Plans for a 21,500 capacity entertainment venue in Stratford, east London have been published by American venues operator Madison Square Garden Company (MSG).
MSG plans to build the spherical structure housing the venue close to the former Olympic park in Stratford.
According to planning application documents, the proposed development will be 120m in diameter, and will be 90m high, covering 2.98ha.
The sphere will sit on a four-storey base. Its exterior will be clad with triangular LED panels displaying moving images.
The developer plans to build three new pedestrian bridges to provide spectator access to the 20-storey.
A fourth bridge will give service vehicles access to the site.
The sphere will have a geodesic steel frame tied to floor slabs for stability and resting on 21m deep piles.
Three layers will make up the sphere’s envelope, according to the planning documents – structural, acoustic and façade.
The structural layer of the sphere will include primary and secondary steel members, while the acoustic layer will consist of a steel deck and insulation.
Meanwhile, the outer layer will consist of standing seam metal panels, panel support rail and LED panels.
Stainless steel has been selected as the facade material for durability and corrosion resistance.
Populous is the lead consultant and architect for the project.
Developers hope to start construction this summer with work taking three years.
