In the words of the architect Office for the Metropolitan Architecture (O.M.A.), the new Casa da Música building has ‘an expressive, rock-like shape’. It stands on the Rotunda da Boavista, a square just outside Porto’s historic city centre. The Grand Auditorium will seat 1.300 people, and the Small Auditorium 350. In addition to two concert halls, the building provides (22.000 m2) space for various other functions; e.g. 8 rehearsal rooms with recording fascilities, a restaurant, a music shop, cyber and educational facilities, a parking garage for 600 cars (27.000 m2) and more.

Royal HaskoningDHV was the acoustic consultant for Porto’s concert hall.

Considering the acoustics of the two halls, the challenge was the front and back walls, which are made entirely of glass to give the feeling that the rooms are open to the city. As well as keeping out noise from exterior sources these transparent walls have to be designed so as to contribute to sound distribution within the hall. The glass walls of the Casa da Música’s concert halls have a unique horizontally wave shaped shape. 
In collaboration with Level Acoustics & Vibration and Eindhoven University of Technology the design of the Casa da Música has contributed to numerous scientific and applied studies on stage acoustics, acoustics of ensemble playing and acoustic measurement techniques, which are presented on several acoustics conferences and published as well.
