K.Melnikov's House in Krivoarbatsky pereulok in Moscow, 1927-1929. An experimental house, "a play of pure constructions" that confirmed in practice several complicated artistic-compositional and constructive methods. For example: a brick wall skeleton frame made so that some 200 hexagonal apertures were formed in the outer walls that could be bricked up or left as windows. This made it possible to change the arrangement of windows at will. The architect refused from the rectilinear plan in favor of curvilinear character of the walls to achieve artistic effects in the interior. Nearly all the rooms in the house are sectors in form.
