Architecture, Building and Structure Design Tiangang Art Center Gallery by Syn Architects Tiangang Art Center is a renovated building in Baoding that houses art galleries, a hotel and catering services. The project covers 2586.95 square meters and reuses an original semi-circular concrete frame structure that had been left unused. The main body is coated with white granular paint to keep the color pure, giving the clean geometric form the look of a large object that catches sunlight. A curved skylight spreads even daylight through the main spaces, creating changing light and shadow during the day. The center serves as a gathering place for artists and art events.
