Abstract: The present invention relates to a novel, sustainable, flexible, modular, reusable constriction system, which can be used as a vertical or horizontal space-enclosing element (FIG. 1) or can functionally extend existing space enclosures as a lacing shell (FIG. 6). The system consists of a combination of height-adjustable braces (FIG. 3) with integrated shop construction system and modular covers with variable surface, structural and material design, which are connected flexibly and reversibly to the braces via a bonding system (FIG. 2). The system can be set up, dismantled, and modified without damage to the surrounding components and without a mechanical mounting on surrounding components. The system can compensate for flexing of adjacent components using a spring mechanism (FIG. 4). It can therefore be adapted to changing needs of a user (corporate identity, corporate design, “wall as furniture”, position of the installation outlets or installation routing) in a “plug-and-play” manner (FIGS.
