ATAH has designed an arts centre in the Chinese city of Shaoxing, which features a spiral staircase opening cut through the building.

The building was designed as the centrepiece of a commercial complex called the China Textile Centre (CTC), which is made up of a series of artistic and commercial spaces.

A spiralling walkway is carved through the glazed cylindrical building, revealing a circulation core that extends up through the centre of the building. The spiralling opening also doubles as a stage.

The Heli-stage's facade is wrapped in curved triangular double-glazed panels. The surface also includes projection technology that can display different patterns or graphics on the building's exterior.

This project has been longlisted in the business building category of Dezeen Awards 2020.
