Planning Drawings · SE4 Brockley
Lewisham controls the large Brockley conservation area, one of south London's most extensive; the bay-fronted villas are a strong extension market.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read planning drawings in Lewisham.
Planning drawings for Brockley start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Lewisham Council. On SE4's victorian terraces and bay-fronted villas around brockley, the recurring questions are roof additions, rear and side-return extensions, and alterations within Brockley, Crofton Park / Ewhurst. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Brockley, Crofton Park, Honor Oak fringe, Ladywell fringe.
Across Brockley, Crofton Park, Honor Oak fringe, Ladywell fringe in SE4, the dominant property is victorian terraces and bay-fronted villas around brockley, with conservation streets on the hill and post-war pockets toward crofton park. That stock shapes what planning permission 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 Brockley property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SE4 streetscape.

Streets we know in SE4: the Brockley Conservation Area roads (Wickham Road, Tressillian Road), Breakspears Road and the Crofton Park streets. Each road has its own building line, boundary treatment and precedent that Lewisham Council weighs when assessing a planning permission drawings scheme.
Conservation areas: Brockley, Crofton Park / Ewhurst. Inside these, most external work needs full planning and a Heritage Statement.
Getting around SE4: Brockley and Crofton Park on the Overground and Thameslink to London Bridge.
Property values: £558,750 was the median SE4 sale price on the 2025 price-paid returns, from 346 transactions. It reads high against Lewisham as a whole, where the median across 3,101 sales was £470,000.
Borough character: Generally permissive planning compared to central boroughs; loft conversions and side-return extensions routinely approved under PD.

Listed, conservation or complex sites.
Yes. The bay-fronted villas and terraces around Wickham Road and Tressillian Road suit side-return and rear extensions and loft conversions, but much of SE4 sits in the Brockley conservation area, so changes there need full planning with a Heritage Statement. We design to match the period detailing and submit to Lewisham.
It is one of south London's largest, covering a great many of the Victorian streets around Brockley and Crofton Park, with controls on materials, bays, front gardens and roofscape. We check whether your exact road falls within it, because that decides whether you need full planning rather than a Lawful Development Certificate.
Outside the conservation area, usually yes — a rear dormer or L-shape within the volume allowance, confirmed by a Lawful Development Certificate. Inside the Brockley designation, roof changes need full planning and are assessed on the roofscape impact. We confirm which applies to your road.
With SE4 houses around £700,000-£1m and Overground and Thameslink links to the City, a side-return or loft adds family space worth comfortably above the build and drawing cost. Brockley's strong period character keeps demand high.
Lewisham Council charges its own statutory application fee (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every SE4 address.
For a SE4 project across Brockley, Crofton Park, Honor Oak fringe, Ladywell fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Lewisham Council (8 weeks for a householder application). We carry the Brockley application through every officer query to the decision.
Brockley (SE4) sits primarily in Lewisham, so applications are decided by Lewisham Council. Conservation areas within SE4 include Brockley, Crofton Park / Ewhurst, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind planning permission drawings in Brockley — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Lewisham Council Building Control or an approved inspector. On SE4's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on SE4 homes.
Planning history and precedent stop at the borough line, so the comparable approvals nearby may sit elsewhere. See all services in SE3, SE6, SE12, SE13, SE23 and SE26.

Every SE4 postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. SE4 fees below are the statutory England rates for 2026, not planning drawing set estimates.
| Postcode | Area | Dominant stock | What it means for a planning drawing set |
|---|---|---|---|
| SE4 | Brockley | Victorian and Edwardian terraces | A planning drawing set 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 | Adjoining district to SE4, also inside Lewisham for planning drawing set purposes. |
| SE8 | Deptford | Georgian terraces, post-war estates, new-build | Adjoining district to SE4, also inside Lewisham for planning drawing set purposes. |
| SE12 | Lee / Grove Park | mixed stock | Adjoining district to SE4, also inside Lewisham for planning drawing set purposes. |
Roof pitch, wall build-up and plot depth change every few SE4 streets, and each one changes what a planning drawing set can achieve at that address.
SE4 (Brockley) conservation designations: there are 30 across Lewisham Council, Forest Hill, Hither Green, Lee Green among them. Designation costs a SE4 (Brockley) owner the permitted-development route: a planning drawing set then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Hither Green is the SE4 (Brockley) designation that most often changes a planning drawing set design.
Article 4 and your SE4 (Brockley) planning drawing set: Lewisham Council has made no borough-wide direction, so permitted development for a planning drawing set in SE4 (Brockley) generally survives outside SE4 (Brockley) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SE4 owner records that a planning drawing set was lawful.
The building fabric around SE4 (Brockley): 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 planning drawing set in SE4 (Brockley) 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.
