The house, originally commissioned by Álvaro Siza’s maternal great-grandfather, stands as a testament to Siza’s early architectural vision and his evolving design philosophy. When tasked with its rehabilitation in 1960, Siza approached the project with a focus on creating a harmonious blend of functionality and aesthetic appeal. His design philosophy emphasized simplicity, light, and the seamless integration of spaces, which is evident in his decision to demolish a wall to create a large, open area for entertaining. This transformation allowed natural light to flood the interior, enhancing the spatial experience and creating a welcoming atmosphere.

Siza’s attention to detail is reflected in the careful restoration of the ceilings, walls, and roof, as well as the replacement of windows to improve both the aesthetic and functional aspects of the house. His choice of materials was guided by a desire to respect the building’s original character while introducing modern elements that would enhance its usability. The furniture pieces he designed for the space further illustrate his commitment to creating a cohesive and elegant environment.

In 2007, when the house was acquired by the municipality of Matosinhos to serve as a documentation center for Siza’s life and work, the architect once again took on the challenge of adapting the space. His vision for the conversion was to maintain the building’s historical essence while accommodating its new purpose. Siza’s design choices reflect his belief in architecture as a dialogue between the past and present, where each element serves a purpose and contributes to the overall narrative of the space.

The house’s interaction with its surroundings is subtle yet profound, as Siza’s design respects the existing landscape and urban context. The building’s understated elegance and thoughtful design make it a significant architectural work, embodying Siza’s philosophy of creating spaces that are both functional and deeply connected to their environment.
