Harefield Grove, Hillingdon

Only one London street atlas identifies this as a discrete locality, situated north of Harefield proper on Rickmansworth Road and consisting of little more than one farm and one mansion

Harefield Grove Farm

There has been a farm here since at least 1684, when it was called Guttersdean Farm. It is now Harefield Grove Farm. In the late 19th century exotic fruits and vegetables were grown for the London market in over 100 green­houses with 50 miles of hot water piping.

Harefield Grove is a grade II listed house, probably of 18th-​​century origin but signi­ficantly altered on a least two subsequent occasions. It is most notable for its grounds, with lakes and a waterfall, which are among the few surviving landscaped gardens in London not to have been opened to the public. The house was restored and converted to offices in 1985.

A small studio was constructed at Harefield Grove Farm to create CI5’s headquarters in the first season of The Profes­sionals, a 1970s crime-​​action drama. Some exterior scenes were shot at locations nearby.
