DEVELOPERS are 'passionate' about enhancing the historical value of a former US airbase in a village near Bicester, but there are concerns that character of the site may be lost. Dorchester Living will convert the Cold War base in Upper Heyford, demolishing a hangar, bomb stores and hardened squadron HQ in the process. It will have 1,175 homes, a primary school, social facilities and filming site dubbed a 'creative city'. Developers want to 'reinvigorate' the area while preserving the sites heritage, but there are some concerns that too much of the site will be destroyed, losing its character. Bicester Local History Society member Matthew Hathaway who lives in Heyford Park, next to where the next phase of development will take place, said: "As I live on the site I do see the development going up around me and realise that the building I'm in is one of the ever dwindling list of old buildings they are keeping.
