Planning appeal decision
Whistlebrook, Sewell Lane, Sewell, Bedfordshire, LU6 1RP
Planning appeal 3370896 at Whistlebrook, Sewell Lane, Sewell, Bedfordshire, LU6 1RP (Central Bedfordshire) was dismissed on 6 January 2026 by Inspector Hanson S, by written representations. The main issue, as the Inspector framed it: Whether the Council's refusal to issue a certificate of lawful use or development was well founded, turning on whether the proposal is development that materially affects the external appearance of the building and thus requires express planning permission.

Main issues, as the Inspector framed them
- Whether the Council's refusal to issue a certificate of lawful use or development was well founded, turning on whether the proposal is development that materially affects the external appearance of the building and thus requires express planning permission
What decided it
The proposed enclosure works would materially affect the external appearance of the building by creating substantial and sufficiently extensive physical changes visible from multiple normal vantage points, thereby constituting development requiring express planning permission rather than being excluded from the definition of development.
