficult to wallpaper rooms. In bathrooms and bathrooms, difficulties arise with the use of ceramic tiles;
rooms located in a circle will have irregular shape, expanding from the entrance;
natural lighting of the central room in a one-story house only possible through the roof. It is extremely difficult to provide a natural light source in a two-story building;
lack of materials for roofing. Soft tiles and rolled materials that perfectly match the dome shape limit the choice. Often the roof is made of the same materials as the walls of the building;
for now there is no unified regulatory framework rules for the construction of domed houses in Russia;
design diagram basements are not provided, ground floors.

Projects and features of the layout of dome-type houses

Unusual, creative, non-standard - these are the first thoughts that arise in a person’s head when they see a domed house. Nevertheless, absolutely all buildings are subject to architectural rules.

Entry group

The entrance group is an important architectural element of a private house. The front door invites guests and residents to enter, attracts attention, and decorates the facade.

In a spherical house Installing a front door is not easy. Removing connections under the opening does not affect the rigidity of the geodesic frame; in a stratodesic dome, the openings must be strengthened. The main problem is fitting a rectangular shape into a curved surface.

There are three input group solutions:

installation of a vestibule at the entrance to the house;
removal of frame segments with a margin. After installing the door jamb, the voids are filled with shortened ribs, rigidly fixing the front door;
ordering the production of an individual door that follows the shape of the wall.

The canopy above the door not only protects from rain and sun, but also frames the door. Columns supporting the canopy will give the entrance group a thoughtful, finished look.

Organization of space

The layout of a spherical house will differ from the usual one, but will allow you to realize the most non-standard design fantasies.

All partitions are made of lightweight materials: sheets, wood panels on metal profiles or wooden beams.

In the floor layout, the central place is occupied by a common passage room, the remaining rooms are arranged segmentally in a circle.

In the center there are:

living rooms, kitchens, dining rooms;
passage room without purpose;
corridor.

The common area will be connected by doors to the other rooms.

If the house has more than one floor, a spiral staircase looks good in the center, emphasizing the round shape of the building. The second floor traditionally houses bedrooms, individual rooms, offices, and libraries. By installing even a small section of glazing in the center of the dome, get a light source during the day and a real starry sky at night.

If there is not enough space, two or three domes are connected by transitions. For summer relaxation, open terraces are built in a circle. A glazed veranda will increase the area of the house.

The entrance door is separated vestibule to prevent heat loss in winter and maintain microclimate in summer.

Opinions about the complexity of furnishing a domed house are incorrect. In each room, only one wall is curved, with one or more windows. On this wall you can easily place:

shelves for books and interior trinkets;
built-in wardrobes;
paintings;
lamps;
drapery.

Let this wall be just decoration.

If the layout cannot do without using part of the wall, for example, for a desk or head of a bed, the desired section of the wall is brought to a plane using sheets of plasterboard or.

Interior decoration

The inside of domed houses is finished with:

wooden clapboard. The lining is attached vertically, horizontally, with patterns. Wood gives the space an ecological style and subtle aroma;
wallpaper. The strips narrow towards the ceiling and are separated by bent wooden slats;
smooth and structured plasters and paints. A palette of textures and colors will add variety to the color scheme of the premises.

A good solution would be to place fireplace in the center of the living room. The symbol of the family hearth creates warmth, comfort, and warms the family on long winter evenings.

Glazing

The important quality of the geodesic frame to keep its shape is used to increase the glazing area.

Glass will make the facade of the house light and airy, will provide natural light at any time of the year. A glass dome will turn the second floor into an observation deck. If window units are at a height, they are equipped with automatic opening systems.

With the right approach, a domed house will never disappoint residents, remaining for many years an unusual, beautiful home with excellent performance qualities.

Photos of finished houses inside and outside

There are various technologies that allow you to build any type of housing. The designs of such buildings differ significantly. It all depends on what form is chosen for this and what materials are used in construction. We can say with confidence that the house-sphere is quite common today. This is an extraordinary architectural design that has regained popularity.

Ready-made spherical house project

A sphere house is a building that has a rounded shape of both the walls and the roof structure. It is endowed with certain technical characteristics that have long been appreciated by construction specialists around the world.

Some buildings of this type have survived to this day. These are architectural monuments of past centuries. Sphere houses are also called domed houses.

Technologies for the construction of domed houses

There are several ways to build a domed house with your own hands. Materials from which they can be constructed:

brick;
foam concrete;
monolith;
expanded polystyrene;
Styrofoam;
clay.

Spherical houses, built of brick, foam concrete or monolithic, have almost the same characteristics as the standard construction of any home. But other materials may not always be used.

Original project of a domed house

More interesting is the construction of a domed house made of polystyrene foam and polystyrene foam using Japanese technology. Such houses have certain characteristics, and in some cases specialists improve them a little so that they can be lived in year-round.

Another technology for constructing domed houses is frame construction.
The frame can be made of any material, and all its elements are connected by special connectors of different sizes and types.

Advantages of a domed house

Spherical houses, which are built using any chosen technology, are endowed with similar properties and characteristics.

There are several advantages of such houses.

Moreover, houses can be installed in any climatic conditions. Dome roofs can easily withstand snow loads. They do not leak, since precipitation does not linger on the roof structure.

The cost of constructing such a structure is low. The basis of the structure is often a frame, which is lined with various modern materials. It can be:

OSB sheets;
plywood;
Styrofoam;
drywall;
other similar sheet materials.

Finishing the frame of a domed house with sheet materials

Thanks to modern means used in the construction of domed houses, the buildings are endowed with a high level of energy efficiency. .

During the construction process, do not forget about the ventilation system, which is necessary for any building.

Such a house is considered an excellent sound insulator. Especially if it is built from polystyrene foam, these are Japanese housing construction technologies.

The technology for constructing spherical cottages can be any. The designs of the future structure and its appearance play a big role. So, domed houses can be full-fledged or not.

That is, in the first case, only the roof structure is constructed in the form of a dome, and in the second, the entire house is constructed. Building all this yourself will not be difficult.

Project option for a two-story domed house

Most importantly, it is necessary to correctly draw up design drawings and calculate all building materials.
According to the type of roofing structure, spherical houses can be in the shape of an icosahedron or based on simple polyhedra.

The first type is considered today to be a rational option, which allows you to correctly divide space into certain vectors.

And this only adds strength to the structure, since connectors will connect all the elements.

The technology for constructing a dome-shaped roof is quite complex. It includes calculating the required number of wooden beams, boards and other structural elements that must be installed on a solid foundation. Often this is a frame.

If the structure is complete and is a spherical house, then the shape of the dome itself can be:

The first type of structure is based on a round frame. The structure itself has the shape of a ball. The second type is characterized by the fact that it is assembled on a specific structure, the height of which can be any. The oval shape of the spherical house is more interesting than all the others.

The base can be round or oval. Semicircular buildings are structures that have walls 1-1.5 meters high on the foundation, and only after that a dome is built. Polygonal houses are considered unusual. They are based on polygonal structures and also have the shape of a ball, only with an imperfectly flat surface.

The layout of each type of building is different. It all depends on what functionality is initially put into the home.

Special devices for the construction of a domed house

Firstly, in order to build spherical houses, it is necessary to initially determine what shape and type they can be. Secondly, you need to make the correct calculation of materials and means for their construction. Next, a construction technology is selected, which can be with or without a frame.
So, the construction of a domed house is possible only with the use of:

connectors;
metal corners;
various special fastenings and so on.

A connector is an element that serves to connect the wood frame of both the roof structure and the entire building.

It can be five- or six-rayed. It is worth noting that the usable area of cottages built using frame technology is quite large. Thanks to this, a unique interior of the home is created.

An example of interior design for a spherical house

Metal corners are used for the construction of small dome-shaped cottages. They are practical and can also be mounted on a wooden frame. There are also plastic fasteners that are used to erect foam dome houses. This construction technology is considered the simplest and fastest to implement.

You can buy all the elements for a better connection of the house frame at any specialized store. Although some modern craftsmen make them themselves.
The price of metal corners and connectors will be more expensive than similar devices made of thick plastic.

Detailed layout of the sphere house

Spherical, domed dwellings have been known for a long time - yarangas, tents, wigwams, etc. - built on this principle. They are distinguished by their high stability and ease of construction, which is what earned them the popularity of our ancestors. But domed houses in their pure form, as a phenomenon of modern construction, appeared not so long ago - approximately in the second half of the last century. When the American scientist Fuller decomposed the dome structure into simple figures - triangles, from which the entire structure is often assembled. It is on this principle that many spherical houses are built today.

Domed houses: technologies and their features

Dome or spherical house are the names of one construction technology. Actually, the name reflects the peculiarity of this type of housing construction - the house is not rectangular, but is made in the form of a hemisphere. More precisely, in the form of a polyhedron, approaching a sphere in appearance.

This shape better withstands wind and snow loads, with an equal building area to a rectangular one, and has more usable area. But in such a house there is unlikely to be at least one rectangular or square room. At least one side will be uneven. This complicates the planning, finishing, selection and installation of furniture. Most likely, all or most of the furnishings will have to be made “to order”, according to your own dimensions and sketches.

Dome houses are built mainly using frame technology, so the construction is lightweight. The frame is assembled from timber or metal pipes, sheathed with sheet building material (plywood, OSB). Insulation (expanded polystyrene, mineral wool, foam glass, environmental materials such as jute, dried seaweed, etc.) is laid between the frame posts. That is, apart from the unusual shape, there is no news; the materials are selected as for an ordinary frame house.

There are domed houses made of monolithic reinforced concrete. But this technology is used infrequently, especially in our country, where lumber is sometimes cheaper. If we also take into account the need for good thermal insulation of a concrete dome, its unpopularity becomes clear.

With the frames of domed houses, not everything is so simple. There are two technologies by which they are assembled: geodesic and stratodesic domes. They have their own characteristics that can influence your choice.
