Palácio do Tejo is a paradigmatic example of architectural rehabilitation, where the preservation of historical heritage engages in dialogue with contemporary solutions. Situated between the Alfama hill and the Tagus River, the building reflected layers of different periods and functions, presenting a complex constructive stratigraphy that required an in-depth archaeological and architectural study prior to the intervention.

The rehabilitation project was guided by a deep respect for the building’s identity, ensuring the preservation of structural and decorative elements of significant heritage value. The main staircase, the vaulted gallery on the ground floor, wooden floors, stone masonry, wrought iron railings, balcony balustrades, a central stone pillar, and tiled wall coverings were all carefully restored.

The architectural approach focused on recovering these features without compromising the building’s integrity while incorporating contemporary solutions
to meet current functional and living standards. The intervention respected the pre-existing structure, minimising alterations to the volumetry and spatial organisation. The ground floor was maintained for commercial use, while the upper floors were converted into residences, arranged around the original courtyard, evoking the atmosphere of traditional Lisbon villas.

The introduction of dormer windows and small terraces improved natural lighting and ventilation, fostering a stronger connection with the urban surroundings. Sustainability and energy efficiency were fundamental principles of the intervention, prioritising construction solutions that ensure thermal and acoustic comfort
without compromising the building’s historical authenticity. This approach integrates Palácio do Tejo into the city’s rehabilitated heritage, enhancing Lisbon’s architectural and urban memory.
