Main issues, as the Inspector framed them

• Appeal A: Whether the Council's refusal to grant a certificate of lawful use or development was well-founded, turning on whether the applicant has shown that the GPDO grants planning permission for the proposal at Article 3, Schedule 2, Part 1, Classes A, B and C
• Appeal B: Whether the proposed single storey rear extension would amount to inappropriate development in the Green Belt, having regard to the Framework and the Development Plan
• Appeal C: Whether the proposed rear dormer would amount to inappropriate development in the Green Belt, having regard to the Framework and the Development Plan
• Appeal D: Whether condition No 8 is necessary and reasonable in the interests of safeguarding the openness and visual qualities of the Green Belt

What decided it

For Appeals B and C, the extensions and dormer would not be disproportionate to the original building and would not harm Green Belt openness, making them appropriate development consistent with the Framework. For Appeal A, condition 8 validly removes permitted development rights and continues to bind subsequent versions of the GPDO. For Appeal D, condition 8 is necessary and reasonable given the circumstances of the replacement dwelling and the need to protect Green Belt openness.
