Main issues, as the Inspector framed them

  • Whether the Council's decision to refuse to issue a certificate was well founded, turning on whether the proposed dormer extension and porch extension were developments permitted respectively by Classes B and D of Part 1 of Schedule 2 to The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended)

What decided it

The flashing between the porch roof and front wall of the house should not be included in the height measurement for Class D purposes, as it is not part of the practical structure and the GPDO must be interpreted in a practical context.
