One of the main tasks that had to be solved in the North was to provide workers with housing. In 1975, Sokolsky DOZ produced the first famous barrel houses. In the strategic task, the conditions are set for the plant to create a more modern construction of a mobile dormitory for the North than a house car. Round houses-wagons were dubbed "tsubiki".
In 1978, the first mobile residential complex was released on the basis of TSUBOV. The tests took place at the test site and met all expectations. The highest rating was given to the speed of construction, minimum labor costs, reliability in operation, good service and sanitary conditions for living.
"Tsubik" does not look at all like a house in the usual view. Stretched out and placed horizontally, the red-gray cylinder looks more like a railway tank on wheels (or skis, depending on the conditions of transportation). But this is not a whim of the designers, but the seed of an idea that completely solves the problem of blizzards and protects the house from snow drifts.
Snow charges of any density and strength freely flow around a metal cylinder, whose thick triple windows make it look like a deep-sea projectile with portholes. The cylindrical shape, having the smallest possible total surface of the external fences and the smallest amount of heat loss, provides sufficient internal volume of the premises. Concave walls even enhance the effect of "spaciousness" of the premises of the Central Office.
