Design

Overview

The facades of the complex are connected with diagonal folds and are linked by a faceted base, giving a noticeable shard effect that defines the towers' appearance. In addition, the towers' canted folds allow each other to recede from one another as they rise. The complex forms an L-shaped composition at the ground plane that is pulled to perimeter of the site. This placement and the facade folds both allow the building to lean over the nearby Third Ring Road. A landscaped plaza sits at the base of the buildings and creates a sheltered, private garden that guides occupants to separate lobbies, in addition to give public space to pedestrians to rest. The building’s all-glass facade offers several features that benefit its occupants. Ventilated mullions can be opened manually to allow natural air flow into the interior. These mullions also help to mitigate stack effect. These features also allow the complex to give out a dynamic and shifting exterior. In addition, the 28th and 49th floors of the North Tower and the 7th, 27th, 46th, 65th and 83rd floors of the South Tower have
