An architecture office based in Lisbon that collaborates on a regular basis with other architects, urban planners, designers and engineers on the production of architectural and urban projects. The work explores the definition of architecture as a system of relations between private and public, individual and community, interior and exterior. An open system that enables its users with multiple possibilities of occupation. The office took part in several exhibitions, including the 2012 Venice Biennale, and has been awarded in several international competitions.
