However, Arthur Andersen, receiver for the land's liquidated owner Alfred Walker, looks set to push ahead with the half-residential, half-commercial scheme.
It is understood that Andersen is in talks to sell the land to a number of potential buyers, including Locking Castle, a consortium of housebuilders made up of Westbury, Persimmon and Barratt. The consortium owns a neighbouring 200 ha housing development.
Clive Wiltshire, Westbury's regional managing director, declined to comment, describing any such negotiations as commercially sensitive. But he did add: "I understand many of the majors are interested."
Andersen believes that planning permission will bump up the site's sale value – it is believed that the receiver is asking for £20m.
Elfan Ap Rees, who chaired the planning committee until May this year, said a planning application for the proposed 2190 new homes would face serious difficulties, but confirmed that Andersen was proposing to put in an application.
He said: "The plans are not in line with the structure plan or local plan – the airfield is allocated for employment purposes."
The commercial element, which covers half the site, includes a hotel and shopping facilities.
Another problem facing developers is that parts of the airfield are open spaces, and as such may be classed as greenfield land.
Ap Rees criticised the receiver for seeking to sell the land in a single block.
Andersen was unavailable for comment about the site.
