This project corresponds to the previewed extension of the House in Cruz de Oliveira, which was conceived as an evolving project, according to the growth of the household. According to the initial project, the new annex for the bedrooms changed and aligned with the first building, creating a courtyard in the back of the house for the master bedroom. This bedroom is also characterized by its great transparency, since it offers two facing exterior doors. A metallic beam separates the external doors for the two other bedrooms, simulating an uninterrupted window. Inside, a series of hidden panels serve as doors, emphasizing the corridor that runs through the whole house.
