Main issues, as the Inspector framed them

  • Whether the proposed side and rear dormer for loft conversion constitutes an alteration to the roof permitted under Class B of Part 1 of Schedule 2 of the GPDO, or whether it amounts to demolition and reconstruction of the roof

What decided it

The proposed works would constitute an alteration to the existing roof rather than construction of a new roof as a matter of fact and degree, because key structural elements of the hipped roof would remain in place and not be wholly removed.
