What PlanWatch Is Tracking in Horsham
PlanWatch currently holds 1,941 Horsham planning records across 962 unique postcode locations, with tracked application dates from 2026-01-12 to 2026-10-26. The most common categories in this dataset are Full (975), Householder (262), Demolition (161).
Use this page to start with a postcode search, then open the official council record for the decision notice, drawings, consultation deadline and any later conditions. That matters because a short application description rarely shows the details neighbours and buyers care about: side windows, roof forms, access, drainage, tree works, opening hours or amended plans.
Planning Battles in Horsham
Notable planning controversies and disputes that have shaped development in the Horsham area.
Denne Hill 800-Home Development
2025Planning Inspectorate granted outline permission for 800 homes on former Horsham Golf and Fitness site between Southwater and Horsham. Council had refused in May 2024 citing unsustainable location. Inspector 'blasted' council's 'lamentable' 2.2-year housing land supply. Judicial review rejected in October 2025. Over 3,500 petition signatures from Keep Denne Hill Green campaign.
Why this matters: This shows how low housing supply leads to successful appeals on unallocated sites. Monitoring supply levels predicts vulnerability to speculative applications.
Local Plan Withdrawal
2025Horsham's Local Plan 2023-2040 faced withdrawal after Inspector found failure in 'Duty to Cooperate'. Failed to adequately engage neighbouring authorities on cross-boundary housing needs (Crawley's unmet 7,500 home demand). Also failed on water neutrality solutions in Sussex North Supply Zone. Council recommended withdrawal in July 2025.
Why this matters: Local Plan failures leave district without up-to-date plan, making it vulnerable to speculative applications. Monitoring would track plan progress and inspector concerns.
Thakeham 247-Home Blocked
2025Council successfully blocked plans for 247 homes in Thakeham parish. Planning Inspectorate dismissed developer's appeal, citing incompatibility with local character and infrastructure deficits. Rare win for council against speculative growth.
Why this matters: This shows successful resistance is possible. Monitoring would identify similar opportunities where appeals might fail.
