P house is a puzzle. Three volumes rotated around one nucleus. The program boasts three floors: a garden, a terrace with fireplace and barbecue, home theater, dining and living rooms, washroom, kitchen, four bedrooms, office and family room. In the basement: a garage, laundry room, utility rooms and a gym. The nucleus of the circulation is made of a continuous staircase joined in a structural wall. This block, which organizes the structure and distributes the fluxes, is the pivot around which the boxes revolve. The result strengthens interactions, the crossing of eye views and vectors through the garden.
