A Cropredy action group says a plan to build a 67-home development on fields in the village is overwhelmingly opposed by villagers.
Members of Croppers (Cropredy Residents Opposing Planning Permission on Exquisite Rural Sites) have conducted a 276-home, house to house survey of every property in the village.
And they say more than 91 per cent have registered their opposition to the proposals by David Wilson Homes.
The land, behind houses along Station Road, is owned by Brasenose College, Oxford.
Croppers spokesman Jesse Crosse said: “The proposed development is unsustainable.
“The local plan allows for Cropredy to grow at the rate of one house every two years, or ten houses between now and 2031. The spirit of the Battle of Cropredy Bridge in 1644 lives on and we’re quite prepared for a battle of a different sort to preserve the character of this historic village.”
Richard Skeates of property consultancy Bidwells said: “Brasenose has held land in its endowment fund which is managed to produce income to support college activities.
“This includes land at Cropredy which has accommodated sustainable development since 1519. Brasenose is currently in discussions to sell land for development which is appropriate to the village and accords with Cherwell District Council’s planning strategy.”
