Plans to build 600 new homes near a market town have been unveiled.
Developer Taylor Wimpey is preparing an outline plan for the development on land south of Green Lane, in Yarm.
The firm is holding a two-week consultation on the plans which include building two to five-bedroom homes, including up to 20% of affordable housing as well as homes to rent.
Stockton West Conservative MP Matt Vickers said he was against the "barmy" development and there were already too many properties in the town.
Taylor Wimpey says feedback from the consultation will shape the planning application which it intends to submit to Stockton Borough Council in the summer, the Local Democracy Reporting Service said.
Vickers said: "The idea of building yet more housing in Yarm is utterly barmy.
"In recent years the Labour council has allowed the packing, stacking and racking of thousands of homes on green field sites and created unbearable pressure on our local infrastructure, from roads to schools to healthcare services.
"We must ensure Yarm's unique character is preserved."
The council said it could not comment on the proposals because it had not yet received a planning application.
An exhibition event will be held at Yarm Sports and Social Club on Leven Road on Thursday between 15:00 and 19:00 BST.
