Solihull could be swamped with even more homes campaigners fear after Birmingham City Council bosses announced they will need help from neighbouring areas to meet their housing needs.
The concerns follow the release of the Birmingham Development Plan Consultation, which sets out plans for 80,000 homes to house a larger than expected population growth of 150,000 people for the next 21 years.
The document states the city is working with neighbouring authorities through the duty to cooperate scheme to share some of the housing requirements.
Councillor Jim Ryan (Con, Bickenhill) said: "I have always been concerned about further development within Solihulls greenbelt. We have taken without question our fair share of residential development.
"I fully support Birmingham and the people who live there but there are massive areas of land which could be used in the city before they start eyeing up Solihull.
"We have our own local plan and houses to allocate and the thought of Solihull being targeted further would be wholly wrong."
Linda Poulson, from the action-group Marston Green Optimising Our Development (MGOOD), added: "We would be horrified if this happened. Our village is right on the border with Birmingham and weve got enough problems as it is trying to accommodate housing."
However a spokesman for Birmingham City Council said the consultation does not feature Solihull and the authority will be concentrating on siting 30,000 homes in parts of the Sutton Coldfield area.
