 原文内容London-based PLP Architecture has revealed a master plan for a project in China that includes a concept for a supertall tower composed of three rotated, interlocking volumes. Proposed for a site in Shenzhen, PLP's proposal features two towers, a performing arts complex, and a series of connecting structures and bridges that will accommodate retail and entertainment spaces.
The centerpiece will be the 124-story, 595-meter-tall Nexus Tower, which will consist of three rectilinear volumes of varying heights, slotted together to "form a propeller-like configuration," the firm said.
"The starting point for the Nexus building is the search for an alternative to the high-rise point tower typology, where a large central core is surrounded by usable space," said David Leventhal, a partner at PLP.
In the standard central-core tower, interior spaces often lack flexibility, views, and vertical movement, said the firm. Instead of one structure, PLP's building is conceived as three separate towers connected by a central supporting structure, like propellers around an axle, providing uninterrupted floor space.
"The usable space of each component is liberated to the outside, in a centrifugal manner," the firm said.
The structural system will still have a central vertical core, and this will be supported laterally by three perimeter cores joined via trusses on designated mechanical, electrical, and plumbing (MEP) service floors. Core walls and columns will act together to transmit the building's gravity load to the foundation, the firm said.
The Nexus Tower will mostly contain offices, although it will have an eight-story retail podium at its base and a 14-story hotel at the top. Shuttle elevators will operate on a pre-determined schedule rather than on demand, and will terminate at transfer levels at the top of the two lowest volumes. From these levels, vertical circulation will be moved to the perimeter of the building, where double-decker lifts will offer panoramic views of the city and act as "mobile observation decks."
"For the people working inside, every journey through the building will contain at least one possibility of sensing the astonishing height of the tower in a direct, visceral way," said Andrei Martin, a partner at PLP. "Similarly, from the outside, the cantilevered volumes produce a slightly unstable reading that hints at a defiance of gravity."
The firm's master plan also includes a 347-meter office tower that features a pair of interlocking volumes. "Whilst the lower volume is angled in order to reveal more of the nearby tower and views from the park, the upper volume forms a cantilever that appears to look towards the middle of the site," said the firm.
Another part of the development is PLP's Platform for Contemporary Arts building, which will consist of a music hall, multipurpose space, cinema, and a 1,700-seat theater. This will sit atop an elevated platform that is supported by three giant columns. The platform's structure will consist of a concrete frame and steel trusses.
The scheme also features several bridges that will connect different areas of the development. The passageways, collectively referred to as The Concourse, will feature spaces for retail and entertainment.
The first part of the project is expected to be finished by 2020. PLP did not disclose the name of the client for the proposal. |
