My daughter worked there for a while quite recently and said it was in very poor condition with certain areas that were a bit dangerous and that they were not allowed to go there for safety reasons.
I think the cost of bringing it back would have been prohibitive.
We've seen other examples of buildings that were old and in bad condition that no one would buy because of the costs involved - with the new owners under the cosh of the planning rules and regulations.
I remember a building on Sheffield Road that was once owned by Stylax & Paradise (sp) opposite the old Grammar School. A friend wanted to buy it but couldn't afford all the costs laid down by the preservation folks. It just rotted away until it had to be pulled down.
Tricky situations...
