The project locates at the northeast corner of the ChaoyangmenBridge. It consists of a 26-storey main building and an 11-storey annex building. In the main building, there is a of30m-height atrium, glazed with a light-supported glass curtain wall which invites outside scene and makes it transparent without too much glowing sunlight. Emphasized by vertical strings, the façades receive a grand and straight expression. The cascade-like composition of different types of stones implies the extraction process of oil, and further explains the enterprise image of Sinopec.
