The Housing Complex Los Andes was made by the architect Fermín Bereterbide in 1927. It’s a group of multifamily housing that occupies the entire block in a "hof" typology, typical of northern Europe. It was originally destined for social housing. Over the years the population was replaced by middle-class families because of its high quality spatial qualities and construction. Nowadays its occupied by families who enjoy community life generated in its semi-public spaces and who know the history of the building, transforming it into a place of worship. The apartment that we remodel had been transformed previously and in general it was in good conditions. Besides general arrangements and enlarging the principal bathroom, the most important thing was to generate 2 studios, one individual and one for teaching, and a great library of 135ml of books. The larger study is separated from the living room by mobile libraries, which lets you enlarge the living room when is not in use for classes or study groups.
