Guangzhou Circle Mansion has a total floor space of 85,000 sq m (914,000 sq ft), spread over 33 floors, and is 138 m (452 ft) high, with the circular hole measuring 48 m (157 ft) in diameter. The building currently serves as home to the Guangdong Plastic Exchange, and also hosts several exclusive office units, plus a hotel.
