Every Lewisham postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Lewisham fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SE13 | Lewisham / Hither Green | Victorian terraces, post-war flats | SE13 covers Lewisham / Hither Green only; Lewisham Council handles the drawing package, and Lewisham / Hither Green case officers apply the SE13 conservation-area map. |
| SE14 | New Cross | Victorian and Edwardian terraces across Brockley | New Cross sits wholly inside SE14, so Lewisham Council validates every drawing package submitted from an SE14 address. |
| SE23 | Forest Hill / Honor Oak | Victorian villas, Edwardian terraces | A drawing package at an SE23 address in Forest Hill / Honor Oak is determined by Lewisham Council under its own Local Plan policies for Forest Hill / Honor Oak. |
| SE26 | Sydenham | Victorian villas, Edwardian terraces | SE26 straddles a boundary: Sydenham addresses fall to Lewisham Council or Bromley Council, so confirm which authority validates the drawing package before submitting SE26 drawings. |
| SE3 | Blackheath / Kidbrooke | Georgian villas, Victorian terraces | Blackheath / Kidbrooke is split at SE3. Either Greenwich Council or Lewisham Council can determine a drawing package here, so the SE3 address is checked against both policies maps first. |
| SE4 | Brockley | Victorian and Edwardian terraces | A drawing package at an SE4 address in Brockley is determined by Lewisham Council under its own Local Plan policies for Brockley. |
| SE6 | Catford / Bellingham | 1930s semi-detached, post-war flats | SE6 covers Catford / Bellingham only; Lewisham Council handles the drawing package, and Catford / Bellingham case officers apply the SE6 conservation-area map. |
| SE8 | Deptford | Georgian terraces, post-war estates, new-build | Deptford sits wholly inside SE8, so Lewisham Council validates every drawing package submitted from an SE8 address. |
Roof pitch, wall build-up and plot depth change every few Lewisham streets, and each one changes what a drawing package can achieve at that address.
How designation changes a Lewisham drawing package: Lewisham Council maintains 30 conservation areas, including Lee Green, Blackheath, Deptford High Street. Inside any of them a Lewisham drawing package cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Deptford High Street sets the tone for Lewisham casework.
No blanket Article 4 over Lewisham: Lewisham Council has not withdrawn permitted development across Lewisham, so a drawing package outside a Lewisham conservation area usually keeps it. The £129 Lawful Development Certificate is still the document a SE4 owner wants on file.
What Lewisham is built from: Victorian and Edwardian terraces across Brockley, Honor Oak, Forest Hill; 1930s semi-detached in Catford and Hither Green; post-war mixed in Deptford. Generally permissive planning compared to central boroughs; loft conversions and side-return extensions routinely approved under PD. That mix decides the drawing package route in Lewisham more than the postcode does. Our fixed fee for architectural drawings in Lewisham starts at £840, against £1,750 for the Complete package that carries a Lewisham scheme through Lewisham Council planning and building regulations together.
