28/02/13 ..Trentham Hall in the spring sunshine today. A grade-II listed building may be left to decay after redevelopment costs came in at an estimated £35 million..The 180-year-old Trentham Hall, in Trentham Gardens, near Stoke on Trent, Staffordshire, has once again been named on English Heritage's 'at risk' register...Planning permission for the landmark building, which is owned by St Modwen, has been granted to redevelop the site as a conference hotel. But St Modwen says the cost of repair is too high...It means the building will have to remain in its current state. Mike Herbert, North Staffordshire regional director at St Modwen, said: "We have planning approvals for the restoration of Trentham Hall but the cost of doing so is significantly greater than its current value..."To restore and rebuild it would cost around £30-£35million, but the current value as a hotel is well below that. Therefore, it is just not economically viable in the current economy...Dr Simon Thurley, chief executive of English Heritage, said: "Grade II-listed buildings are the bulk of the nation's heritage treasury. So when one of them is lost, it is as though someone has rubbed out a bit of the past. Something that made the area special will have gone. But now, with the economic climate putting more pressure than ever on these buildings, it is time to plug the one remaining gap."...All Rights Reserved - F Stop Press. www.fstoppress.com.
