The proposal, which was selected from a competitive pool of entries, includes three new housing blocks that will provide 100 new dwellings. The buildings are located in a premium area of Lisbon, near the historic Basilica da Estrela and along Infante Santo Avenue. Housing, commercial areas, and two generous public spaces open to the city are designed for a total of 20.000 m2.

The proposal’s design integrates the new buildings with the city’s heritage and urban fabric while providing much-needed public spaces. The two public spaces, a lush green garden, and a stable paved square, are designed to be inviting and to enhance the urban experience.
The interior layout of the housing blocks is based on a modular structure, providing a range of housing options from one to four-bedroom units. The flexible units can accommodate changing family dynamics and foster a sense of community. The 100 residential units are divided into innovative typologies developed around a repeating base module. The intentional design flexibility of open-plan living, dining, and kitchen areas enhances social interaction, while also allowing easy separation for privacy.
The proposal emphasizes sustainable and circular design principles while embodying credible and feasible construction models that prioritize the physical and psychological well-being of residents and users Passive strategies are integrated into the buildings and public spaces, including rain gardens, tree-lined edges, and measures to reduce visual and noise exposure.
