Planning appeal decision
Land at 118 Hawthorne Crescent, Slough, SL1 3NQ
Planning appeal 3293726 at Land at 118 Hawthorne Crescent, Slough, SL1 3NQ (Slough Borough Council) was dismissed on 23 June 2023 by Inspector Hawkins S, by written representations. The main issue, as the Inspector framed it: Whether the matters alleged in the enforcement notice have in fact occurred.
1. The unauthorised construction of a single-storey rear extension (as outlined in green on the plan attached to the notice) (‘the unauthorised rear extension’). 2. The unauthorised use of the single storey side extension as a self-contained unit of residential accommodation (‘the unauthorised use of the side extension). 3. The unauthorised use of the outbuilding (outlined in blue on the notice plan) as a separate dwelling (‘the unauthorised use of the outbuilding’)

Main issues, as the Inspector framed them
- Whether the matters alleged in the enforcement notice have in fact occurred
- Whether the matters alleged constitute a breach of planning control
- Whether it was too late to take enforcement action
- Whether the requirements of the notice are excessive
What decided it
The appellant failed to produce sufficiently clear and precise evidence that the rear extension was substantially completed or the outbuilding use began more than four years before the enforcement notice was issued, meaning neither matter was immune from enforcement action.
