British architecture studio Foster + Partners has completed DJI Sky City, connected by an open-air 90-meter-long suspension bridge over 100 meters above the ground. The bridge is attached to each of the towers' vertically cores, which both support a series of steel truss-encased, glass volumes that were stacked and cantilevered on top of one another at varying heights. The cantilevered blocks contain column-free office spaces that were made possible by the building's external truss systems. Some of the column-free interior spaces contain four-story high dedicated drone flight testing labs.
DJI Sky City consists of a pair of 200-meter-high skyscrapers that house the headquarters and innovation center of Shenzhen-based robotics company and drone specialists DJI. The ground floor houses the building's public facilities, including a community healthcare center, as well as its lobbies each contain an indoor "zen" garden that extends from a rammed earth feature wall. At the top of the buildings, each of the cantilevered volumes has rooftop gardens with views across Shenzhen as outdoor spaces for DJI employees.
