The cheapest and eco-friendly house Bashny.Net

I found in network design, which was struck by its simplicity, low cost and environmental friendliness. I must say that this is just the foundation. Doors, windows double-glazed windows, floor heating, heating with gas or electricity - at the discretion of the builder and depends on the hands and creativity. My opinion is that the best option, in the round house is infrared electric heating. But it IMHO.

14 photos + video.





To build such a house must be:
Correct calculations of the geodesic dome.
Wooden blocks certain length,
Thin-walled steel tube, cut into equal pieces that need nadpilit on both sides, or by six, or by five petals. The petals are bent at 90 degrees and drilled under the screws.
Screws.
Straw.
Twine.
Clay.
Bars corresponding length connected to each other, in accordance with the diagram. The framework gives a very tough and durable. In this case, the frame has a diameter - 6 meters (19 feet) This dome can be assembled gang of 3 people for about 2 hours, depending on the type of connector strut.



To reduce the cost of construction, it was decided to combine the geodesic dome structure with bales of straw. The use of straw and clay, as the walls defines a low cost, availability, and low power consumption.



It was dug a hole for the foundation 6m in diameter and 0, 5 m depth. The foundation is a mass of rocks, gravel and sand. Bottom was put perforated drain pipe to drain water into the nearest ditch. Outside frame obkladyvaetsya straw rolls.



Rolls upholstered cord so as not sprawling.



Outside and inside, the first layer coated with a mixture of a liquid mixture of clay and straw.



The first layer is formed using a very fluid mixture, so that it adheres well to the straw.



Only when the first layer is done, you can start with the following.



It is necessary to make all internal and external clay work, before you can start sealing the inner and outer surfaces.



There is a possibility that the straw will start to rot and other problems, so you need to quickly build all that straw is not wet from the rain. In the little moisture there is nothing wrong, but high humidity can cause problems.



The structure of the dome is very strong, it now stands about 3-4 tons. The work is quite tedious and, depending on the weather, if there is rain, it is necessary to cover the dome something to avoid getting wet. In hot weather, the protection is removed, the clay can dry better.



Generally, the first thin layer is needed to the next layer adhered better. In the following, a thicker layer, a combination of clay, sand and straw and fills all grooves voids and cracks on the surface. It becomes smoother



When all the layers will be prepared and dry, the surface is covered in three layers with a mixture of linseed oil and turpentine. Linseed oil penetrates the clay to 5 mm, which is becoming a solid and watertight. The insulation properties of the house are very high.



When the outdoor temperature is 33 degrees Celsius inside the dome house cool.
