The support comes as the council starts legal action to try to end the occupation.

Royal Park Primary School in Woodhouse has stood empty since its closure five years ago while the council considers options for its future.

But concerned at the Victorian building's rapidly deteriorating condition and lack of progress, a group of residents who want it saving for community use last week gained access and set about repairing it themselves.

They argue that the council has failed to properly maintain the building and fear it could be demolished unless the disrepair is tackled urgently.

And their direct action has been praised by Rita Samuel, who taught at the school for 16 years and was headteacher when it closed in 2004.

Over the weekend she was given a tour of her former workplace by volunteers carrying out the work. Ms Samuel was dismayed at what she saw.

She said the rooms were dilapidated, sinks had been ripped out and rainwater had ruined flooring put in not long before the school closed.

Ms Samuel said: "It was just so sad to see it in such a state because it was well maintained when it was open.

"But it was heartening to see that some people had taken a stand and were making it clear to the council just how much the community valued the building.

"They are doing a wonderful job and have already made a significant difference.

"We had a reunion on Friday of former staff and everyone was so pleased something was happening because they have had to watch it go to wrack and ruin.

"When the school closed it was done so on the promise it would be retained for community use but that has not happened.

"It is ideal for community use. It has two large halls and lots of other rooms which were used seven days a week by the community when the school was opened."

Having cleared the building of rubbish and debris, those occupying it have already set about introducing some community uses.

Over the weekend the former school hosted a jumble sale and circus skills activities for children.

The council has said it is in the process of inviting best and final bids for the building from prospective developers.

A council spokesman said: "A full risk assessment has been carried out and the residents who are staying inside the building have been made aware of our concerns for their safety.

"We have met with the group to discuss their position but have no choice but to begin legal proceedings to have them removed."
