Ossulston House

Ossulston House is a Grade II listed building in Hadley Green Road, Hadley, to the north of Chipping Barnet. It is one of an almost complete line of houses that once stood between Chipping Barnet and Monken Hadley along the east side of Hadley Common which were built in the 18th and 19th centuries as wealthy merchants from London populated the area.

The house was built soon after 1764 by sugar refiner John Horton on the site of the Rose and Crown inn and acquired in 1786 by William Makepeace Thackeray, grandfather of the novelist of the same name. It was once owned by the Earl of Tankerville.
