Dome houses (spherical): geodesic dome. Domed houses: examples and review of construction technologies How to assemble a domed house

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 own plot, raise children in environmentally friendly and natural conditions for a person. 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 in modern construction market around 2008, they cannot in any way be attributed to the 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 people to live in, solves the problem of creating a convenient structure that allows preventing the influence of adverse factors caused by environment. 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 endure vibrations earth's crust force up to 10-12 points.

Even experienced builders I am often interested in the question of how to make calculations domed house and what is its cost. 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. The foundation of a house is the base of any building. Its characteristics will be determined by the following factors: type and mechanical properties 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%.

TO ready home you can build extensions, 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. Positive point - significant increase 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 expanded polystyrene or fiberglass panels. These modern, lightweight and reliable materials are usually used in the form thermal insulation material. For climate conditions middle zone, required thickness insulation 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.

As roofing material traditionally used for home bitumen shingles: it has a rather attractive appearance, 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 diversity 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

Reviews from people who have already experienced what it is like to live in domed houses help determine the following: positive sides presented designs:

  • 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 ground, which allows the use of more economical type 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.
  • Energy savings in both cold and 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. Dome wall frame house with an average thickness of 200 mm, it 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 the brick one) you can build another frame house.
  • Lack of seasonality of construction.
  • Low prices. Reliable dome timber frame house costs less than traditional stone.
  • 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:

  1. 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.
  2. 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 wrench, accessibility of assembly is achieved thanks to pre-prepared holes.
  3. 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 the second floor, install auxiliary load-bearing walls not required.
  4. The exterior of the building is protected by windows and a roof. For its construction, galvanization, tin, shingles, and flexible bitumen shingles are used. Construction is finishing internal layout and finishing. To achieve a normal result, use textured plasters, drywall, paints, lining and plywood panels.

A turnkey dome 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.

Step-by-step instructions for making a mobile geodome with your own hands

DIY geodesic dome

Good afternoon This article will be useful for anyone who is interested in a geodome and who wants to create this amazing structure with their own hands. In this article we will not go into the general theory of geodomes, because This is a comprehensive topic, described in other articles. Below are specific instructions on how to make a small mobile geodome. Such a dome will be ideal solution for all travelers and lovers of living outdoors, suitable for summerhouse or children's house. This dome is a universal mobile tent, compact for transportation (suitable for any passenger car), quick to assemble (2-3 hours), very durable and resistant to natural elements. This house is also round and harmonious. People say that, thanks to its synergetic (geodesic) frame structure, the geodome has a beneficial effect on the surrounding space and harmonizes it. We have been convinced of this many times through experience. Having installed a stove in such a house, you can safely live in it until late autumn. There are options for wintering, but they require insulation.

Many photo materials for this article were collected from various sources, for which many thanks to their creators. Also, special thanks to our Latvian friends who inspired us to create such instructions.

So, let's begin!

This is the kind of geodesic dome you should end up with.

Dome diameter: 6.2 meters
Dome height: 3.65 meters
Number of parts: 165
Number of standard sizes: 3
Area: 30 sq.m.
Number of bolts: 61
Bolt size: M8x60

Selection of frame material

Convenient and inexpensive material for the frame of a geodesic dome - steel pipe(electric welded). Suitable for our dome round pipe 25x1.5mm. You can buy such a pipe at the nearest market or metal warehouse. Typically, pipes are sold six meters long. For ease of delivery, you can cut them into 3 or 1.5 meters.

So we need 252 meters of pipe (42 pipes of 6 meters each). The cost is about 6,000 rubles.

Selecting tools and creating a workspace

To make a frame you will need the following set of tools:

Manual grinder with metal discs (or cutting machine)
Hand drill (or drill press)
Metal drills (diameter 9mm)
Hand press
Vise
Desk (minimum 1.5 meters long)

Pipe cutting



Selecting a hand press and preparing the workplace

You can look at some models of hand press. If you have a friendly metalworking industry, you are lucky).

For fast and accurate manufacturing, you will need various equipment and devices that help and speed up the process. Here you can show your divine intellect or use already thought-up ideas.

Next stages of production

Flattening the ends of the pipe (in the same plane!!!)
Drilling
Bend the ends 11 degrees relative to the entire pipe (this is necessary to “round” the frame into a dome)

Tip diagram:


The first end of the pipe is flattened arbitrarily, but the second end must be flattened in the same plane as the first end. Therefore, craftsmen use a simple “slit” device, clamping the first flattened tip in a certain plane. The second end is flattened in the same plane. After flattening, it is recommended to process the ends with a file or beam (remove sharp corners and burrs).

To drill holes, you can make a small device, shown in the photo below. IN in this case The device helps secure the pipe. During this operation, the exact distance between the centers of the holes is also checked (with a tape measure or a mark on the table).

Having drilled all the holes, you need to bend the flat ends of the pipe 11 degrees relative to the pipe. To do this, you can use the device below. In this case, a line corresponding to 11 degrees is drawn on the table, which is the mark to which you make the bend.








After all the operations you should get something like this:


Painting elements

There are many tips on this issue that you can find on the Internet. After painting, it is recommended to color-code all elements for ease of assembly.

Fasteners

M8 bolt, 50mm long - 65 pieces
M8 washer - 130 pieces
Nut M8 - 65 pieces

Assembly


You will need 2-3 people, M8 wrenches (or a wrench) and a small stepladder (or tortoise). The first time it will be more convenient to assemble from the bottom up. Use a color scheme for assembly. Assemble the dome in an orderly manner, in a spiral!!! Those. lay out and fasten the bottom ring first, then attach the next row to it, connect the row. Continue in this manner, assembling each row in order.

To keep the post from being too long, instructions for making the dome shell will follow in the next post.

We wish you successful creativity!!!

Construction of a dome house with your own hands + Video. Recently, specific housing has been gaining popularity. People are looking for new solutions to make them garden areas and the courtyards had at least some of that zest, surprising and inspiring them and passers-by. Few people are interested in banal houses made according to standard templates. The desire to stand out from the rest and build on a summer cottage unusual house forces people to turn to professional agencies, and it is not at all uncommon when it is necessary to turn to professional builders and designers.

Such houses are often made in the shape of a hemisphere, and they are filled with originality, grace, and beauty. But you can live in such a house, and you don’t even have to use the help of builders and designers. Build domed house with your own hands is quite possible.

Specifics

For many it will be a revelation that spherical design Can withstand heavy snow loads and withstand gusty winds. For regions with harsh climatic conditions, this perfect option. Such structures are stable and powerful, and what is noteworthy is that they have no load-bearing structures. Due to the symmetry of the forms, the appearance of the dome visually seems smaller, but on the contrary, the space inside is larger. Getting the right amount of usable space, given that the house actually takes up little space, is the hallmark of such custom buildings.

Such houses weigh little, since usually few materials are used during construction. Due to this, you can save money when creating the base. The construction technology has some tricks, but it is not difficult to master.

Advantages

A beautiful round house has a huge number of advantages, which lie not so much in its uniqueness and appearance, but in the following useful properties:


Due to energy efficiency, you can build a domed house in any region. Such buildings are also not afraid of hurricanes, heavy snowfalls and other natural phenomena, since they are many times more stable than rectangular ones.

Required materials

Before starting construction, you should prepare all the equipment and materials so that when work begins, you do not delay construction by searching for this or that item.

So, you will need:


You can choose a dome-type housing project from the options offered here, or order it from an agency. There must be drawings, since without them it will not be possible to make a spherical structure.

Work process

Preparation

To prepare, you will need to do the following:

And finally, we move on to the most interesting point - how to build a domed house.

Construction instructions

The construction includes the following stages:


Before fastening, make sure that everything lies strictly horizontally using building level. Each element must be connected to each other using screws, and to using anchor bolts with a length of 40 cm. To save money, you can use reinforcement with a diameter of 2 cm, and this will work out even better.


You can connect the edges of a house without the help of connectors if you assemble a dome from triangles, the boards of which are 100% matched. In this case, the dome panels will be connected with screws. When assembling the frame, leave an opening for doors and windows.

  • Exterior finishing. For finishing the outside of a hemisphere, it will be easiest to use roofing felt. You will need to cut out neat triangles from it that will coincide with the inside of the panels that were used for the frame. Such elements should be fixed using special glue or resin melted on the dome.

The interior decoration of the house will be done to your taste. Ergonomic houses dome type look great inside and out, and with good imagination you can create an amazing layout. And most importantly, the construction of such a building is a significant saving on materials and work.

A greenhouse at the dacha has long become not only a help in growing vegetables, but also an opportunity to realize one’s creative ambitions. Among all the innovative solutions special attention deserves the geodesic dome - the brainchild of modern architecture. Interest in original design The explanation is simple - even an inexperienced craftsman can install such a greenhouse on his site - the hemisphere is easily assembled from simple parts, and the productivity of its beds is not inferior to the yields from standard structures.

Geodesic dome - beautiful, practical and simple

The growing popularity of domed greenhouses is explained by several factors:

  1. Installation does not require a solid foundation, since its design is much lighter than conventional shelters of similar size.
  2. The structure is easy to assemble and disassemble, and if necessary, it is easy to move it to a new location.
  3. The hemispherical shape is highly durable and stable. The honeycomb frame resists better strong winds, easily withstands snowfalls and has good earthquake resistance.
  4. Compared to traditional forms of shelters, the construction of a dome greenhouse is cheaper, since complex equipment is not required for installation. Simple available materials are used in construction - wooden blocks or plastic tubes for the frame, screws, polycarbonate, agrofibre or greenhouse film for cladding.
  5. Due to the unique sectional structure, there is no need to install internal supports, and this significantly saves building materials.
  6. Unlike rectangular greenhouses in a hemisphere, there is no need to orient the beds relative to the cardinal points - the plants are always well lit.

In the geodome it is easy to provide the necessary microclimate for growing several crops of garden crops per year. The soil always warms up well, and environmentally friendly materials are used to maintain temperature stability. thermal accumulators– water tanks.

In winter, the geodome can withstand even heavy snowfall

How to build a dome greenhouse yourself

It is not difficult to build such a structure on your site. To do this, you will need to calculate the dimensions of the sections, print out the assembly diagram, prepare the frame parts, clear the space for installing the greenhouse, and you can begin installation.

Options for dome greenhouses

Principles of designing a dome frame

At their core, all geodesic domes are polyhedra, the faces of which form a surface that is as close in shape as possible to a sphere. The shape of the edges may be different, but the triangle is considered the most stable and stable. Therefore, in most cases the main structural element to create a hemispherical frame is a triangle.

Triangular sections - the basis of a streamlined and stable frame

For the construction of the frame of small domed buildings on summer cottages– greenhouses, gazebos, guest houses – frame-panel technology based on isosceles triangles is most often used different sizes. The smaller the size of the sections, the more of them will be needed to create a spherical greenhouse. The principle of connecting them together is similar to sewing a soccer ball - the triangles are connected into convex hexagons and pentagons, which are combined into a stable hemisphere.

Advice! If the connection angles of the fragments were not taken into account when calculating the geodome, then installation is best done using connectors with 4, 5 and 6 blades.

Formula for calculating the length of the dome elements

In order not to make mistakes during the assembly process, you need to calculate in advance the length of all the ribs, the correct sequence of their alternation, and the angles at which the elements are connected. To draw up an optimal scheme, it is necessary to use special formulas. The calculation of a geodesic dome is based on specific dimensions:

  • radius of the base of the structure;
  • height of the greenhouse (expressed as a fraction of the diameter of the sphere, H);
  • sectioning frequency (V).

Wooden blocks for installation

The higher the numeric index V (1, 2, 3...), the more types of edges will need to be prepared. Dome 1V is a truncated icosahedron, all edges are the same length. This structure is more like a pyramid with five sides. For construction home greenhouse The best domes are 2V (two types of ribs, H = radius) and 3V (ribs A, B, C, height of the structure H = 5/8, 7/12, 5/12 diameter).

The length of each type of ribs (La, Lв, Lс...) is calculated using the formula L=R*K, where R is the radius of the base of the frame, and K is the coefficient for the frequency of breakdown.

Odds table

To calculate the required amount of material for cladding, use the formula for calculating the area of ​​a sphere: S=2π *R*H, where R is the radius of the base, and H is the calculated height of the greenhouse. For example, with a radius of the base of a 3V greenhouse of 4 m and a height of 3/8d, the calculation of the area will be as follows:

S=2*3.14*4*(3/8*8) = 75.36 m2

Preparing for frame installation

When building a geodesic dome with your own hands, you need to choose a light and durable material for the frame - wooden blocks, light metal rods or plastic pipes. It is better to impregnate wooden blocks with an antifungal compound before painting. When preparing fragments, it is extremely important to maintain accurate markings - all parts of the same type must be interchangeable.

Advice! Paint ribs of the same length with the same color. For example: ribs A are red, B are blue, C are yellow. To make it easier to work with the color assembly diagram, the markings of the finished ribs should match the markings on the drawing.

The number of fins by type and connectors for mounting each type of dome is calculated according to the diagrams.

Field work and foundation installation

To install a geodesic dome in your country house, you must select an open, unshaded area. Fertile soil It can be temporarily removed from the site, and the surface itself can be covered with clay and carefully leveled and compacted. If the soil is unstable, then you will have to pour a small foundation under the base or drive support piles under each corner of the base (the shape of the figure follows the outline of the bottom row of the diagram - a ten-, eight- or dodecagon).

The height of the base depends on how the building is intended to be used - for light summer a greenhouse is enough for 15-20 cm, and for winter greenhouse With warm beds it is better to raise the walls by 50-70 cm. The base is usually made of thick timber or wooden panels. A low temporary structure can be installed directly on bricks or stones laid at the corners of the bottom row of the frame.

Installation of the dome greenhouse base

Assembly and covering of the frame

It is better to assemble the structure from the bottom up, connecting the ribs with connectors or screws in accordance with the diagram. It is more convenient to assemble the top of the dome on the ground, and only then attach it to the frame. It is better to install such a “construction set for adults” with an assistant - it is more convenient to fix the parts. To enter during assembly, a door frame is inserted instead of several dome elements.

Advice! For ventilation, install 2 window frames in the upper part of the dome, made according to internal dimensions triangular element.

The next stage is covering the frame. For these works, a dense transparent material– greenhouse film, polycarbonate or glass. There are several ways to cover a domed greenhouse:

  • the finished frame is covered with film on top;
  • triangles are cut out of polycarbonate (according to the size of each frame cell) and attached like a mosaic;
  • Glass is inserted into the cells of the frame.

After the dome is completely sheathed, you need to check its tightness. If necessary, the joints of the slats and sheathing are additionally sealed.

Greenhouse project with beds

Internal arrangement of a geogreenhouse

The assembly of the geodome with your own hands is completed, it’s time to arrange it inside. Before laying the beds, it is necessary to prepare heating, watering and ventilation systems. Inside the dome on the north side it is necessary to fix a shiny material (foil, metallized film) - this way the plants and water tanks will receive more light and heat.

The temperature in the greenhouse is maintained using homemade heat accumulators - several barrels of water are installed under a reflective shield. The water will heat up during the day, thanks to which it will be maintained inside at night. required temperature. The same water can be used for drip irrigation.

Approximate diagram internal device geodesic greenhouse

To heat the beds under a layer of soil, you can lay corrugated pipes, into which warm air will be supplied.

The pipes are covered with a layer of manure or compost. Warm air circulates through the system under the beds thanks to a fan connected to solar battery. Additionally, to accumulate heat, several five-liter flasks, also filled with water, can be installed in the center of the greenhouse. In addition to built-in windows, you can install automatic system ventilation for scheduled ventilation.

The beds in the domed greenhouse are located around the perimeter.

It is better to make the width of the bed no more than 1.5 m, otherwise it will be difficult to care for the plants. Which garden bed to arrange is a matter of taste. You can build standard ones - up to 40 cm in height, tall or warm, vertical or two-tiered. If the radius of the base is large, a flower bed is usually set up in the center, on which tall or climbing crops are planted.

The beds in two tiers are well lit under a transparent arch

Naturally heated geodesic greenhouses are suitable for growing any crops from early spring to November. With a sufficiently large dome volume and the presence of additional heating and lighting, such greenhouses are suitable for year-round use even in areas with a temperate climate.

As you can see, it’s not difficult to build an original domed greenhouse on your own site. And if we take into account that the costs of its creation and maintenance are somewhat less than for other shelters, then we can safely say that the popularity of such structures will grow every year.

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 pure form, as a phenomenon 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- these 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, and with an equal building area to a rectangular one, it 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 metal building material(plywood, OSB). Insulation (expanded polystyrene, mineral wool, foam glass, environmental materials such as jute, dried seaweed, etc.). That is, except unusual shape, no news, materials are selected as for an ordinary frame house.

There are domed houses and 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.

Geodesic dome

The dome is divided into triangles, from which the polyhedron is assembled. The peculiarity of this technology is that it converges at one point a large number of beams To ensure their reliable fixation, connectors are used - special steel devices that allow you to reliably connect the elements of the supporting structure. Each connector costs from 600 to 1500 rubles ($10-25).

A geodesic dome for a spherical house is built on the basis of triangles

Given that the number of connectors amounts to tens or even hundreds, their availability greatly affects the cost of construction. Those who plan to build a domed house with their own hands try to do without connectors or make them themselves. The reasons are clear, but if the connection strength is insufficient, the building may collapse under load. So you have to be very, very careful when saving on this unit.

By the way, when using wooden beams there is a connectorless technology, but the assembly of such units requires high level carpentry and precision workmanship. And one more thing: they are not as reliable as connections with metal connectors.

The advantage of this type of frame is its stable design. If 35% of the elements are destroyed, the dome does not collapse. This has been tested in seismically active regions, during hurricanes. This stability allows you to easily remove a certain number of jumpers. That is, the opening for doors and windows can be made anywhere, of almost any size. The only thing that needs to be taken into account is that the windows will be triangular. There is no escape from this in this design. For many this is a critical flaw.

Another feature is that when assembling the frame, without cladding, it has good resistance to torsional loads, but does not take horizontal loads very well. Therefore, the frame is first assembled completely and only then it is sheathed.

Stratodesic dome

Dome houses of this design are assembled from trapezoidal sections. That is, its fragments are more like rectangles or squares. This structure allows the use of doors and windows of a standard design. For many this is a big plus.

The disadvantage of the statodesian dome is that structural elements can only be removed after careful calculation and strengthening of adjacent structures. So moving a door or window or changing dimensions is possible only after the change in the load-bearing capacity of this area or even the dome as a whole has been calculated.

This technology also has its own assembly feature. The frame must be sheathed as the racks are installed. That is, the second row of racks is assembled only after the first is sheathed, the third row - after the second is sheathed with sheet material, etc. This is due to the fact that in its unfinished form - without cladding - the frame has a high bearing capacity against vertical loads and is not very resistant to torsional loads. Once the edges are sheathed, it becomes very stable and reliable.

Unlike a geodesic dome, a stratodesic connector is not required for assembly. The vertical parts of the frame are connected using specially shaped locks. Horizontal jumpers are attached using a plate, which is fixed with bolts, under which a metal plate is placed.

There is one more nuance that affects the cost of a domed house. When cutting sheet material for a stratodesic dome, more scraps remain than when constructing a geodesic one. This increases material costs to some extent. But they are compensated by the fact that windows and doors are of a standard design, and they are cheaper than triangular ones. As a result, the cost of the dome different technologies not much different.

Advantages and disadvantages

No one will argue with the fact that domed houses look unusual. If you want to have a house or dacha “not like everyone else” and have nothing against frame house construction, take a closer look at this technology. The solution is truly non-standard. In addition, they say it is economical. Price square meter starts from $200. But as you understand, this minimum price. This is an economical option.

Pros of domed houses

Apart from the unusual appearance The advantages of spherical houses are as follows:


Based on the totality of their characteristics, domed houses look very attractive. In addition, many say that construction requires much less money - due to the smaller surface of the walls, material is saved. According to mathematical calculations, the area of ​​the walls is almost a third less. But if there are any savings, they will not be that big - the construction is specific, using specific components that increase the cost of construction. In fact, the cost per square meter is approximately the same as with a conventional form.

Minuses

There are also disadvantages and they are also quite serious. In any case, it is worth knowing about them and taking them into account.


There is also an unusual layout, but it cannot be definitely classified as a disadvantage. I like domed houses precisely because of their originality. So non-standard shape premises - this is rather a feature that must be taken into account when selecting/ordering furniture and choosing finishing materials.

Projects and planning features

It is far from easy to plan a round building in such a way that it is rational, beautiful, and even convenient. There are a few basic techniques that most people follow. The first thing that catches your eye is that there simply cannot be corridors in such a house. They simply have nowhere to lead. This is not bad, but it makes the layout of the house more complicated. Let's start with something simple - how to decorate the entrance to the house.

Entry group

For our climate it is desirable that entrance doors went out into a small room rather than into a large room. In this case, a small vestibule helps. O can be isolated from total area or attached. A covered veranda performs approximately the same tasks. This is a more “civil” way to solve the problem.

Not everyone likes this approach. Today there are other trends in the world - from the front door you enter into a large spacious hall/living room. Such a layout is also possible, but additional measures are needed to cut off cold air - thermal curtain near the entrance. This is done using convectors built into the floor or by installing several powerful radiators near the door. The first method is more effective, the second is easier to implement. All these nuances are typical for domed houses. The only difference is that you will have to rack your brains to figure out how to fit in the built-in vestibule. The other two methods are easier to solve.

Let's look at the device options entrance group with examples. In the picture above, the project on the right, the entrance doors open into the living/dining room. This solution is typical for Europe and America. It is gradually gaining popularity here, but due to the harsher climate it often brings inconvenience - every opening of the door in winter period brings a significant portion of cold air, which reduces comfort.

The option on the left is with an attached vestibule. There are two exits from the vestibule - one in winter Garden, the other is in the kitchen/dining room. The solution is no less modern, but the problem of cold air entering living spaces has been solved. So this idea is worth adopting.

If you decide to make the vestibule built-in, you will obviously have to allocate some area of ​​the house. The minimum is three squares (on the left project). It would be logical if there would be a living/dining room next.

Another way is to highlight large area and use it as a hallway. Place a wardrobe here, a hanger for things “for now” (draft law). If space allows, you can install a small sofa. For a private home, having a hallway is practically a necessity. Dirt and sand are less dragged into the house. And this is another argument in favor of a dedicated entrance group. Attached or fenced off - it’s your choice. But the entrance area is convenient. At least in our realities.

Organization of space

Most often, the central part of the space of a domed house is allocated for a room common use. From this central area you can access all the other rooms, which are arranged in a circle. In general, the central room turns out to be inconvenient, since it is “very walkable.”

You won’t be able to relax in it if it’s a living room, it’s not very convenient to cook in, if you come up with the idea of ​​using this room as a kitchen, it’s also not the best as a dining room the best option. Projects that use this space in this way are presented above. It looks great in the picture, but in real life you can’t count on an intimate atmosphere here. So the walk-through rooms are not the most habitable.

Not the worst way to use this passage area is to install a staircase. After all, most domed houses have two floors, but a screw one just begs to be built here. You just need to take into account that if you simply twist it around a pole, it will be inconvenient to use - the turns will be too sharp. If you design a staircase like a “well,” it will be difficult to build it yourself. So this part will have to be entrusted to someone.

Otherwise, domed houses are planned in the same way as ordinary ones. The basic rule to remember is: to engineering systems were not very expensive, all “wet” rooms are located close to each other. The location of bedrooms, offices and other “dry” rooms is up to your taste.
