A former tuberculosis hospital and drug treatment centre is up for sale for the second time in nine months - this time with a �1.3m price tag.

The Diana Princess of Wales centre in the old Mundesley Hospital closed last summer after 12 years helping drug and alcohol addicts.

Owners Adapt hit financial problems early in 2009 and, after administrators failed to find a buyer to take it on as an operational clinic, patients were relocated and the 19-acre site was put on the open market. The estate, which includes Grade II listed hospital buildings and woodland, was bought for a price in excess of �750,000 in November by homeopathic practitioner Eveline Herzer.

It is not clear why the property is up for sale again so soon, although Tom Goodley, from agents Strutt and Parker, said: 'Our client has decided it is not exactly what they were looking for. I think their business plan has had a change of tack.'

He said there had already been a couple of viewings of the site within just three days of it going on the market. He added: 'This amount of land and property doesn't come up very often - 45,000 sq ft in 19 acres in north Norfolk, next to the coast and a mile from the beach, is rare.'

When the site was bought late last year few details about its future were ever revealed although, in a letter to neighbour Sarah Morgan, Mrs Herzer's solicitor said it would be used for 'respite care for those suffering from terminal illness as well as a place of spiritual retreat'.

Mrs Morgan, who has lived next door in The Old Night Nurses Home since 1995, said there had never been any sign of the Victorian buildings being redeveloped for the new centre.

She said: 'I would know because they pretty much have to drive past my house if there is going to be any work vans. They've kept the grounds beautifully, they've mown and trimmed the hedges, but as far as I can see they haven't done any internal work or building work.'

While the site cannot be turned into homes, it is thought it could have a number of other uses in the future.
