The building articulates itself to reveal these functions, and is organised to reflect this as transparently as possible to the outside world. As you move up the building from ground up the increasing degrees of privacy required in the programme positions these elements in a natural hierarchy, placing at the top the most private lounge, and at the bottom the most public exhibition and conference spaces. The atrium cutting through the mass reveals on the other hand all of these functions upon entry, while connecting the building to the street level to the public domain and rising to the top of the whole it also acts as a natural ventilation device for all of the open public spaces. TCA’s basic principle of institutional transparency both conceptual and structural defines the design from the beginning.
