Abstract: The present construction includes outer walls, roofs and/or floors in the form of an assembly of modular units. Each modular unit comprises a peripherally closed rectangular supporting frame with intermediate frame elements, several open compartments having all the inner breadth of the supporting frame and having respective heights equal to an integer submultiple of the height of said frame or to an integer multiple of said submultiple. Construction elements including a central embrasure part are arranged in said compartments and at least two facing parts are placed, respectively, on opposite sides of the supporting frame and fixed to the central embrasure part and/or to the supporting frame.
