Hi, The main issue, as Jeremy said, is that the loft is far too small at the moment to convert, which is why there's a problem. If only Southwark were a little more relaxed about raising the roof height! Another option I'm considering is leaving the master bedroom as is but only lowering the ceiling of the middle bedroom and hall (the bathroom and small back bedroom obviously already have much lower ceiling heights) - this might make enough space for a bathroom and a bedroom without having to do anything to the main (and nicest!) room. Does anyone know of someone who has done this kind of thing as a compromise? Ali - it's nice to hear of a positive result! Thanks for the offer - I'm still mulling things over at the moment but that could be really helpful a bit later on. Thanks.
