Not visible from the Longcross Road, Barrow Hills is a Grade II listed manor house within the perimeter fencing of the Longcross Test Track. Heck, I’ve passed by often enough when working in Chertsey, and never knew it was there.
Now however, with the Longcross South housing development, there are images of the manor house on the Longcross Village website HERE. There are many more images on the Longcross Studios website, where the manor house is used as a film location.
I’ve combined the images from the variety of sources in this brief photo montage.
