The All England Club is set to build 39 new tennis courts at Wimbledon as the site expands into neighbouring parkland.
Plans include an 8,000-seater show court with a retractable roof, which will make it the third biggest court at the tournament behind Centre and Court One.
Officials said it will be set within a ring of ancient oak trees and be ready to host matches from 2030.
The 38 other courts in the expansion will have temporary seating in a bid to reduce the site's impact on the park, originally designed by Capability Brown in the 18th century.
Wimbledon's £65 million bid to acquire the land from Wimbledon Park Golf Club was accepted in 2018.
The club anticipates submitting a planning application in July, with work beginning as early as January 2022.
Central to the plans – released as part of a second consultation document – is a restoration of areas of the land in keeping with Brown’s vision.
The serpentine lake will be restored and a further 1,000 trees planted, including historic species.
Capacity will only be increased from 42,000 to 50,000 spectators per day, which should make the grounds significantly less crowded, while Church Road – which bisects the two halves of the site – will be closed during the championships, partly for security reasons.
A chief motivation for acquiring the parkland was to enable qualifying for the tournament to be held on-site.
It is currently played at nearby Roehampton, but the plan is for it to be moved by 2028.
A new energy centre located in the park, meanwhile, will play a key role in Wimbledon’s plans to be carbon neutral by 2030.
The 2021 championships are set to begin on Monday 28 June.
