Main issues, as the Inspector framed them

  • Whether the Council's decision to refuse a certificate of lawful use or development was well-founded

What decided it

The resulting roof space volume of 64.47m³, including the existing dormer enlargement, exceeds the 40m³ limit permitted under GPDO Class B paragraph B.1(d)(i), meaning the proposal would not constitute permitted development.

The main issues and the deciding factor are read from the published letter by Town Planner Pro; the letter itself is the record. Contains public sector information licensed under the Open Government Licence v3.0. Research, not advice.
