Abstract: The invention concerns a supporting framework, in particular for house furniture, the framework taking the form of a rectangular grid structure consisting of load-bearing vertical supports and horizontal adjustable panels (4) inserted between the supports. Preferably, the furniture constructed from the kit also comprises adjustable units which are provided with movable door and/or window elements (5) and are accessible from the front, the back of the units generally being closed by a rear panel which covers the entire area and, as well as providing greater protection from dust also increases rigidity at the corners of the furniture. The supporting framework comprises ladder-like supports, which consist of at least two--or in the case of furniture with a graduated cross-sectional shape generally of three--pre-fabricated vertical uprights (10) extending parallel at a spacing from each other.
