Located in downtown Lisbon in the DGPC's Urban Rehabilitation Area and Property Protection Zone, this multi-family housing building has been subject to various extensions and alterations over the years, depriving it of its original character and historical identity.

​Behind a plain metal façade that does not reveal any interior organization, the building hosts six housing units in three stories.

The central concern of the Feld 4 housing cooperative was the creation of spaces for collective living with intensive, neighborly interaction in the sense of a family house community.
