Osterley is on elevated soil,[2] bisected by the A4 (Great West Road), and extends north of the M4 motorway. Syon Lane forms the border to the east, while the border with Heston is to the west. Osterley extends south of the A4, including St Mary's Church.
Most of the land of Osterley is the large ancestral private estate of Osterley Park (one of the largest open spaces in west London) and its mansion. These were formerly owned by the Jersey family and were used during World War II as the home for Tom Wintringham's Home Guard training school. They are now National Trust property. In the 1930s, when the Great West Road was completed, ribbon development housing appeared, and this gradually expanded to form the comparatively small residential sections within Osterley.
Besides Osterley House and Park, the district is also known for one of the London residences of The Sultan of Brunei (Aviary Farm in Windmill Lane).
