The imposing wall stands before us. It’s a testament to the ingenuity of Álvaro Siza Vieira. This is Casa da Bouça a remarkable housing project in Porto.
Built between 1973 and 1977 and later completed in 2006 Casa da Bouça is more than just apartments. It’s a response to a critical need. The Serviço de Apoio Ambulatório Local SAAL an organization formed after the 1974 Portuguese Revolution sought to improve housing conditions. Siza’s design is a direct result of this initiative.
The location itself posed challenges. Casa da Bouça sits near an elevated railway embankment. The noise pollution was considerable. Siza addressed this with a double wall a clever solution that protects the homes from the constant sounds of passing trains. This wall isn’t just functional. It’s a structural element defining the entire project.
The initial plan was grand. It called for four parallel rows of three and four-story buildings. These rows would create narrow courtyards. Community facilities a laundry a library and meeting spaces were planned. They would form the southern end of each row. Unfortunately only a portion of the two eastern rows was actually built.
Casa da Bouça’s design is a unique blend of modern architecture and local building traditions. The simple geometry the white plaster walls and lack of ornamentation are typical of modernism. Yet Siza’s use of materials and the incorporation of terraces at the top floor reflect local building styles. The building’s volume is intentionally eroded at the top floor to avoid the feeling of a heavy massive building.
The apartments themselves are thoughtfully designed. The lower maisonettes offer 80 square meters of space. The upper apartments are slightly smaller approximately 74 square meters because the building steps back on the top floor. There are two types of windows tall narrow French-style windows in living areas and hopper-style windows near the stairs.
Casa da Bouça is more than just housing. It’s a testament to the power of good design to overcome difficult circumstances. This project also shows the collaboration between architects residents and the state. Even though the initial vision wasn’t fully realized Casa da Bouça remains a shining example of Álvaro Siza’s talent. It’s a reminder of how architecture can shape not only our physical environment but also the social fabric of a community.
