400 homes could be built in Bishops Green Land company wants Basingstoke and Deane to allocate site for housing Jonathan Ashby '); THE south side of Newbury could undergo a huge transformation after land in Bishops Green in Basingstoke and Deane was targeted for a 400-home development. In October this year, Catesby Estates entered into an agreement with the owner of Bishops Green Farm, off Ecchinswell Road, opposite Ash and Eagle Road estates and just a stone’s throw from the West Berkshire border, to promote the land. This means that Catesby Estates will try to get planning permission for a development and then market the site to housebuilders.
