Andrew Billingham, Chief Executive of YTL Arena, said: “We want to attract the biggest artists and events to Bristol, so increasing the capacity to 20,000 is really important to us.
“We’ll achieved this by maximising the size of the floor of what will be our standing area, where concertgoers will be stood on the very same concrete where Concorde was built.”
The Filton arena was promoted as a more affordable alternative to a previously council-backed scheme next to Bristol Temple Meads railway station.
That was first proposed in 2003, but building work never started, and while the plan was resurrected in the 2010s, former city mayor Marvin Rees scrapped the plan.
While construction is yet to begin on the Filton arena, work on a railway station to bring concert-goers to the venue is under way.
The brand new station, North Filton, is set open as an unstaffed station in late 2026, though this is set to be enlarged later when the arena nears completion.
Elsewhere, hundreds of people have already bought and moved into new homes as part of the development, and there are plans for schools, student accommodation and sports facilities.
