With his IN 3 project, architect Jean Verville proposes an architectural 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 sculptural volumes. The gray tones of the raw materials unite into a volumetric entity pierced by an immense golden structure deploying to abolish the hierarchy of spaces. Offering images evolving towards abstraction, this golden ribbon, containing domestic functions as storage units, breaks up space into a single operation of powerful efficiency. The diffusion of a felted and enveloping light invests the place of a mysterious aura that contributes to its theatricality. The rich contrast between the concrete, the sumptuous golden brass and the immaculate brilliance of the white stones, creates a mineral character that encourages a feeling of opulence, intensified by the presence of a triumphant piano. Wandering in this clean and refine space, at the same time of an unusual expressivity, proposes sensations blurring the spatial perception to reveal a sculptural proposal of an extreme sophistication.
