THE battle to save an historic mansion is gathering pace once again after English Heritage said it will not support the council's decision to have it demolished.
Derelict Dollis Hill House, a Grade II listed regency villa in Gladstone Park, is planned to be knocked down.
Brent Council believes it has exhausted all avenues to try and save the house and applied to the Government Office for London earlier this year to have it torn down.
But in a letter sent to the council from English Heritage last week, it claims statutory requirements have not been met and said the council needs to go back to the drawing board to find an alternative solution.
Gill Close, chairwoman of the Dollis Hill House Trust, said: "We are relieved that all our hard work to show that there are more creative ways to save Dollis Hill House for the community has contributed to this positive outcome.
"We are very excited about English Heritage's offer to work with the council to find a solution.
"In this fantastic location in a beautiful park overlooking London we can find a way to celebrate the house's heritage and bring the community together."
The mansion housed guests such as the 19th century prime minister William Gladstone and American author Mark Twain.
Plans to transform the mansion into a tea-room and restaurant were scrapped and the campaign to save the building took another blow when Mayor of London, Boris Johnson, announced he would not pledge any money to its proposed generation.
The former mayor, Ken Livingstone, had promised to part-fund the restoration of the 200-year-old building.
But the council's executive committee agreed last December to apply for permission to have it demolished.
English Heritage recommends the council considers another feasibility study or marketing campaign on a wider basis than was carried out before.
A spokesman for the council said: "We can confirm that we have received a letter from English Heritage objecting to the planning application for listed building consent to demolish Dollis Hill House.
"Brent Council planning officers will consider the objections before putting a recommendation to a future meeting of the council's planning committee."
