More than 2,500 people have joined a campaign to save the historic Saltdean Lido from closure.
The 1930s outdoor swimming pool’s owner, Dennis Audley, wants to concrete over the pool and build 100 flats in a £12million development. The building’s facade would stay intact, and a library would be built.
Mr Audley told The Argus he had lost £250,000 running the lido over the past ten years, which he blamed in part on the weather.
But the outcry over his plans suggests there is still a huge amount of local support for the pool.
A taskforce has also been set up via a Facebook Group, which is contacting English Heritage to try and upgrade its listing from Grade II to Grade II*.
The group has also dug out the details of its existing listing, which shows not just the facade but the whole pool, including its interior, is protected from development.
It is also in talks with Fusion, which has turned around another Art Deco outdoor pool, the Brockwell Lido, known as Brixton’s Beach.
The pool is owned by Brighton and Hove City Council, and the 99-year lease passed to Mr Audley in the early 2000s.
