The Chalet Restoration Action Group (CRAG) has asked the architect to design a 'means of re-use' for the remains of one of Europe's largest lidos.
Local residents have compiled a petition, submitted to the local authority at St Leonards, Hastings, to save and re-use the two-storey block of chalets, which has been boarded up ahead of its planned demolition.
SAVE Britain's Heritage secretary Adam Wilkinson said: 'SAVE has been extremely concerned about these buildings since we first learned about the threat of demolition in 2001.
'Their demolition would be completely unnecessary, and we hold serious reservations about the local authority's approach to this site.'
Architect and concrete enthusiast Sidney Little designed the chalets, also known as the Sydney Bathing Station, in 1933 for the Empire Games in 1934.
The Twentieth Century Society has joined in with the call to save the buildings, having urged the local council to rethink the future of the building.
