The adaptation of the late 19th-century warehouse into modern office spaces by architect Gonçalo Byrne is a masterful blend of historical reverence and contemporary innovation. Byrne’s vision was to transform the once monolithic structure into a dynamic workspace while maintaining a dialogue with its historical context. The challenge lay in subdividing the expansive, pavilion-like interior and dematerializing the heavy, opaque perimeter walls to invite light and openness.

Byrne approached this by constructing a new body slightly offset from the original boundaries, creating a harmonious relationship with the surrounding environment, including the Garden of the National Museum of Ancient Art. This strategic shift allowed for the introduction of two large, glazed façades that flood the interior with natural light, enhancing the spatial experience and creating a sense of transparency and fluidity.

The design philosophy centered on respecting the building’s historical essence while introducing modern elements that reflect light and openness. Byrne’s use of glass not only dematerializes the structure but also establishes a visual connection with the garden, blurring the lines between interior and exterior spaces. This thoughtful integration of light and space exemplifies Byrne’s commitment to creating environments that are both functional and aesthetically engaging.

Despite its recognition with the Valmor and Municipal Architecture Prize in 2009, the building faces potential demolition to accommodate the expansion of the National Museum of Ancient Art. This decision underscores the ongoing tension between preservation and urban development, highlighting the building’s significance as a testament to adaptive reuse and architectural innovation.
