EACH of the three often damp blocks seem to sum up the "challenges" facing GHA.

The 23-storey Dundasvale flats in Glasgow's Cowcaddens are far from the worst in the city. Popular and centrally located, the homes are expected to have a future far longer than some of Glasgow's slum skyscrapers. But they are to stay up at a cost.

GHA yesterday confirmed all the windows in 719 Dundasvale properties, including 412 flats in the multis, would have to be replaced - for the third time since 2002.

Water has been getting in through the new windows or their frames, causing damage. Columns supporting the buildings are crumbling. So are parts of a car park in the development. Nothing dangerous, nothing permanent - but new windows will cost more than £1.6m and more than another £2m is needed to fix water damage.

Tenants face months of inconvenience. The more than 60 owner-occupiers would normally be facing big bills. They won't: GHA has to have all their windows replaced to get a warranty for a £3m overcladding project also proposed for the buildings.

For several years GHA and housing associations across Glasgow have been haggling over the price they will pay for stock during second-stage transfer, the break-up of the giant landlord. GHA keeps changing valuations, buyers complain. "How much would you pay for the Dundasvale flats?" one association official asked. As renovation reveals increasing problems with the stock GHA inherited from the council, that question becomes more and more pertinent.
