Hello,
Been using the site for several years and pickup up good advice.
I am planning to put a hip to gable box dormer under PD (semi=50m3). Also I intend to put a part 2 storey and part single at rear first and at a later stage a 2storey side (maybe).
1. "Development is permitted by Class B subject to the following conditions:
(ii)other than in the case of an enlargement which joins the original roof to the roof of a rear or side extension, no part of the enlargement extends beyond the outside face of any external wall of the original dwellinghouse; and
Interpretation of Class B
B.3 For the purposes of Class B, “resulting roof space” means the roof space as enlarged, taking into account any enlargement to the original roof space, whether permitted by this Class or not."
My understanding is that the 2 storey side and 2 storey rear roof constructions would not count towards the 50m3, as the the dormer and the reconstructed roof would only be on the original house, or is am I getting it wrong way round?
2. The rear part 2 storey part single to the original house would have a flat roof? as it would not be possible to construct a 'v' shape sloping roof originating from the original roof since the box dormer is in the way?
I have been through the site and other sites, and I getting conflicting messages as some say, do the loft dormer first (PD), other places, I read, do the extensions first, then do the loft under PD. If I did the rear extensions first, I would have to redo the roof for 2 storey to a flat roof.
Your ideas highly welcome, Many thanks
