The refurbishment and extension of this Lisbon building, situated near the Centro Cultural de Belém and the Tagus River, sought to balance contemporary interventions with the preservation of its historical urban fabric. Originally comprising a ground-floor commercial unit and two compact two-bedroom apartments above, the existing structure was characterized by constrained internal layouts and limited natural light. The design strategy responded to these spatial and environmental shortcomings while accommodating an ambitious program for two separate triplex residences.
A two-storey vertical extension was introduced, capitalizing on panoramic views towards the Tagus River and the 25th of April Bridge. This intervention was articulated through a zinc-clad roof, distinguishing the new addition while respecting the rhythm of the retained front façade. In contrast, the rear elevation embraced a more contemporary language, integrating pocket windows to enhance natural illumination and establish a fluid relationship between interior and exterior spaces.
Internally, the reconfiguration prioritized spatial generosity and clarity, addressing the need for larger, more functional living areas. The new layout accommodates two distinct triplex dwellings: the lower triplex features three ensuite bedrooms, while the upper triplex includes two bedrooms sharing a bathroom alongside an ensuite bedroom. The uppermost level of the latter was dedicated to the social areas, optimizing light penetration and framing the expansive river views.
Materiality played a crucial role in reinforcing a sense of timelessness. A palette of wood, stone, and glass was employed throughout, ensuring durability and aesthetic coherence. Custom MDF joinery was specified in natural wood finishes or lacquered in white and light blue, contributing to a refined yet understated interior expression. The introduction of dual access points—through the shared entrance hall with a lift at the front and separate rear entrances—further reinforced the programmatic efficiency of the design.
