The E_RC project, designed by the MAPAA firm, consists of the renovation of a 600 m² building located in the Providencia district of Santiago, Chile. The property had been abandoned for more than thirty years, turning it into a disused structure in the heart of the city. The project posed an architectural and urban challenge: how to recover an obsolete volume and transform it into a contemporary residential building.

Located in Iquique, Chile, and developed in 2004, the Quinta Monroy project sought to relocate 100 families who had lived for decades in precarious conditions to the same site. Under the Chilean government's Dynamic Debt-Free Social Housing program, each family received a subsidy of USD 7,500 to build their home. Faced with this budgetary constraint, the Elemental team, led by Alejandro Aravena, proposed an innovative approach.

The Butantã House, designed by Paulo Mendes da Rocha in 1964, embodies a synthesis between concrete as a material and a social conception of domestic space. Framed within the Brazilian brutalist movement—particularly in its São Paulo iteration—this work becomes an architectural manifesto where the apparent structure, functionality, and openness to the environment dialogue with ideas of collectivity.
