Plans for 1,000 new homes would double the size of a village and would be a “carbuncle” on the landscape, campaigners say.
Hardingstone residents are calling for support in their fight against the homes, which would be built on land behind The Warren and Newport Pagnell Road.
An application was submitted to Northampton Borough Council by the Government-backed Homes and Communities Agency in March, which Hardingstone Parish Council has formally objected to.
And the council is lending its support to the fledgling Hardingstone Action Group, which is currently meeting every fortnight, and is on the lookout for more members.
Hardingstone currently has about 950 homes and 1,600 residents.
Gordon Crowe, who set up the action group, said: “We are putting in our objections based on the complete lack of infrastructure. The Highways Agency is saying there is nothing they can do to enhance the roads, and the village is already suffering from rat-running.
“We will move on to concerns about the environmental impact, and the third element of building houses but not building any schools.
“It is going to be a carbuncle on the side of Hardingstone.”
Gillian Greaves, chair of the parish council, said: “The whole area is over-developed and Newport Pagnell Road does not provide the infrastructure.”
The action group meets fortnightly on Wednesdays in the Parish Room, at 7.30pm. The next meeting is on August 28. For details visit www.savehardingstone.wordpress.com
