A newly refurbished bandstand costing hundreds of thousands of pounds is already showing signs of decline - just a month after it was reopened.

The £850,000 restoration of Brighton’s birdcage bandstand was paid for by Brighton and Hove City Council.

But promenaders have told The Argus signs of rust are already emerging on the 125-year-old structure.

Alan Thorpe, of Roseberry Avenue, Brighton, said: “In one of her weekly articles Councillor Mary Mears wrote that the restoration gave us sense of civic pride.

“I cannot see what pride she can take in it."

The structure, near the West Pier, had been derelict for 35 years.

Despite a 10 month refurbishment, rust spots on the green supporting columns were identified on the opening evening.

Further rust stains have since appeared on white decorative ironwork.

Patricia Horne, of Friends of Brighton Bandstand, who campaigned for its reopening, said: “It is quite to sad to see but it’s because the bandstand was left to rot for so long.

“Work will need to be carried out on it every year but I think we should concentrate on the positives.

“It’s fantastic it is back open and I want to thank everyone who signed the petition to reopen it.”

Councillor Geoffrey Theobald, the council’s cabinet member for environment, said: “Any major building project will throw up some ‘snagging’ items after completion.

“Work to rectify any issues, such as rust spots, is all part of the contract and will be done at no extra cost.

“The contractor will be undertaking the work after the final programmed band performance on September 6 so that everyone has a chance to enjoy the bandstand for the remainder of the summer.”

Steve Hayman, of constructors Cheesmur confirmed they would carry out repairs as part of their 12 month warranty contract.

Mr Hayman said: “Because of its shape and seafront location there are areas which will need constant work.”

A spokesman for the council added once the job had been signed off, a budget, aided by the bandstand’s own income, will pay for its annual upkeep.
