I would like to offer an illustration. Imagine a house which is well designed from a material or practical point of view... Apart from these physio-functional demands, there are also psycho-functional demands which correspond with our optical, phonetic and tactile experiences. Until now, mankind has attempted to satisfy these 'supra-material' demands with a painting on the wall or a sculpture in a room.... the architecture of the future will have to destroy this duality. Its task will be to express completely and fulfill all our demands.
