The West Park development on the western edge of Darlington is a successful housing project with a sophisticated landscape concept that is integral to the site’s identity and value. A section of land adjacent to the West Park village centre contains a major water pipe that crosses from West to East. The constraints on use, preclude the corridor being developed, but allow the land to be part of the green space pattern of the site providing landfrom changes that are less than plus or minus 300mm.
