Buildings in the country house, made in a non-standard form, decorate the site and increase its attractiveness. Houses, gazebos, greenhouses built in the form of geodesic domes will certainly not go unnoticed. Implementing a small geo-dome project is not difficult at all. Many gardeners can cope with the construction of such a structure, despite the originality of the frame structure. The minimum costs for the purchase of building materials allow you to complete all work in the shortest possible time. Dome technologies are also of interest to the builders of suburban housing. The space inside such a cottage is distinguished by increased functionality. The dome house has 20% more usable area due to a decrease in the number of enclosing structures. On this and it is possible to save building materials.
Architectural structures with a mesh shell as a load-bearing structure appeared in the middle of the last century. The first geodesic domes were designed by Richard Fuller (USA). The American patented his invention. Unusual structures for that time were planned to be erected in order to obtain cheap comfortable housing in a short time. However, it was not possible to achieve mass development using the invented technology.

The extravagant project has found application in the construction of futuristic objects: cafes, stadiums, swimming pools. The landscape designers also paid attention to the geo-domes, who began to place these structures in the center of the landscape composition. Both then and now specialists are attracted by the spaciousness of the domed buildings. By including imagination and imagination, you can find many options for using space within a sphere.
The structure of the geodesic dome is characterized by high load-bearing capacity. The size of the entire area of the structure depends on the size of the diameter of the spherical frame. Small domes of five meters in height are erected without the use of a construction crane by two or three people.
Why is this design better than others?
The spherical shape of the geo-dome contributes to the harmonization of the space, which is saturated with positive energy. Being in a spacious and incredibly cozy round room is good for your health. It is not for nothing that domed buildings are classified as ecological structures. The advantages of lightweight geodetic structures include:
- no need for a solid foundation, and this greatly simplifies and speeds up the installation of the object;
- no need to use construction equipment, which significantly reduces noise during work.
At the heart of the construction of geo-domes is frame-panel technology, which allows, in the shortest possible time, to erect a number of structures for various purposes on a summer cottage or suburban area, for example:
- bath or sauna;
- house or summer kitchen;
- garage or carport;
- gazebo or children's playhouse;
- a pool for year-round use;
- greenhouse or greenhouse, etc.
The main types of geodetic structures
Geocupole designs differ from each other in the frequency of dividing the surface of the sphere into triangles. The frequency of splitting is usually denoted by the letter V. The number next to V indicates the number of different structural elements (edges) used to build the frame. The more ribs are used, the stronger the geo dome will be.
There are six types of geo domes, of which only five are actively used in the construction of facilities:
- 2V dome (the height of the structure is equal to half of the sphere);
- 3V dome (the height of the structure is 5/8 of the sphere);
- 4V dome (the height of the structure is equal to half of the sphere);
- 5V dome (the height of the structure is 5/8 of the sphere);
- 6V dome (the height of the structure is equal to half of the sphere).
It is easy to see that the hemispherical shape of the object is achieved only at an even frequency of splitting.
Scheme of the frame of a geodesic dome of type 2V for the creation of small structures. Ribs of different lengths are highlighted in color and indicated by letters
For small suburban buildings, a 2V dome design is usually chosen. The frame is assembled from two types of ribs, indicated on the diagrams for convenience by the Latin letters A and B, as well as additionally highlighted in blue and red. The blanks are also color coded to simplify the framing assembly process. To connect individual edges of the frame of the geodesic dome, special nodes are used, called connectors. When installing a 2V dome design, three types of connectors are used:
- 4 terminal;
- 5 terminal;
- 6 terminal.
To calculate the length of the ribs and the number of connectors, online calculators are used, into which the initial data of the object are loaded: the radius of the base, the frequency of splitting, the desired height of the dome.
Three types of connectors used to connect the edges of the dome frame that converge at one point (the vertex of the polygon)
Large hemispherical objects with a base diameter exceeding 14 meters are built using 3V and 4V domes. At a lower frequency of splitting, ribs are too long, which complicates their preparation and installation. When building a 3V dome, the ribs are almost three meters long. Assembling a frame from such lengthy materials is quite problematic.
Choosing a different type of dome (4V), the length of the ribs is reduced to 2.27 meters, which greatly simplifies the assembly of the dome structure. A decrease in the length of structural elements leads to an increase in their number. If a 3V dome with a height of 5/8 of the sphere has 165 ribs and 61 connectors, then a 6V dome with the same height of ribs already has 555 pieces, and connectors - 196.
The pile foundation for the installation of large dome structures allows the structure to provide the necessary strength and stability
An example of the construction of a domed greenhouse
Before the start of construction, they are determined with the base area of the future greenhouse, as well as with its height. The size of the base area depends on the radius of the circle into which the regular polygon is inscribed or around which the regular polygon is described. If we assume that the radius of the base will be 3 meters, and the height of the hemisphere is one and a half meters, then to assemble a 2V dome you will need:
- 35 ribs, the linear dimension of which is 0.93 m;
- 30 ribs 0.82 m long;
- 6 five-pointed connectors;
- 10 four-ended connectors;
- 10 six-pointed connectors.
Selection of materials
As frame ribs, you can use bars, a fence board, a profile pipe, as well as special double struts. When preparing ribs, their width is taken into account. If a fence board is chosen, then it will have to be cut into several equal parts using a jigsaw.
Having prepared all the structural elements of the future dome, they begin to level the place for the construction of the structure. In this case, it is necessary to arm yourself with a building level, since the site must be perfectly flat. The leveled place is covered with a layer of rubble, which is well compacted.
Erection of the base and assembly of the dome frame
Next, they begin to build the base of the greenhouse, the height of which, together with the height of the dome, will make the room comfortable for operation. After the construction of the base, they begin to assemble the frame from the ribs according to the diagram, which shows the sequence of the connections. The result should be a polyhedron.
The frame of a one and a half meter hemisphere for arranging a greenhouse in the country is made of wooden bars connected by a connector method according to the scheme with each other
Assembly can be facilitated by dyeing ribs of different lengths in different colors. This color highlighting of individual structural elements will avoid confusion. Isosceles triangles, assembled from bars or pieces of a profile pipe, are fastened together with connectors (special devices). Although small structures can be fastened with self-tapping screws and ordinary mounting tape.
Fastening polycarbonate sheets
Polycarbonate sheets cut in the form of triangles are screwed to the frame. During installation, use special self-tapping screws. The seams between adjacent polycarbonate sheets are decorated, and at the same time insulated with slats.
Arrangement of internal space
Garden beds are made around the perimeter of the greenhouse, while their height should be equal to the height of the base of the frame. When decorating fences, various materials are used. Better and more elegantly combined with plants grown in a greenhouse, natural stone. For convenience, the path in the greenhouse is made as wide as possible. Be sure to equip a place for relaxation, from which you can admire the beauty of outlandish plants and flowers.
The frame of this domed greenhouse is made of a shaped tube. Polygon edges are made of polycarbonate sheets that transmit light and block ultraviolet rays
For the rational use of the internal space, polypropylene pipes are used, which are attached to the edges of the frame. Pots with ampelous plants are hung on these pipes. Low-growing plants are planted at the edges of the greenhouse, and tall ones closer to the center. To maintain a sufficient humidity level inside the dome, a water tank is installed in the northern part of the structure. To enhance the greenhouse effect inside the greenhouse, reflective film, which is attached to the frame structure, located above the water tank, allows.
You can also create a mini-pond from a tire, read about it: https://diz-cafe.com/ideas/mini-prud-iz-pokryshki.html
The interior arrangement of the domed greenhouse is carried out with the maximum use of the available space. The height of plants affects the choice of their planting site in a greenhouse of such an unusual shape.
Arbor in the form of a half-open hemisphere
The gazebo, made in the form of a half-open hemisphere, will become the most attractive place in the summer cottage. This aerial structure is assembled within one working day. The frame is installed from a profile pipe. The diameter of the dome should be 6 meters, and the height of the object should be 2.5 meters. With this size, it is possible to obtain 28 square meters of usable area, sufficient to accommodate friends and relatives. The structural elements of a 3V dome are also calculated using online calculators. As a result of automatic calculation, it turns out that for the construction of a gazebo you will need:
- 30 pieces of ribs, 107.5 cm each;
- 40 pieces of ribs, 124 cm each;
- 50 ribs 126.7 cm each.
The ends of the ribs cut from the profile pipe are flattened, drilled and bent by 11 degrees. For the convenience of assembling the geo-dome lattice according to the scheme, edges of the same length are marked with the same color. As a result, you get three groups of elements that are attached to each other according to the scheme using washers, bolts and nuts. After completing the installation of the frame, the covering material is laid, which can be considered:
- plywood sheets;
- colored polycarbonate sheets;
- soft tiles, etc.
If you close only the upper part of the frame, you get an original half-open gazebo. With the help of curtains, you can decorate the remaining free space on the sides of the gazebo. Your imagination will allow you to achieve an extraordinary design of the domed structure.
You can learn about what to look for when choosing curtains for a garden gazebo from the material: https://diz-cafe.com/dekor/shtory-dlya-sadovoj-besedki-i-verandy.html
Collapsible metal frame can be dismantled at any time. If necessary, the collapsible structure is taken out into the countryside, where it is quickly assembled and covered with a cover made of moisture-repellent fabric.
Or maybe build a whole house?
The house, in contrast to the buildings discussed above, needs a shallow heat-insulated wooden foundation. Corner posts of the base walls, as well as horizontal struts, are attached to the erected foundation. Then proceed to the installation of the lathing of the dome.
The spherical surface of the frame from the outside is sewn up with plywood sheets, the thickness of which must be at least 18 mm. Windows and doors are installed in the selected places. To insulate the structure, thermal insulation materials of a new generation are used, which from the inside are also covered with sheets of plywood or other finishing material.
The material on the stages of construction of a frame house will also be useful: https://diz-cafe.com/postroiki/dachnyj-domik-svoimi-rukami.html
The construction of a country house in the form of a geodesic dome is carried out using heat-insulating materials laid between the internal and external finishing of the double frame
For quick fastening of all materials, it is recommended to use a system of double struts when building a country house.
As you can see, every gardener can find an application for a geodesic dome in a summer cottage. If you cannot build such an original structure on your own, then hire professionals. Many builders are happy to take on such projects, because they can be built in a short time.

Polycarbonate dome greenhouse
A stratodesic dome is a dome-shaped structure consisting of an arched frame. A geodesic dome is a hemispherical structure. It does not require a foundation due to its low weight. You can build a geo-dome with your own hands alone. This dome maintains the right climate for many types of plants, allowing plants to be grown year-round. Due to the round shape of the structure, the soil is heated.
The structure of this shape can be used in different ways. Most often, dome-shaped structures used for gazebos... Can be used as a barn or a private house. For the construction of a private house, this form of construction did not become popular among the people. Not everyone dares to install a dome-shaped structure, although it has an interesting design and a very solid construction.
For those who like to experiment with the structure of the dome shape, they will like it. The structure consists of beams of different lengths. The choice of domed buildings on the building materials market is huge. You can choose any size.
There are not many disadvantages to such a wonderful design. It is necessary to make a rather large greenhouse, more precisely, to take a large diameter of the sphere, so that it is convenient to work inside, straightening up to its full height. In addition, it is most likely problematic to arrange racks for multi-tiered beds. You will have to be content with one level, and tall plants need to be placed closer to the middle, and low ones around the perimeter.
It is possible to assemble a geodesic greenhouse with your own hands, but it is difficult to independently calculate the dimensions of all elements and build drawings. Not everyone has the opportunity to build frame frames at home. You can, of course, order drawings from specialists, as well as the manufacture of segments, but such a step will significantly increase the cost of the entire product. Perhaps this, along with the forced economy of space, explains why such greenhouses are not very common in our summer cottages.
Another difficulty in assembling a greenhouse with your own hands is that such a large number of joints must be made with a high degree of accuracy in order to ensure the necessary sealing of the building.
If you wish, you can buy a ready-made greenhouse, collect it on the site, grow berries and vegetables in it, or turn it into a winter garden and a greenhouse for exotic flowers.
How to position a greenhouse on a personal plot
The location of the greenhouse on the site is an important factor affecting the growth and development of plants. The yield of the crops grown directly depends on it. In this regard, it is extremely important to know how to properly position the greenhouse on the site, where the vegetables will grow well.
How to efficiently locate the greenhouse on the site
To create favorable conditions for growing plants and increase yields, it is necessary to correctly position the greenhouse.
For the correct choice of the construction site, take into account:
- Qualitative characteristics of the soil
- Features of the relief
- Direction of the wind
- Location of communications and other buildings (barn, garden, etc.).
The quality of the soil plays an important role. A greenhouse installed on soft soil can sink or tilt. Because of this, the structure will not be as strong, damage to the coating or frame, disruption of the door structure is possible. Therefore, it is necessary to choose a place with dense soil. If this is not possible, then the foundation is poured.
In swampy areas, drainage must first be performed.
It is also not recommended to make a greenhouse or greenhouse in a clay area. This is because the clay will hold water when watered. High humidity is not a variant of the norm for all plants. It is best if there is sand under the fertile layer of earth. If there is no sandy area, then you need to remove the clay layer, make drainage, sandy and fertile layers.
It is necessary to check that there is no groundwater on the site or that it is no closer than 1.5 m.
Polycarbonate greenhouse space
When choosing a location for a polycarbonate greenhouse, it is also important to consider the sufficiency of lighting. The lack of this characteristic will lead to additional costs. First of all, it is necessary to use the southeast and south sides, as they will provide the plants with the level of natural light necessary for their growth.
For the greenhouse, it is possible to use the immediate vicinity of low trees as protection from the heat. The presence of such a neighbor will save the leaves of the plant from burns.
It is not recommended to install the structure on a slope. Slope is unacceptable. You can remove this flaw by building a foundation. At the same time, a slightly sloping area to the south is favorable for greenhouses, but it is not worth considering to the north as a place for a greenhouse.
Bad if you place:
- Near fences
- On the slope
- Near a large and tall neighboring building.
This is due to the fact that fences and structures will constantly shade the plants in the greenhouse. The level of illumination in the greenhouse, the ability to save on energy costs, depends on the correctly chosen location of the greenhouse.
A polycarbonate greenhouse is good to install on a hill. This will prevent flooding of the main structure and seedlings during precipitation and melting snow.
If there is no other option and the structure must be built in a lowland, then an auxiliary layer of soil must be put on the garden bed.
Efficient greenhouse on site
Sunlight promotes the growth of plants, the accumulation of vitamins and nutrients in them. If, after all, there is no place with very good natural light, then the greenhouse is built in such a way that it is illuminated in the morning.
Thus, the heat received in the morning will remain in the building longer. It will be warmer there at night. Moreover, when the plants are constantly under the scorching sun, sheds are made.
There should be doors on the side parts.
To ensure maximum yield, the greenhouse is placed in a place that:
- Well lit by the sun's rays
- Protected from gusts of wind
- Where there is no cold wind currents.
Cold winds inhibit or reduce the accumulation of heat in the greenhouse. Wind gusts can damage the greenhouse structure. Placing the greenhouse close to the south side of the house, along a fence or hedge, will protect the greenhouse. Buildings should rise no more than 2-2.5 m. They will be able to disperse powerful air currents and the wind speed will decrease.
It is recommended to install the side parts of the greenhouse from west to east.
A greenhouse is not built near tall trees and bushes at all, since they can shade the structure, stain with drops during rain, tear the film or break glass during gusts of wind.
If possible, the territory needs to be prepared. It is cleared of disturbing trees or shrubs. It is also necessary that plants from the neighboring garden do not violate the boundaries of the site on which the greenhouse is planned to be located.
For example, raspberries or blackberries are uprooted.
Along with other parameters for location, soil relief is taken into account on the site. The best place to set up a greenhouse is on a flat area with solid ground.
There is high humidity in the lowlands, so this is an unfavorable place for the location of greenhouses. It is better to find an area with dry soil. One of the main parameters taken into account is the ability to approach the greenhouse.
This is due to the fact that it is necessary to take care of the plants in the greenhouse: water them, weed them, etc. Nothing should interfere with this.
Tips: how to properly install a greenhouse on the site
There is an algorithm of actions for installing a greenhouse on the site. Compliance with it will ensure high-quality fixing of the greenhouse structure. Allocate the installation of a greenhouse with and without a foundation.
The installation of a lightweight polycarbonate greenhouse without a strip or point foundation is suitable only for seasonal use of the structure.
It is not as warm as needed for year round use.
A greenhouse without a foundation is not intended for growing vegetables year-round.
The disadvantages of installing a polycarbonate greenhouse without a foundation include heat loss (up to 10%) and the absence of a barrier for pests in the upper soil layers. The first disadvantage is significant when it becomes necessary to additionally heat the greenhouse. The use of electricity, gas and firewood requires additional costs.
The advantages of a simplified version of the greenhouse, when used in a summer cottage from May to September, are the following:
- Freeing up time and money that does not need to be spent on pouring the foundation
- Installing the greenhouse yourself with the help of 1 person
- Dismantling the structure after the end of the season
- It can be moved to another location.
If it is impossible to put two greenhouses on the site, but it is necessary to periodically change crops in, then the option without a foundation will be most suitable. You can place structures on T-shaped legs or on a support buried in the ground.
For use in the country, the first option is the best. It is best to install the greenhouse on the ground or on the foundation in the fall or early spring. At this time, nothing interferes with the installation.
To install the greenhouse, the temperature should be 10 ° C, cellular polycarbonate does not burst when tightening the bolts, as in the cold.
The manufacture of a greenhouse includes such work as the installation of polycarbonate coverings, the arrangement of vents, ends, sides and doors, the installation of devices that prevent the penetration of pests. This algorithm is subject to change if you need to take into account some other factors, for example, the terrain.
The best place for a greenhouse
The best place for a greenhouse is a flat piece of land. In this case, you can level the area. For this, planning is carried out. The key to alignment is not to overdo it.
This is due to the fact that the soil can be strongly compacted, and this will worsen its composition and have an extremely negative effect on yield. For a winter greenhouse, the northern part is made higher by 150.
This will help the greenhouse to get the best possible light and keep the warmth from the sun longer.
The place for a greenhouse will be favorable if the preparation is followed:
- Distance of 3 m between buildings on the land and the greenhouse
- Orientation of the side walls of the greenhouse to an east-west diagonal to provide plants with warmth from the wind plying in this direction
- The meridional location of the ends (north and south)
- Maintaining a distance from vegetation that can shade the greenhouse and take nutrients and water from greenhouse crops
- Draft-protected place.
Expert's answer: how to place a greenhouse on a site (video)
Therefore, it is important to choose a good location for the greenhouse installation. This will increase the yield of crops planted in the greenhouse. To do this, you need to take into account a number of factors.
These include terrain, soil properties, illumination level, wind direction and others. An ideal place for a greenhouse is an area that is not shaded by buildings and plants. At the same time, such a place cannot always be found.
The existing deficiencies are being corrected. For example, you can put a fence against drafts, level the area of the site.
