The house is designed in the historical center of Alcobaça and is a record of different time periods. It is a small building reconstructed to maintain the vernacular language. A wall is added to the renovation and is shaped to house a protected extension. On the existing building, a void is created using the thickness of the peripheral walls. A space is opened, lit from the skylight above that creates a private and protected atmosphere. Through the reinterpreted windows in the facades, a connection is made with the exterior, creating unexpected internal spaces. The extension of the house exists between the two levels: the street level, and the garden, which is generated overseeing the Baça River. The form of the new wall defines the courtyards that direct views to the building’s exterior. The social areas work as a continuous space that spread through the two elements of the intervention.
