SE8 primarily covers Deptford in Lewisham.
Decisions for SE8 are made by Lewisham Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Lewisham: No.
Building regs from £950. We do not charge hourly. Free site survey across all SE8 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Lewisham Council timelines align with the national norm.
Deptford in SE8 is characterised by the housing stock of Lewisham — broadly victorian and edwardian terraces across brockley, honor oak, forest hill.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SE8 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SE8 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| 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. |
| SE4 | Brockley | Victorian and Edwardian terraces | Adjoining district to SE8, also inside Lewisham for drawing package purposes. |
| SE6 | Catford / Bellingham | 1930s semi-detached, post-war flats | Adjoining district to SE8, also inside Lewisham for drawing package purposes. |
| SE12 | Lee / Grove Park | mixed stock | Adjoining district to SE8, also inside Lewisham for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few SE8 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering SE8 (Deptford): Lewisham Council runs 30, and Lee Green, Blackheath, Deptford High Street are the ones SE8 (Deptford) owners meet most. A drawing package inside a SE8 (Deptford) conservation area loses permitted development, so the SE8 (Deptford) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Hither Green a drawing package is judged on the street elevation first.
No blanket Article 4 over SE8 (Deptford): Lewisham Council has not withdrawn permitted development across SE8 (Deptford), so a drawing package outside a SE8 (Deptford) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a SE8 owner wants on file.
The building fabric around SE8 (Deptford): 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. A drawing package in SE8 (Deptford) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Lewisham Council.
