The main fa├žade has a very simple design, which allows us to develop high technologies with very simple means: clay spheres of different sizes form a long series of adjustable belts which shade the interiors in summertime, casting beautiful decorative shadows, and act as massive wall heating in wintertime. This way, harmful emissions are reduced as much as possible by exploiting local natural resources, passive heating and natural cooling.

The succession of spheres with different sizes creates a pixel-based curtain wall with a wide range of possible patterns inside a basic orthogonal grid, opening up new opportunities for the traditional decorative patterns to express themselves.
