Heritage Britannia Hotel
Lisbon, Portugal
2005–2003
Located in a quiet street just off Avenida da Liberdade, Lisbon’s main avenue, the Britannia is a 1940s hotel designed by prominent modernist architect Cassiano Branco and flawlessly kept by its original owners in all its vintage details.
The project consisted of adding a floor without damaging the quality of the existing facade and interiors. Barely visible from the street, this discreet extension built with zinc roof cladding and solid oak siding, comprises eight new luxury suites with recessed verandas. The waxed cork floor tiles and the lavish Carrara marble bathrooms in the extension were designed as an evocative and contemporary homage to the building’s Art Deco style.
