Wash Common is a suburban village to the south of Newbury. It is built on the former Newbury Wash, which was flat open heathland overlooking Newbury, and until the 19th century there was just a small group of houses separated from Newbury by open country. Both places have grown into each other, and the suburb of Wash Common is now contiguous with Newbury. Most housing development has taken place to the west of the Andover road, and some of the area to the east of the road still remains open farmland.
