Kitchen Extension Builders in Brixton (SW2, SW9)
Professional kitchen extension builders in Brixton, South London.
Why Choose All Well for Kitchen Extensions in Brixton?
Brixton's Victorian terraces — particularly on streets like Railton Road, Effra Road, and around Herne Hill borders — are classic kitchen extension candidates. The houses have that standard South London layout: separate kitchen and dining room at the back, both too small for modern life. We open it all up into one space, extend into the garden, and create a kitchen-diner that works for cooking, eating, homework, and everything else a family throws at it. Brixton clients tend to have strong opinions about design, which we love — it makes for better projects.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Brixton Homeowners
Lambeth Council covers Brixton, and they have Article 4 directions on some streets that remove permitted development rights. Always check before assuming your extension is permitted. The Brixton Conservation Area around Brixton Water Lane has specific requirements for materials and design. On the construction side, many Brixton terraces have rear additions that were built piecemeal over the decades — we often demolish these outriggers and rebuild as a single, properly designed extension.
Kitchen extension types we build in SW2 and SW9
Three patterns cover most of what we build in Brixton. The right one depends on your terrace width, garden depth, and whether you have an existing outrigger worth keeping.
Single-storey rear extensions on Brixton Victorian terraces
The most common project in SW2 and SW9. Terraces along Brixton Hill, Railton Road, Effra Road, and Acre Lane typically have a dark galley kitchen at the back, often with a piecemeal Victorian outrigger that has settled and is no longer worth keeping. We demolish the outrigger, extend 3–4 metres into the rear garden, take out the load-bearing wall between kitchen and dining room using a 152x89 UC or 178x102 UB steel beam, and finish with bifolds across the new rear elevation. Foundations go to 1.0–1.2 metres on Brixton Hill given London Clay conditions, deeper on lower ground. Build time is 12–14 weeks. Side return infill is common between Brixton Water Lane and Tulse Hill, where some properties have side returns of 1.0–1.5 metres. The infill creates a wider open-plan kitchen-diner without losing rear garden space. Party wall agreement with the neighbouring property is required. Build time 8–12 weeks. Wraparound extensions suit wider Victorian properties where both side return and rear projection are viable. A 3-metre rear projection combined with a side return infill creates 25–35 square metres of new open-plan space. Build time 14–18 weeks. Structural design typically uses a goalpost detail — two slimline steels meeting at the corner rather than one large beam.
Demolishing piecemeal Victorian outriggers in Brixton
Many Brixton Victorians have rear additions built in layers — a Victorian outrigger originally put up as a scullery, a 1950s flat-roof extension on top, a 1980s back-bedroom add-on stacked above that. These structures often have settled foundations, single-skin walls, no insulation, and patched-up drainage. Rather than extending out from compromised structures, we typically demolish the outriggers entirely and rebuild as a single new extension to current Building Regulations standards — Part A structure and Part L thermal performance to U-value 0.18 W/m²K. Demolishing and rebuilding rather than extending from sound existing walls means the result is structurally and thermally sound from end to end.
Article 4 directions and Brixton conservation areas — what to check before you start
Three Brixton-specific planning factors affect kitchen extensions. We check all three on the Lambeth planning portal at the survey stage, before quoting.
How Lambeth’s Article 4 directions affect rear extension planning in SW2
Lambeth has introduced Article 4 directions on streets in and around the Brixton, Rush Common, and Brixton Hill conservation areas. Article 4 removes specific permitted development rights and requires full planning permission for changes that would otherwise be permitted under Class A. They mainly affect front-of-property changes — cladding, window replacement, front-facing alterations — and rarely affect rear extensions. Where the direction does cover rear-elevation changes, the £206 full planning fee applies and lead time extends from 6–8 weeks to 10–12 weeks at Lambeth.
Conservation area requirements in the Brixton Water Lane and Rush Common areas
Three main residential conservation areas cover parts of SW2 and SW9 — Brixton, Rush Common, and Brixton Hill. Within all three, front-facing exterior changes need sympathetic design and conservation officer review applies to visible alterations. Rear extensions are generally fine because they are not visible from the street. Lambeth can refuse retrospective consent for inappropriate changes. Brixton clients often specify Crittall-style steel-frame doors for the period character on conservation area properties — we see that regularly on older streets near Brixton Water Lane.
Lambeth Council planning process and what the fixed-price contract covers
Brixton falls under Lambeth Council. Permitted development under Class A covers a standard 3-metre rear projection on a terrace and 4 metres on a semi or detached, except where Article 4 directions remove the right. The Larger Home Extension prior approval process covers 4–6 metre projections on terraces with an 8-week neighbour consultation. Lambeth typically determines applications in 8–10 weeks. We submit a Lawful Development Certificate (£129, 6–8 weeks at Lambeth) on permitted development projects — this gives written confirmation and protects the property at sale time.
Trades, inspections, and project management on a Brixton kitchen extension
A Brixton kitchen extension runs across 12–15 trades over 12–18 weeks: demolition of outriggers, foundations, drainage, structural steel, brick and block, roofing, glazing, plastering, electrics (NICEIC to BS 7671), plumbing, gas (Gas Safe), kitchen fitting, tiling, flooring, painting. One project manager runs from survey through handover with photo updates throughout. Building Control inspections happen at foundation, DPC, drainage, structural steel, insulation, and completion. Glazing is FENSA-registered. Where the extension projects over a Thames Water public sewer, a Build Over Agreement is required — £317 fee plus CCTV survey — and we handle the application. Fixed-price contracts cover labour, materials, structural engineer calculations for the steel and foundation design pack, Building Control fees at Lambeth, FENSA glazing registration, party wall surveyor coordination, conservation area applications where relevant, Article 4 full planning where required, outrigger demolition and disposal, and the Lawful Development Certificate or planning fee. Warm-roof construction uses 150mm PIR insulation to meet Part L.

Frequently Asked Questions
- What are Article 4 directions and how do they affect Brixton projects?
- Article 4 directions are local planning rules that remove specific permitted development rights in designated streets. Lambeth has introduced Article 4 directions on streets in and around the Brixton, Rush Common, and Brixton Hill conservation areas, typically requiring full planning permission for changes that would otherwise be permitted development. They mainly affect front-of-property changes (cladding, window replacement, front-facing alterations) and rarely affect rear extensions, but where the direction covers rear-elevation changes the £206 full planning fee applies and lead time extends from 6-8 weeks to 10-12 weeks. We verify the planning status of each property on the Lambeth planning portal at the survey before quoting.
- Should I demolish the existing rear outrigger on my Brixton terrace?
- Usually yes, on Victorian terraces with piecemeal rear additions. Many Brixton Victorians have a Victorian outrigger that was added as a scullery, with later flat-roof extensions or back-bedroom add-ons stacked on top. These structures typically have settled foundations, single-skin walls, no insulation, and patched-up drainage. Extending out from compromised structures means the new extension only meets current Building Regulations from the new structure outwards, leaving the existing outrigger thermally inefficient and structurally questionable. Demolishing the outrigger and rebuilding as a single new extension gives you a properly insulated, structurally sound result that meets Part A and Part L from end to end. It is the right call on most projects.
- Why hire All Well for a Brixton kitchen extension?
- Three reasons. First, accuracy: we know the SW2 and SW9 stock, the Article 4 boundaries, the Brixton, Rush Common, and Brixton Hill conservation areas, the piecemeal Victorian outrigger pattern that's typical on the older streets, and how Lambeth handles standard 3-metre projections. Second, full accreditation: NICEIC for electrical (BS 7671), FENSA for glazing, Gas Safe registered for boiler relocation, structural engineer calculations included, and Building Control sign-off included on every project. Third, fixed-price contracts: the quote doesn't change unless the specification does, including outrigger demolition, Build Over Agreement, party wall surveyor fees, and any Article 4 full planning.
