GWIC provided essential engineering expertise in the transformation of a historic 12th-century building into the elegant Almalusa Alfama Hotel, located at the iconic Arco das Portas do Mar. The five-floor hotel features a restaurant, reception area, and guest rooms, blending modern amenities with the building’s original charm. A comprehensive renovation was required due to the structure’s dilapidated state, with GWIC integrating steel and concrete reinforcements while preserving the original wooden elements wherever possible. With 1,137 m² of carefully crafted space, this boutique hotel now serves as a prime destination for tourists exploring Lisbon’s rich heritage.
