In the heart of Lisbon, on the corner of Rua do Passadiço and Travessa de Santa Marta, this project combines preserved historic facades with a contemporary four-story extension. The ground floor includes two commercial spaces, and the upper floors offer seven apartments (from studios to two-bedroom units) with natural light and modern layouts. Balconies, stone details, and discreet mansard windows ensure elegant integration with the surrounding architecture.
