SE18 primarily covers Woolwich / Plumstead in Greenwich.
Decisions for SE18 are made by Greenwich 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 Greenwich: No.
Building regs from £950. We do not charge hourly. Free site survey across all SE18 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. Greenwich Council timelines align with the national norm.
Woolwich / Plumstead in SE18 is characterised by the housing stock of Greenwich — broadly georgian in greenwich town centre.

Every SE18 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SE18 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SE18 | Woolwich / Plumstead | Georgian fragments, post-war estates, new-build | A drawing package at an SE18 address in Woolwich / Plumstead is determined by Greenwich Council under its own Local Plan policies for Woolwich / Plumstead. |
| SE18 | Woolwich | Georgian fragments, post-war estates, new-build | Woolwich sits inside SE18; drawing package proposals here are determined by Greenwich Council. |
| SE2 | Abbey Wood | mixed stock | Adjoining district to SE18, also inside Greenwich for drawing package purposes. |
| SE3 | Blackheath / Kidbrooke | Georgian villas, Victorian terraces | Adjoining district to SE18, also inside Greenwich for drawing package purposes. |
| SE7 | Charlton | Victorian villas, 1930s semi-detached | Adjoining district to SE18, also inside Greenwich for drawing package purposes. |
| SE9 | Eltham / Mottingham | 1930s semi-detached, post-war flats | Adjoining district to SE18, also inside Greenwich for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few SE18 streets, and each one changes what a drawing package can achieve at that address.
How designation changes a SE18 (Woolwich / Plumstead) drawing package: Greenwich Council maintains 20 conservation areas, including Eltham Park, Greenwich Town Centre (World Heritage Site), Blackheath. Inside any of them a SE18 (Woolwich / Plumstead) drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Charlton sets the tone for SE18 (Woolwich / Plumstead) casework.
No blanket Article 4 over SE18 (Woolwich / Plumstead): Greenwich Council has not withdrawn permitted development across SE18 (Woolwich / Plumstead), so a drawing package outside a SE18 (Woolwich / Plumstead) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a SE18 owner wants on file.
What SE18 (Woolwich / Plumstead) is built from: Georgian in Greenwich town centre; Victorian terraces in East Greenwich, Charlton; inter-war semi-detached in Eltham; new-build along the riverside. World Heritage Site status in Greenwich town centre adds heritage weight; outer borough areas (Eltham, Thamesmead) generally permissive. That mix decides the drawing package route in SE18 (Woolwich / Plumstead) more than the postcode does, and it is what a Greenwich Council case officer reads first. A householder application costs £548 paid to Greenwich Council direct, with 8 weeks to a decision once validated.
