In the ventilated façade of the Institut Geològic de Catalunya (IGC), the inner layer responds to the window distribution that the use of the building requires and the outer layer responds to formal aspects. The perforated corten sheet that clads the entire façade provides an abstract image, behind which domesticity is solved. The perforated metal sheet shows a drawing and plays with transparencies: it is a rich composition resource that is possible in multilayer façades.
