To expand its already existing retail area, situated on the central city square, Marks and Spencer acquired a derelict 18th century house in the narrow Strait Street of Valletta. It was envisaged that the two spaces would be connected by a bridge. However, the unsuitability of permanent bridges spanning across the street, forced the architectural team to come up with an alternative means of joining the two areas. The team decided on a semi-permanent bridge, inspired by the traditional Maltese balcony. The bridge is encased within two balconies facing each other. Due to the narrowness of the street it was possible for the traditional proportions of the Maltese balcony (0.9m wide and 2.7m high) to be reestablished and for the two halves of the bridge to meet. During shop hours, the bridge mechanically unfolds through a series of mechanical winches and pistons that lower the floor, raise the roof, and unfold the sides. This allows access from one shop to the other. Together with the cafe located at ground level in its shade, and the retail outlet itself, the bridge has helped a run-down area of the capital city.
