Northampton borough councillors have unanimously voted to make objections to a massive homes plan to the north of the town.
Developers Ensign Group Limited wants to build an additional 674 homes on land at Brampton Lane, Boughton as the next part of the Buckton Fields development.
When complete, the development will plant a total of 1,050 homes in the area, with a care home, a park and ride facility and an academy primary school.
Buckton Fields has been met with criticism by Northampton folk and residents' associations, who want infrastructure to be put in place to cope with the potential thousands of new people.
But ahead of a planning committee meeting on Tuesday (November 21), planning chiefs recommended they would hold no objection to the plan.
Councillors immediately protested the idea and said Northampton is not ready to accept the huge influx of people until North West Relief Road project is complete.
Now, after a vote by the unanimous vote by the committee, the borough council will raise objections as there was "no support for the development until the infrastructure was in place".
The plan will have no formal objections to the houses themselves.
The 1,050 houses are inside the boundaries of Daventry District Council, who will get final say over the plans and invited Northampton Borough Council to be a "key consultee".
Ward councillor for Kingsthorpe Sally Beardsworth says the town is getting the short end of the deal.
She said: "We absolutely do have objections. We just can't have these houses until the infrastructure is in place.
"These houses have been dumped on us by Daventry District Council. They will get all the taxes and money from building houses and we [Kingsthorpe] will get all the pain. Those new residents will put so much pressure on Northampton.
"I am not opposed to new houses but we must have the Relief Road completed as soon as possible first."
During "phase two" of Buckton Fields, a total of 380 homes have been built on Brampton Lane.
The North West Relief Road, together with the Northern Orbital Route, aim to ease traffic in Northampton by completing the town's ring road.
However, the project was delayed another month earlier in November after a record number of responses to the consultation from Northampton folk.
