The Ferreira de Castro office building, a masterful transformation of the former Oliveira de Azeméis school, stands as a testament to innovative architectural design in the heart of Oliveira de Azeméis. The project, envisioned by Álvaro Siza, sought to breathe new life into the structure while respecting its historical essence. Siza’s design philosophy, rooted in the seamless integration of form and function, is evident in the building’s thoughtful restructuring.

The ground floor, once a bustling educational space, has been reimagined as a vibrant commercial center, inviting the community to engage with the building in new ways. Above, the three-storey volume has been meticulously converted into modern office spaces, each floor offering a unique spatial experience. The transformation required significant structural alterations, including the reinforcement of vertical structures and the demolition of existing beams, to create open, flexible work environments.

Siza’s vision extended beyond mere functionality; he aimed to create a dialogue between the building and its urban context. The design incorporates ventilation patios, allowing natural light to penetrate deep into the interior spaces, enhancing the connection between inside and out. The partial extension of the second floor not only maximizes usable space but also respects the building’s original silhouette, maintaining harmony with the surrounding architecture.

The choice of materials reflects Siza’s commitment to quality and durability, with a focus on creating a timeless aesthetic. The building’s interaction with its surroundings is further enhanced by its proximity to the Pinto & Sotto Mayor Bank, another of Siza’s creations, establishing a cohesive architectural narrative within the cityscape.

In Siza’s own words, “Architecture is about transforming reality, not just replicating it.” This ethos is palpably realized in the Ferreira de Castro office building, where every design choice serves to elevate the structure’s purpose and presence within the community.
