PCF House is a minimalist house located in Sante Fe, Argentina, designed by Pérez Cepeda, Francesconi. The proposal is based on the interpretation of particular conditions and lifestyles developed over a process of inhabiting the place, marked by relations of a natural adaptation to climatic, socio-economic and cultural characteristics. The concept of physical and cultural pre-existence is therefore essential to ensure the success of the house in its capacity to create spaces for man’s relationship with his intimate environment, and social relationship on a larger scale.
