Opposite Jing An Park and between Nanjing Xi Lu and Yan’An Xi Lu, lies the 66 storey Wheelock Square, which both anchors the western end of Nanjing Xi Lu, and acts as a major landmark along the elevated highway connecting downtown Shanghai with the west.

The tower visualizes a simple, singular, sculptural form, rising from a richly landscaped plaza. Its glass curtain wall extends to the top as a series of planes that rise as they move away from the sculpted corner, resulting in a dynamic form derived from a very simple plan.
The base of the tower forms both a canopy and terrace for those approaching the lobby. The tower sits on a square, stone base, raised several steps from the surrounding plaza. A 2,000-square-meter retail element sits at the southwest corner of the site, connected to the tower by a covered walkway. This forms an intimate space for outdoor dining between its own mass and the tower lobby.

ALT proposed the application of a unitized curtain wall system and the adaptation of an open-joint system. The glass wall uses low-E coated and insulated vision glass units, which are structurally-glazed on the vertical sides and aluminum-capped on the horizontal sides. These contain tubular fins that project out 250mm throughout the entire face of the tower.
The tower façade is a combination of both flat and slightly-sloping glass walls, bounded at each of its square corners by large metal steel framed architectural features. The aluminum-cladded corner features, cantilevered off the tower main structure, are supported by protruding steel struts, and are accentuated vertically by continuous surface-mounted lighting.

ALT considers the lantern at the tower crown as one of the façade design challenges. It adopts a unitized glass curtain wall similar to the typical tower, but is steel-supported with an inner aluminum skin incorporated at the interior side to conceal mechanical and building maintenance unit equipments. It forms a light box that illuminates the skylight at night.
