rcbGroup projectLoft Conversions in Lewisham — what to expect
Loft conversions in SE4, SE13 and SE6 are predominantly rear dormers. The Brockley conservation area in SE4 means planning applications are required for many conversions. SE13 and SE6 have higher PD availability. Hip-to-gable is possible on the semi-detached stock in Grove Park and Hither Green.
Lewisham property types
Victorian and Edwardian terraces (Brockley, Catford, Ladywell), interwar semis in the south. The property type affects which loft conversion approach works best — we'll advise from the first call.
