Land in Kenilworth and Burton Green could be used as part of plans to build thousands of new homes in Warwick district.
Sites at Hurst Farm and east of Glasshouse Lane are among six areas, which emerged last week as possible locations for hundreds of houses.
Warwick District Council has been told by the government to find land for 11,000 new homes by 2026 and has a
lready carried out public consultations for other areas as part of its Core Strategy Preferred Options document.
Cllr Michael Coker (Lib Dem, Kenilworth Abbey) said: "As far as we are concerned this is not on at all.
"Development at Burton Green was considered originally by the district and it was not proceeded with and that was correct.
"It has already been agreed that Warwick University will be extending into the greenbelt in that area over the next five or six years.
"This will be on the edge of that and eventually we shall be joined with Coventry.
"They don't want it and we don't want it - it is taking away the little bit of greenbelt that is left and that is completely inappropriate."
Glasshouse Lane has already been earmarked as a possible site for 750 houses and the new plans would add to that number while replacing Kenilworth Wardens Cricket Club and the Woodside Training Centre.
With proposals also being considered to build and extra 3,500 homes in the Kings Hill area of Stoneleigh, Cllr Coker is concerned the total number of houses in Warwick district will cover an area larger than Kenilworth.
He said: "What it comes down to is the government is asking us to do it.
"The whole thing is farcical and will destroy the character of the district.
"It is very worrying."
Cllr Coker is urging people to respond to consultations, which begin at the end of the month and will run for six weeks.
Cllr Michael Doody (Con, Radford Semele), the district council's leader, said those living near the six sites have less cause for concern than people whose areas have already undergone consultations.
He added: "They have always been about but we have decided they are not feasible in most cases and because of that they were put to one side.
"This is about safeguarding the council against the embarrassment of an inspector saying we have overlooked these areas."
