Hey all, this is a really interesting thread. We've got a proposal in with planning at the moment to convert our butterfly roof. Following pre-planning advice (where they said it basically wouldn't ever happen because of the v, being in an unbroken line of butterfly roofs and seeing the structure from the street) we went back to the drawing board. We now have a proposal that can't be seen from the street, doesn't rise above parapet, doesn't destroy the v and isn't too big. Because various dormers have been put on the back of some of the houses, the look has already been spoilt. Now the only sticking point is the existing roof structure. We've been told if we can show some examples of successful conversions - especially in rows of London roofs, we MIGHT be in with a chance. Possibly. Does anyone know of anyone who has had success? I'll look at the suggested Nutfield road, choumert road and crystal palace road, thanks!
