Irchester campaigners met Wellingborough and Rushden MP Peter Bone to prepare for a planning appeal hearing.
The inquiry will determine whether 124 new homes can be built in Irchester.
The hearing will take place at Wellingborough Council’s Swanspool House, in London Road, and is expected to take several days. It’s due will start on Tuesday, February 19.
Northampton-based Barwoods Strategic Land applied for planning permission last year to build up to 124 homes on land west of 124 High Street, Irchester, off Alfred Street.
The application was refused by Wellingborough Council, but following an appeal by the developer a Government planning inspector will now have the final say on whether it should go ahead.
Members of the public are free to attend the hearing.
The Save Irchester Village group fought a campaign to stop the development being built outside the village boundary.
More than 2,000 people signed a petition opposing the scheme.
Save Irchester Village chairman, Chris Stening said: “We are trying to rally support against this appeal because 2,000 turned people signed a petition against the development, 600 people opposed online, Irchester Parish Council didn’t want it and Wellingborough Council turned it down.
“We will fight it every step of the way.”
Peter Bone MP said: “This is part of an ongoing campaign to save Irchester village. We have now got to the appeal, which starts on Tuesday, February 19. It will be the first appeal that I have spoken at because I normally regard these sorts of things as a local government matter, but the council has said no to it and it touches on the issue of the over-development of our area.
It’s really important because we have go the Wellingborough east and the Wellingborough north developments, so we are providing the houses.
“They are trying to build outside the village boundaries and it would set a precedence, which is why I feel that I have got a right to speak.”
