Background of the Development
The proposed 800-home scheme would transform the former Horsham Golf Club site in Southwater. Horsham District Council originally rejected the plan, citing its *unsuitable location* and limited active-travel links. However, the Secretary of State approved outline permission after a Planning Inspectorate report overturned the local decision, prompting immediate concern among councillors and residents.
Reasons for Judicial Review
The Council argues the Inspectorate made critical errors:
- Misinterpreting the National Planning Policy Framework, especially provisions on sustainable development.
- Incorrectly treating the Southwater Neighbourhood Plan as outdated.
- Failing to give proper weight to water neutrality and biodiversity net-gain requirements.
“We believe the decision undermines both local democracy and national planning policy,” a Council spokesperson stated.
Impact on Local Development
A successful judicial review could delay or even revoke permission, increasing uncertainty for other projects across Horsham District. Conversely, if the approval stands, developers may gain confidence to bring forward similar large-scale proposals, potentially accelerating housing delivery but heightening tensions over infrastructure capacity.
Role of the Neighbourhood Plan
The Southwater Neighbourhood Plan designates protected open space and imposes strict design criteria. The Council insists these community-backed policies deserve respect, emphasising that dismissing them would erode public trust in neighbourhood planning.
Sustainable Development & National Policies
Critics contend the development conflicts with sustainability aims by potentially harming biodiversity, overstretching water resources, and offering limited active-travel options. The Council claims national policies on water neutrality and climate mitigation were applied unevenly during the appeal.
Active Travel England’s Influence
*Active Travel England* advised on cycling and walking provisions within the project. The Council argues the recommendations were not fully adopted, leaving “token” pathways instead of comprehensive networks.
Community & Stakeholder Reactions
Local opinion remains split. Residents voice concerns about traffic, school places, and loss of green space, while developers highlight urgent housing demand. Southwater Parish Council has formally supported the judicial review, adding weight to the district’s case.
Next Steps & Potential Outcomes
The High Court will first decide whether to grant permission for the review to proceed. Possible scenarios include:
- Upheld approval – construction begins, establishing a powerful precedent.
- Quashed decision – the development returns to the planning stage.
- Partial ruling – clarification of policy interpretation without full annulment.
