A fire ripped through a site office at a development in Carshalton last night.

London Fire brigade received the first calls at about 7.50pm Friday night of a blaze in Durand Close, Carshalton.

The street is an old 1950s council estate that is currently being redeveloped.

Crews from Sutton and Wallington were first on the scene and reported smoke punching through the front of the building and flames out of the rear of the building, an old shop that was being used as a site office.

Above the site office was two derelict flats and the fire had spread vertically to these as well.

The flats were securely locked to prevent anyone entering the derelict building, adding to the fire fighters’ difficulties in accessing the property to put out the fire.

Crews from Mitcham, Norbury, Wandsworth, West Norwood and Wimbledon also attended with rescue units and aerial ladders to help control the large blaze.

The fire was finally put out at about 1am.

There was nobody in the site office, which was completely destroyed.

Fire investigation teams and the police are investigating the cause of the fire.
