This ten-story office building is located in a densely built section of Hangzhou, adjacent to a park. Placed above street level, and set apart from surrounding buildings, the slim building has greater presence than might otherwise be the case. The facade is clad in copper, with smaller copper elements framing the windows. A column-free floor plan allows each floor to consist of one large space, arranged like a ring around the central core. Oak clads the core walls and the floors.
