The Caixa Geral de Depósitos bank branch in Arraiolos is a striking example of modern architectural ingenuity, seamlessly integrating with its historical surroundings while offering a fresh perspective on urban design. The building’s narrow and deep structure, which spans an entire block, is a testament to the architect’s vision of creating a harmonious blend between the old and the new. The site, once a bustling fish market, now hosts a space that is both functional and aesthetically pleasing.

The architect’s design philosophy centers on the interplay of light and space, evident in the building’s interior dominated by an extensive transverse balcony and a cubic volume housing the manager’s office. The zenith light entrance is a masterstroke, flooding the interior with natural light and creating a dynamic atmosphere that shifts throughout the day. This focus on natural illumination not only enhances the user experience but also underscores the building’s commitment to sustainability.

The main elevation of the building, with its enigmatic and abstract appearance, is a clever solution to the challenges of urban continuity and interior lighting. By aligning with the adjacent structures, the building maintains the historical streetscape while introducing a modern aesthetic. The use of materials further accentuates this balance, with a façade that reflects the textures and tones of its surroundings, yet stands out with its contemporary design.

Inside, the spatial experience is one of openness and fluidity, encouraging interaction and movement. The architect’s vision was to create a space that is not just a bank but a part of the community fabric, inviting and accessible. This is achieved through thoughtful design elements that prioritize both form and function, making the Caixa Geral de Depósitos branch a landmark of architectural significance in Arraiolos.
