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.
Three Brixton kitchen extension patterns
Three patterns cover most of what we build in SW2 and SW9. Single-storey rear extension on a Victorian terrace is the most common Brixton project. The terraces along Brixton Hill, Railton Road, Effra Road, and Acre Lane have a dark galley kitchen at the back, often with a piecemeal Victorian outrigger that's settled and is no longer worth keeping. We demolish the outrigger, extend 3-4 metres into the rear garden as a new structure, take out the load-bearing wall between kitchen and dining room with a 152x89 UC or 178x102 UB steel beam, and finish with bifolds across the new rear elevation. Cost is £50,000-£85,000 including foundations on London Clay (typically 1.0-1.2 metres on Brixton Hill, deeper on lower ground), structural steel, glazing, electrics, plumbing, and finishes. Build time 12-14 weeks. Side return infill on a wider Victorian terrace is the second pattern, 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 giving up rear garden space. Cost is £35,000-£60,000 including the structural roof, party wall foundations, glazing, and finishes. Build time 8-12 weeks. Party wall agreement with the neighbouring property is required. Wraparound extension on a wider terrace is the third pattern, suitable on the wider Victorian properties where both side return and rear projection are viable. Combines a 3-metre rear projection with a side return infill and creates 25-35 square metres of new open-plan space. Cost is £65,000-£100,000. Build time 14-18 weeks. The structural design typically uses a goalpost detail with two slimline steels meeting at the corner rather than one large beam.
Article 4 directions, Brixton conservation areas, and Victorian outriggers
Three Brixton-specific factors affect kitchen extensions and need checking before any quote. Article 4 directions on Lambeth streets. 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, 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 at Lambeth. We verify the planning status of each property on the Lambeth planning portal at the survey before quoting. Brixton, Rush Common, and Brixton Hill conservation areas. Three main residential conservation areas cover parts of SW2 and SW9. Within all three, exterior front-facing changes need sympathetic design and conservation officer review applies to visible alterations. Rear extensions are generally fine because they're not visible from the street. Lambeth Council can refuse retrospective consent for inappropriate changes. We check the boundary on the Lambeth planning portal at the survey before quoting. Victorian rear outriggers. Many Brixton Victorian terraces have piecemeal rear additions built over the decades — typically a Victorian outrigger that was tacked on as a scullery, then a 1950s flat-roof extension over the top, then a 1980s back-bedroom add-on. These structures often have settled foundations, single-skin walls, no insulation, and patched-up drainage. Rather than extending out from these compromised structures, we typically demolish the outriggers entirely and rebuild as a single new extension to current Building Regulations standards (Part A structure, Part L thermal performance to U-value 0.18 W/m²K). Adds £3,000-£6,000 to demolition and disposal cost compared with extending from sound existing walls, but produces a structurally and thermally sound result.
Lambeth Council process and project management
Brixton falls under Lambeth Council. Permitted development under Class A covers the 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 (£103, 6-8 weeks at Lambeth) on permitted development projects for written confirmation, which protects the property at sale time. A Brixton kitchen extension involves 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. We assign one project manager from survey through handover with photo updates throughout the build. Fixed-price contracts cover labour, materials, structural engineer calculations (£600-£1,200 for the steel and foundation design pack), Building Control fees (£400-£700 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. Building Control inspections happen at foundation, DPC, drainage, structural steel, insulation (Part L: U-value 0.18 W/m²K for new walls and roof), and completion. Glazing is FENSA-registered. Origin or Schüco bifolds and Crittall-style steel-frame doors are common on Brixton projects — Brixton clients often specify Crittall for the period character on conservation area properties. Roof construction is warm-roof with 150mm PIR insulation. 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.

Frequently Asked Questions
- How much does a Brixton kitchen extension cost?
- Single-storey rear extensions of 3-4 metres on Victorian terraces (the most common Brixton project) run £50,000-£85,000 including outrigger demolition, foundations, structural steel, glazing, electrics, plumbing, and finishes. Side return infill runs £35,000-£60,000. Wraparound extensions on wider terraces run £65,000-£100,000. Demolishing a piecemeal Victorian outrigger and rebuilding from scratch adds £3,000-£6,000 over extending from sound existing walls but produces a properly insulated and structurally sound result. Build Over Agreement with Thames Water adds £317 plus CCTV survey. Article 4 sites add the £206 planning fee and 4-6 weeks of lead time. Fixed-price contract before any work starts.
- 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 — the existing outrigger remains 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. Adds £3,000-£6,000 to demolition cost but 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 — 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. 57 verified Google reviews averaging 4.5/5.
