English Heritage will decide if the Grade II listed building that has stood in Gladstone Park for more than 200 years can be removed.
Plans to renvoate the building fell apart when Boris Johnson eclined to honour predecessor Ken Livingstone's oledge to fund the rebuild. See previous lookwest coverage for details.
Martin Redstone, from the Dollis Hill House Trust (DHHT) told the Harrow Observer he was disappointed with the decision, unanimously made at a council executive meeting last night, but accepted the local authority had no other choice.
"We were very buoyant last year after getting TFL on board and securing the funding, but we have basically been credit crunched," he said.
"The process of getting consent from English Heritage will take about a year so we are still hopeful that another group will show some interest in taking the project on but money is tight everywhere."
The council plan to simply demolish the building and landscape the site.
