This building has appearance since it has different design that combination from old and new concept. This building has complete departments. This is a solitary building standing on the new, more intimate square connected to the historical park of the Rotunda da Boavista and enclosed by three urban blocks. With this concept, issues of symbolism, visibility and access were resolved in one gesture. This building has good view and environment that make this building feel so fresh and comfortable. This building is also completed with good facilities and security system. To this building so natural and environmental, this building is also completed with green park. Through both continuity and contrast, the park on the Rotunda da Boavista, after our intervention, is no longer a mere hinge between the old and the new Porto, but it becomes a positive encounter of two different models of the city. This building becomes the most green in this city. This building has good and representative hall with good sound system and lights. After researching the acoustic quality of existing concert halls the architect had to conclude together with our acoustic specialist that the best halls in the world have a shoe box shape. It is the most representative hall in the city.
