Casa Na Mouraria is a minimalist house located in Lisboa, Portugal, designed by José Andrade Rocha. This house is in the historic neighborhood of Mouraria, Lisbon, and suffered many transformations over the years that compartmentalized the space. The relation with the street was underexplored, and the connections between social and private areas were ambiguous.

The intervention aimed to open the social area to the street, uniting the living room and the kitchen in a gesture that occupies the whole extension of the façade, protecting the bedrooms and allowing serenity or agitation in distinct moments. The preservation and restoration of traditional materials, such as carpentry and stuccowork, were a premise to the project, which aimed to smoothly combine the pre-existing elements and the new ones.
