Decision & conditions

Non-material amendment(s) not agreed
dn final
Planning conditions
  1. REASON: The proposed amendments, specifically the amendments to the dormer, would constitute a material change to the original planning permission P2025/2186/FUL and would require full planning permission. As such, it is recommended that a S96A application is refused as the non-material amendments are not agreed.
