The new Apprentice Formation Center is a compact and economic building. It achieves the composition of the buildings of the House of Crafts of the Val-de-Marne Department, near Paris. The raw yellow concrete facade gives a clear identity to the building. It comes down on the ground and back up again the previously existing building, creating an open air sunny room, a generous public space linking the old and the new. On the existing building, the concrete defines an extension of the cafeteria. In a game of inversion, the new building backs its concrete facade and is based on a complex steel structure. The long span (20m) of the plumbers workshop is assured with full height beam that frames the second floor. The triangulations of these beams give the diamond shape of the upper level windows and the inclination of the zinc.
- Creation of a new three level building : double-height hall, double height plumbers workshop, classrooms, meeting room with good natural light - Rehabilitation of the existing : creation of a cafeteria, refurbishing of classrooms and offices.
ENVIRONMENTAL APPROACH : - Raw concrete tainted in mass - External insulation - Roofing planted - Recovery of rainwater from draining valley - Solar panels on the roof for hot water - Management of waste water and energy - Exclusion of PVC (aluminum frame / wood, zinc and polyethylene tubing) - Solvent-free paints and water waste management - Materials with low embodied energy
