Acha Housing Units located in the Mariano Acha Street, represents an investigation developed throughout theprojectabout two themes of great importance for us when the opportunity of operating on traditional lots in the city appears, implying a collective housing program.
These themes are: the revision of the latent possibilities of the lots between party walls, and the material expression of the buildings.
The volume of the building, from the third storey upward, rotates the traditional lot’s logic of Buenos Aires, giving place to a lateral façade, which coincides with the best orientation and views, taking advantage of the lower heights of the neighboring buildings and the presence of the Zapiola square.
The building combines different housing typologies that refer to distinct urban ways of inhabiting; from more introspective units, to flexible units that admit uses apart from the traditional use of inhabitation, and units with large places linked to life with more outdoor connection.
The Acha Housing Building is a new chapter that intends to contribute to the revision on the extense problem of housing buildings in cities with an increasing density.
