the designers of vincent coste architecte have completed a 200-meter residential structure called ‘A3 house’ in toulon, france. the plan of the villa is organized within the confines of a triangular volume. it has a double vision, meaning that it simultaneously opens towards the bay of sanary and the harbor of toulon. the idea was to orient each space on both panoramas, hence the shape allowed the architects to develop a greater frontage of 35 meters long. towards the front of the dwelling, the sleeping areas and service functions meet at a perpendicular intersection to shield the public spaces from the road.

custom-designed library created separating between circulations bedrooms and the lounge

a corridor from the entry leads to the living room, kitchen and master bedroom. as residents circulate they are presented with a zig-zagging edge formed by a series of partitions changing from solid to glazed, depending on the corresponding interior activity. the sharp corners are oriented in a manner that provides perspectives of the sky ranging from sunrise to sunset. from here, continuity is developed by the ability for each room to open as a subspace of the summer room, outdoor kitchen, and jacuzzi. conversely, the private zones are rotated towards the entrance façade and the interior garden. the entire complex is clad in extruded terracotta custom-designed by les rairies montrieux for the project.
