Osterley House

Osterley House is an 18th-century mansion in Isleworth in the London Borough of Hounslow. The main building in neoclassical style stands amid broad lawns and landscaped ponds that together form a generous ensemble.

In the 16th century, banker Thomas Gresham had a manor house built here. Between 1761 and 1765, the architect Robert Adam completely redesigned the building for the wealthy Child family.

The estate name refers to the old parish of Osterley, already recorded in medieval church registers. Visitors can walk through the rooms and see the furniture and wall coverings that the architect designed for the Child family and that remain original today.

Osterley Underground station is nearby and offers direct access to the estate. On the grounds, paved paths run through the park, and a cafe in the former stable buildings provides a place to rest.

During the Second World War, Home Guard volunteers used the grounds for their first drills to defend the British coast. These units trained tactics here that were later applied across the country.
