With his IN 3 project, architect Jean Verville proposes an architectural domestic installation juggling with excesses and exuberance while retaining its signature of an assumed minimalism. The proposal calls for mechanisms of perception of space that break the usual patterns of domesticity. In order to satisfy the needs of everyday life, but also to subtract them from time to time in order to create a working environment that strengthens the maestro's concentration, the bare space skillfully conceals functions in a succession of brass sculptural volumes in a complete gray environnement.
