Despite the attempts to escape the shoebox-shaped auditorium, experience shows that this type of concert hall offers the best acoustics. In this case, the design chosen reinterprets the type, redefining the relationship of the concert hall with the exterior. Winner in the competition held in 2001, the project adapts the Y2K house, designed a year before for a millionaire, to the brief: an angular geometry into which the regular prisms of the essential program are excavated.

On the historic Rotunda da Boavista, along an axis joining the center of Porto and the sea, the auditorium is set back, resting on a more intimate square, and rises as a freestanding object, addressing issues of access, visibility and symbolism in one gesture. Like in a spacecraft, a slender stair of access leads to the lobby, where steep stairs connect all the spaces: restaurant, terraces, technical spaces and vertical communications. Through these spaces one reaches the main public functions, carved out of the building’s mass, and which include two concert halls. The dynamism of the residual space is counteracted by the boldness of the main concert hall, with capacity for 1,300 spectators.
