Thick aluminium sheet cladding. Seven rings measuring 1.3m high and 1m wide go around the building, cross and fuse, creating a compact façade, and separate, forming a cantilever at the entrance to the building. The design of this cladding first focused on the rationalisation of the curves that generate the rings according to objective (maximum dimensions of aluminium sheets, costs, etc.) and subjective criteria (from what radius can a curve be faceted without it affecting the overall perception of the building, etc.). To do this, we created a Grasshooper script that integrates these different variables and generates optimised geometry.
