Located on the hillside of Sesimbra, overlooking Praia do Ouro, the proposal follows the principle of rehabilitation, seeking to ensure the transformation of the existing apartments into larger spaces, taking advantage of the pre-existing structure and volume. Having as guidelines the horizontality, the natural lighting and the connection between exterior and interior spaces (through glass transparencies and the introduction of patios), the intervention searches for the reintegration into the landscape through green roofs with outdoor spaces, some private and others planned for public use.
