vik2001 Posted March 12 Share Posted March 12 Question for a Prior Notification for Single Storey side extension to go up to 8metres, is it still the case you can't go above the original eaves height with a flat roof? Link to comment Share on other sites More sharing options...

efkor Posted March 12 Share Posted March 12 The eaves of the extension (any roof type) cannot go higher than the eaves of the original house. Prior approval is for rear extensions, but note that the 8m you quote is for detached houses only. If you need more info, I have done a whole series of Permitted Development videos that some Buildhub members have found useful (youtube/efkor) 1 Link to comment Share on other sites More sharing options...

I will be picking your brains in the near future as I’m just in the process of buying another place. Link to comment Share on other sites More sharing options...
vik2001 Posted March 12 Author Share Posted March 12 (edited) OK thanks. I'm.exploring options and to gain general knowledge. I'm within 2m of a boundary if the flat roof was designed like below would I be within PD for the height, any workarounds Edited March 12 by vik2001 Link to comment Share on other sites More sharing options...
DevilDamo Posted March 12 Share Posted March 12 That is a common detail/build-up for a warm flat roof. It would meet the max. 3m PD eaves height. Just as a side note and on that particular example, it looks to be a flat roof extension on a bungalow which are more difficult to get through PD. A different story when attaching to a two storey house. Link to comment Share on other sites More sharing options...
vik2001 Posted March 12 Author Share Posted March 12 That is the drawing my architect drew for my bungalow. Why is it difficult to get through pd? Link to comment Share on other sites More sharing options...
DevilDamo Posted March 12 Share Posted March 12 The eaves of the flat roof exceed the eaves of the main roof. Well they do in that drawing. I don’t know what other eaves there may be to relate or compare to. 1 Link to comment Share on other sites More sharing options...
vik2001 Posted March 13 Author Share Posted March 13 Is there any workaround for this issue. What if I didn't use a flat roof and used a pitched roof would it solve the issue. Link to comment Share on other sites More sharing options...
DevilDamo Posted March 13 Share Posted March 13 Lower the flat roof or introduce a pitched roof. Your Architect should be able to advise how to comply with PD. But going from your other post, the overall depth would fail to meet the PD requirements. Unless this is a different extension? Link to comment Share on other sites More sharing options...

No it's the same extension, I will ask architect if a pitched roof will solve the issue Link to comment Share on other sites More sharing options...
DevilDamo Posted March 13 Share Posted March 13 But the depth does not comply. So the roof design is irrelevant. Link to comment Share on other sites More sharing options...
vik2001 Posted March 31 Author Share Posted March 31 I will get my decision in 4 weeks time. If it doesn't go through I'm planning just to limit the extension down to 3m or 6m and introduce a pitched roof to get it through PD. Will doing a proper pitched roof rather than a flat roof pass PD and get me the ceiling height? Link to comment Share on other sites More sharing options...
DevilDamo Posted March 31 Share Posted March 31 The ceiling height is irrelevant. The height of the eaves should not exceed existing. So if you comply with that, then that’s one requirement met. An extension with a depth more than 4m requires Prior Approval. An extension with a max. depth of 4m is usually PD. Link to comment Share on other sites More sharing options...
vik2001 Posted March 31 Author Share Posted March 31 Thanks DD. Just to confirm even with prior approval is it still the case the height of the eaves cant exceed existing? Link to comment Share on other sites More sharing options...
DevilDamo Posted March 31 Share Posted March 31 Yes. The only difference with PA is the increased depth from 3m to 6m or 4m to 8m. 1 Link to comment Share on other sites More sharing options...
vik2001 Posted March 31 Author Share Posted March 31 Thanks dd. One last bit of advice if I didn't get planning and tried to do a 3m extension under PD, can the height of new eaves exceed existing if using a pitched roof? I understand this isn't the case with a flat roof. Link to comment Share on other sites More sharing options...
DevilDamo Posted March 31 Share Posted March 31 It doesn’t matter if it’s a flat or pitched roof. The new eaves cannot exceed the existing. 1 Link to comment Share on other sites More sharing options...
