What is space in architectural terms? Gino Valle relied on a spatial grid of 165x165cm to regulate all spatial relations of Giudecca’s Social Housing complex. Our installation aims to exhibit the process of abstraction and rational control over the space that happens in the architect’s mind. Our goal is to expose this process in the real world, showing that the lines once drawn on the paper are not only symbols, grammar, language, but they ‘are’ space, they ‘are’ architecture. Lines and distances become squares, walls, structure, room sizes, alignments and imperceptible void boundaries that host our existence and shape our perception of space.
