Spiral is an urban art center, where fine arts and design exhibitions, music, and stage performances can take place in a variety of settings. A continuous circular space winds through gallery spaces, a café, an atrium and an assembly hall, creating a "stage" for people to see and to be seen, interacting with each other and with the artwork. The exterior facade, built up and composed from smaller details, reflects the complex program. On the interior, detailing is used more rhetorically, rather than simply continuing the exterior themes.
