Even before entering one of three auditoria, it is envisaged that the Sound Cave will be perceived as a fascinating and flexible acoustic space, which connects Arts Plaza, workshops, foyers, and restaurants. Located in a park within a dense urban high-rise development, the Sound Cave is not only an interior but extends to make connections with the outside, merging with the park and promoting communication between casual passers-by and artists.

The architects call the building the Sound Cave which is described by Ito as a `horizontal and vertical continuous network`.

Having moved on from the more classic formality of Sendai, with its base, middle and top supported by columns, this building will encourage exchange and communication through a more explicitly fluid arrangement of a rich and diverse range of cultural activities. Based on a few geometric rules, the project exhibits more of his recent interest in fluid and continuous spaces, as seen in projects such as the University Library in Hachioji City, and the Crematorium in Kakamigahara (AR August 2007). Toyo Ito extends his interest in spatial complexity in this project for the Taichung Metropolitan Opera House.
