The A3 House in Toulon, France, is a villa designed by Vincent Coste Architecte. The house is organized within the limits of a triangular volume, being simultaneously opened towards the Bay of Sanary and the harbor of Toulon.
From the entry, there is a corridor that leads you to the living room, kitchen and master bedroom. The way the sharp corners are oriented is meant to provide perspectives of the sky changing from sunrise to sunset. Each room has the ability to open as a subspace of the summer room, outdoor kitchen and Jacuzzi. As a contrast, the private areas are rotated towards the entrance facade and the interior garden.
