The All England Club will build 39 new tennis courts at Wimbledon, while the grounds will expand into the neighboring parkland.
A show area with 8,000 seats and a retractable roof is planned, which will be the third largest area of the tournament after Center and Court One.
Officials said it will stand in a ring made of old oak trees and be ready to host games from 2030 onwards.
The 38 other courts in the extension will have temporary seating to reduce the site’s impact on the park, which was originally designed by Capability Brown in the 18th century.
Wimbledon’s £ 65 million offer to purchase the property from Wimbledon Park Golf Club was accepted in 2018.
The club expects to submit a planning proposal in July. Work will start as early as January 2022.
At the heart of the plans – published as part of a second consultation document – is the restoration of land in line with Brown’s vision.
The Serpentine Lake is being restored and another 1,000 trees are being planted, including historical species.
Capacity will only be increased from 42,000 to 50,000 spectators per day, which should make the site significantly less crowded, while Church Road – which bisects the two halves of the site – will be closed during the championships, partly for safety reasons.
A main motivation for purchasing the parkland was to enable qualification for the tournament on site.
It is currently being played in nearby Roehampton but is slated to be postponed until 2028.
A new energy center in the park, meanwhile, will play a key role in Wimbledon’s plans to be carbon neutral by 2030.
The 2021 championships start on Monday June 28th.
