The Changjiang office building and hotel take the form of a single slender 220m tower high on a prominent site in central Nanjing.
The tower is shaped and tapering in response to the optimum floor plates size for each of the office and hotel functional components.
In response to the site and setback shape the tower is generally rectangular along its east-west axis, then tapers to square at its upper
levels as the core reduces in size. The shaping of the building form establishes an emphatic address to Changjiang Road as well as a dramatic
profile seen from Zhongshan Road.
Retail activities and the hotel lobby are located at a lower ground (B1) level which is opened up to a series
of stepped and lower level gardens. The hotel is located on the lower tower floor levels with recreational and facilities positioned at the vertical
junction with the office floors above.
The facade treatment of closely spaced tapering vertical mullions creates the basis for an integrated shading system
emphasizing both the building?s height and form. The pattern is disrupted by a series of vertical occlusions which open the facade for building entries
and drop-offs as well as vertical sky-gardens on the upper hotel and office floors.
