Lewisham controls the Corbett Estate and Ladywell conservation areas; SE13 is a strong, well-priced family-extension market.
If your property sits elsewhere in the borough, the borough-wide page for building regulations drawings in Lewisham covers the same service across every ward.
Building regulations drawings for a Lewisham project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Lewisham Council Building Control or an approved inspector. On SE13's victorian and edwardian terraces and bay-fronted houses, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Lewisham, Hither Green, Ladywell, Blackheath fringe.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Across Lewisham, Hither Green, Ladywell, Blackheath fringe in SE13, the dominant property is victorian and edwardian terraces and bay-fronted houses around lewisham and hither green, with post-war estates and new-build near the centre. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Lewisham Council judges each on design quality and neighbour impact. We survey the specific Lewisham property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SE13 streetscape.

Usually yes outside the conservation areas — a rear dormer or L-shape over the back addition within the volume allowance, confirmed by a Lawful Development Certificate. Inside the Corbett Estate or Ladywell designations, roof changes need full planning. We confirm which applies to your road.
