Campaigners have handed in new proposals to revive the ailing King Alfred sports centre on Hove seafront.
Pressure group The People's Proposal had submitted ambitious plans to rebuild the King Alfred.
But they were rejected as being impractical by Brighton and Hove City Council, which owns the pre-war building.
The council is now expected to go ahead with its own scheme for rebuilding the centre, funded by up to 400 flats on part of the site off Kingsway.
It says survey results show 80 per cent of people are in favour.
But the People's Proposal strongly opposes housing and has put in new plans to renovate the centre.
They want councillors to consider the alternative before making a decision at a policy committee meeting tomorrow.
Spokeswoman Jan Young, of Court Farm Road in Hove, said: "The alternative People's Proposal is to refurbish the King Alfred to a high standard but still incorporate commercial aspects.
"This would cost about £5 million. With National Lottery and other funding, the shortfall should be met by the council.
"The council would then have a magnificent leisure centre and still own the land."
Hundreds of people are expected to sign forms saying they favour the new proposals.
Under the plans there would be a main swimming pool with an outdoors pool that would be converted into a skating rink in the winter.
There would also be a wave pool, a sun deck area, a roller skating area and a cyber cafe.
Also in the plans are facilities for ten-pin bowling, a health and fitness centre, a hall for racquet sports, a gym, five-a-side football pitches and netball and volleyball courts.
Liberal Democrat group leader Paul Elgood will voice his concern about the council's plans at tomorrow's meeting.
He said: "A more measured redevelopment would not require such a large number of flats but still achieve much of what is proposed."
