Oxford City Council’s proposal to expand its borders and build tens of thousands of homes on Green Belt land has sparked sharp debate across Oxfordshire. Supporters say the move could ease the housing crisis and cut congestion; opponents argue it risks undermining transport planning and sacrificing countryside.
A plan for “Greater Oxford”
Under proposals for local government reorganisation, Oxford City Council plans to create a “Greater Oxford” authority by expanding its boundaries to incorporate nearby villages such as Kidlington, Cumnor and Wheatley.
City leaders say this would unlock land for up to 40,000 homes on what they call “poor quality” Green Belt. They argue that housing built closer to jobs in the city would reduce long commutes and take cars off the A34, A40 and A44.
Councillor Anna Railton, Oxford’s deputy leader, said:
“Building homes in walking and cycling distance from jobs would mean thousands fewer cars on the A34, A40 and A44.”
City council leader Susan Brown added:
“Even building 40,000 new homes, the overwhelming majority of the Green Belt would remain untouched.”
Brown also suggested the city’s Green Belt could theoretically host up to three million homes, but stressed that most of the land would still remain open under the Greater Oxford proposal.

County council pushback
The idea has been strongly criticised by Oxfordshire County Council, which favours creating a single county-wide unitary authority instead of three new local councils.
Councillor Andrew Gant, the county’s transport chief, warned:
“Placing a boundary between competing transport authorities all around Oxford in every direction will make transport worse, not better.”
He also accused the city of failing to allocate sufficient housing within its existing borders, forcing development further out:
“A large part of the reason why congestion is still a problem in our county is the city council’s repeated and historic refusal to prioritise sufficient housing on its own key strategic sites. That leads directly to development further out, and increased pressure on commuter routes.”
County council leader Liz Leffman added:
“Having one council for the county would create stronger, simpler services that are closer to communities, cost effective and connected.”
Transport and congestion
The stakes are high. The A34, A40 and A44 are among the most congested roads in southern England, carrying thousands of commuters daily from expanding towns such as Didcot, Bicester and Witney.
City leaders say building closer to Oxford would shift more journeys to walking and cycling. The county argues that competing authorities would fracture transport planning and hinder efforts to deliver joined-up bus and rail investment.
Governance: two competing visions
- City plan: Create a Greater Oxford authority, enabling selective Green Belt development on the city fringe.
- County plan: Form a single unitary council for the whole county, simplifying services and transport decisions.
Both sets of proposals are due to be submitted to Government in November 2025. Ministers are expected to decide in 2026, with new councils created by 2028.
Lessons from Oxfordshire Plan 2050
The row follows the collapse of the Oxfordshire Plan 2050, a joint strategy that was meant to set housing numbers across all districts. Councils could not agree whether to plan for around 100,000 or 150,000 homes by mid-century.
Its failure highlighted the difficulties of balancing housing demand with countryside protection, a theme now resurfacing in the Green Belt dispute.
Why it matters
The Greater Oxford proposal brings three competing visions into sharp relief:
- City leaders see limited Green Belt release as essential to easing Oxford’s housing shortage and cutting congestion.
- County leaders fear it will create fragmented governance and worsen transport problems.
- National Government will decide which vision prevails, shaping the future of Oxfordshire’s growth.
With decisions due by the end of the decade, the outcome will determine not just how many homes are built, but who controls Oxfordshire’s development.
