Self-standing, thermally-insulating, noise-insulating, seismically-insulating, water-insulating, electromagnetic-insulating superstructure, whose overall internal volume is filled with rigid and lightweight granules, in which the dwelling rooms are immersed. The lightweight granules are spherical, porous or hollow, they have no binder and are scattered. A gas-tight skin clads all the outer surface of the superstructure's shell and the walls of the dwelling quarters. Gas-tight bay-frames of conical outer shape are embedded in the openings and bays. The entire volume, made up of the scattered granules, the plates, the bay-frames and the gas-tight skin, is under gas-vacuum. This gas-vacuum is lifetime-controlled by a vacuum pump which is installed in situ. The outer casing and the inner walls are braced by the volume of granules stiffened by atmospheric pressure. A plurality of ion-polarized layers, vaporized on overlay metallized polymer vacuum sheets, are inserted between the rigid plates and the gasproof skin.
