On the one hand, the blind wall of the first floor is driven by plants that take root on top of the roof of an annex. On the other hand, a volume in metal seems to fall and defy gravity. This volume terrace catches the light and reflects it to the pool adding brightness, life in the north garden often in the shadow of the house. It breaks the symmetry of the two existing annexes and discusses with the canopy that opens to the sky (sky vs. earth).
