Pumacahua Housing is designed by Canda Gazaneo Ungar Arquitectos, located in Buenos Aires, Argentina.
The building is constructed as an overlapping stratum between two dividing plates. Every level shelters four units, except the last one, where the system is altered and appears a substructure that expresses the atypical existence of units inside the set. The whole constructed volume is recessed from the front line, in order to obtain the maximum height permitted. On the front, an access volume gets back to re-compose this line. Each level is composed by four units and a central core linking them. This layout organization, around a court obtains ideal lighting both in the departments and in the access hall. The vertical core finishes off in a metallic structure composed by a bridge and a battery of stairs that forms an ad hoc structure that allows the access to the terraces of each one of the two storey units. The concrete structure, arranged in partitions and slabs without girders, remains absorbed inside the internal and dividing walls between units, and the thicknesses of the slab. The efforts are transmitted directly towards the foundations without any type of transition. Structural engineering by Nicastro Associates.
