New images have been released to showcase how a “world-renowned venue” could look after a £45m revamp.
As part of the plans, The Crucible Theatre in Sheffield, which has hosted the World Snooker Championship since 1977, is set to increase capacity from 964 seats to 1,500, Sheffield City Council said.
Pictures show the proposed look for its in-the-round stage, a redesigned entrance and a balcony overlooking Tudor Square.
Council leader Fran Belbin said: “These new images bring the vision for its future to life showing how we can preserve both its unique atmosphere and its legacy while creating a modern, sustainable venue fit for generations to come.”
The Crucible refurbishment is a key part of a deal agreed between the council, the venue and World Snooker Ltd to secure the future of the tournament in Sheffield for at least 15 years and up to 20 years after the redevelopment.
World Snooker wanted increased audience capacity and improved visitor and behind-the-scenes facilities to stay.
The deal was brokered following the intervention of outgoing Prime Minister Sir Keir Starmer during a visit to The Crucible in March.
