The Brighton architect Nick Lomax has given glimpses of his alternative vision for the King Alfred site on Hove seafront.
Mr Lomax’s practice, LCE, was the lead architect for the Bouygues bid to build a new leisure centre and hundreds of homes.
Bouygues lost out to the housebuilder Crest Nicholson and the Starr Trust, a charity led by local businessman Rob Starr.
The Crest Nicholson proposal was picked by Brighton and Hove City Council – the landowner – at a meeting in January.
LCE said: “The design of the leisure centre responds strongly to the visual prominence and exposure of the site.
“The pool hall was designed to be highly visible externally from a distance, particularly from the west and south.”
