Persimmon Homes plan for 400 properties in formerGrove Airfield PLANS for hundreds of homes in an Oxfordshire village have sparked concerns about contamination. Persimmon Homes – the developer behind the 2,500-home Wellington Gate estate at Grove Airfield – has now applied for planning permission to build more than 400 extra homes on the northern edge of the new estate – which is still under construction. The plan also includes new access roads, open space, landscaping and drainage. The land is already earmarked for 400 homes in Vale of White Horse District Council s Local Plan – and it is to that council that Persimmon has submitted its application, saying the site could take ‘considerably more’ housing.
