Belsize fire station has already attracted a “great deal of interest” from developers after been put up for sale just months after Mayor of London Boris Johnson forced its closure.

The Grade II-listed station ended 99 years of service on January 9 after Mr Johnson defeated a High Court challenge from Camden Council and other London boroughs against his £29million fire service cuts plan.

The station in Lancaster Grove, Belsize Park, has now gone on the property market with Dron & Wright, which said there has already been plenty of interest “as you can imagine”.

Belsize Park estate agent Jon Rose, of Heywoods Estate Agents, said the 16,600 sq ft building could be worth more than £20million at resale, after being converted into housing, based on the high value of property in the area.

He added: “Very few reasonable sized development possibilities come up in Belsize Park. There are a lot of developers around and this is prime Belsize Park property.”

The news may come as a blow to Abacus Belsize Primary School, the new free school in Belsize Park which opened in September and is hunting for a permanent home. It had earmarked the fire station as a possible home.
