Located in the middle of its block, Ferreira Borges 181 building is in the protected zone around the Águas Livres Aqueduct in Lisbon. The intervention aimed at recovering this historical building and reframing its presence among neighbouring buildings with respect to material, colour and mass.
The eight-unit residential programme consists of two duplex apartments on the ground level (T1 and T2); two apartments on each of the second and third storeys (T0 and T1); an entire apartment on the fourth storey; and a two-storey apartment duplex over the fifth and sixth floors (T3).
The extension of the building consisted of three new floors, responding to the programme and enhancing volumetric coherence with the surrounding streets and the urban block. The form of the extension maximises natural light in the dwellings and creates a visual link with surrounding buildings.
For most of the exterior restructuring, original materials and finishes which characterised the building and its construction type were maintained and renovated, such as the ceramic tiles distributed across the façade.
Along with the architectural design, Fragmentos was also responsible for the engineering project. The challenge here was to accommodate the new number of apartments with structural reinforcements and advanced technical features adapted to contemporary needs while respecting and enhancing the existing heritage. Each space was designed to be unique, with distinctive thermal and acoustic solutions. With a strong sense of place in mind, this refurbishment project involved several distinct disciplines to confidently form the centrepiece of this urban block’s regeneration.
