Much needed repairs costing about £500,000 are planned at Bury St Edmunds Leisure Centre.
St Edmundsbury Borough Council, which owns the facility, wants to replace existing cladding and flumes as well as build a draught lobby to the building’s main entrance.
The authority says the replacements are needed as the features have started to deteriorate and the work would improve energy efficiency.
A spokeswoman said: “We are awaiting confirmation of costs but the project will be in the region of £500,000 if it all goes ahead.” She added that work ‘will be managed to cause the minimum of disruption to users’ and the outside appearance of the building ‘won’t be materially altered’.
A decision is due to be made on Thursday by the council’s development control committee.
