Abstract: A bulding system for building movables formed one or more individual parts and modules. The module system is constructed on a frame (1) formed of four profiles (2, 3, 4, 5) which are joined in order to form a rectangle (7). Mounted on the frame are supporting rails (8) in which base cabinets (9) may be hung and table tops (10) may be mounted. By means of further devices which interact with the frame, it is possible to extend the system to provide top cabinets. Furthermore, the system may be equipped with technical installations and other utilities for use in connection with the work at the system, and the system may be equipped with covering, side and base panels.
