basis of the compositional solution of the house is a direct heating system of the building spaces. Because of this, with increasing height, the floor area on the south side decreases, which allows sunlight to pass into the northernmost sections of the house. The interior has a very interesting play of light and shadow. Because of the desire for the top and sharp corners in shaping, the project is called "Rock". The house has a wide variety of types of locking: mirrored, linear, with shifts, with courtyards, etc. Mainly on the southern facade there are many selective sun-protection stained glass windows, and on the northern side they are almost absent. From the north, the house is protected from the cold winter wind by a massive wall. To prevent overheating in the house, there are sun blinds that reflect the high summer sun, and the winter sun freely penetrates into the deepest parts of the house due to a large number of two-light spaces. The southern stained glass window is designed at 90° to the winter sun. The blocked house is equipped with thermal arrays (Direct gain). There is also a solar greenhouse-vestibule, where you can plant huge palm trees up to 8 meters high. The facility is also equipped with collectors and a competent air aeration system to save and conserve energy in the house.
