Professional kitchen extension builders in Catford, South East London.

Why Choose All Well for Kitchen Extensions in Catford?
Catford is where renovation meets value for money. The Victorian terraces and Edwardian semis here are solidly built, and the prices are lower than neighbouring Lewisham and Forest Hill — which means you can afford to invest in a proper kitchen extension and still come out well ahead. We've done plenty of these in SE6, and the typical project is a 3-4 metre rear extension that transforms a dark, separate kitchen into an open-plan space that faces the garden.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Catford Homeowners
Lewisham Council covers Catford and they're supportive of residential extensions. The Culverley Green conservation area has some additional requirements, but most of Catford is outside conservation zones. Properties near the Ravensbourne river corridor may need a Flood Risk Assessment — check the Environment Agency maps before committing to a design. On the positive side, the gravel subsoil near the river often means shallower foundations than the clay found on higher ground.
Three Catford kitchen extension patterns
Three patterns cover most of what we build in SE6. Single-storey rear extension on a Victorian terrace is the most common Catford project. The terraces along Sangley Road, Brownhill Road, Inchmery Road, and the streets near Catford Bridge have a dark galley kitchen at the back. We extend 3-4 metres into the rear garden, take out the load-bearing wall between the kitchen and the dining room with a 152x89 UC steel beam, and finish with bifolds across the new rear elevation. Cost is £45,000-£75,000 including foundations on Catford's mixed clay and Ravensbourne gravel (typically 1.0-1.2 metres on standard sites), structural steel, glazing, electrics, plumbing, and finishes. Build time 10-14 weeks. Permitted development under Class A covers the standard 3-metre projection. Wraparound extension on an Edwardian semi is the second pattern, common on the streets near Manor Park and the wider plots around Catford Bridge. Combines a 3-metre rear projection with a side return infill on the side away from the neighbour. Creates 25-32 square metres of new open-plan space. Cost is £60,000-£95,000. Build time 12-16 weeks. The Edwardian semis often have cavity walls, which makes new insulation tie-in straightforward. Side return infill is the third pattern, common on the wider Victorian terraces with side returns of 1.0-1.4 metres. Cost is £32,000-£55,000 including the steel-framed roof structure, party wall foundations, glazing, and finishes. Build time 8-12 weeks. Party wall agreement with the neighbouring property is required because the side return sits on the shared boundary wall.
Catford structural detail — Ravensbourne floodplain, Culverley Green, mixed subsoil
Three Catford factors affect kitchen extensions and need checking before any quote. Ravensbourne and Pool River flood zones. Properties near the Ravensbourne river corridor or the Pool River may sit in Flood Zone 2 or 3 and need a Flood Risk Assessment as part of the planning application for any new extension. The Environment Agency's flood risk maps confirm the zone designation, and we check this at the survey before quoting. Cost of the assessment is typically £600-£1,200. Some riverside properties also need flood resilience measures (raised electrical sockets, water-resistant materials below 600mm) which add £2,000-£5,000 to extension cost. Most of Catford's higher-ground streets (away from the river corridor) are outside flood zones. Culverley Green conservation area. The small Culverley Green conservation area covers streets just east of Catford town centre. Within the area, exterior front-facing changes need sympathetic design, and Lewisham Council can act on retrospective unauthorised changes. Rear extensions are generally fine because they're not visible from the street. Most Catford streets are outside the conservation area and have full permitted development rights. Lewisham also has Article 4 directions on some streets near the conservation area boundary — we verify the planning status of each property before quoting. Mixed subsoil with Ravensbourne advantage. SE6 sits on London Clay across most of the borough, with pockets of river-terrace gravel near the Ravensbourne corridor. Properties on gravel typically need foundations of 0.9-1.0 metres rather than the 1.2-1.5 metres needed on clay — saves £1,000-£2,500 on groundwork on gravel sites. We dig a trial hole at the survey on every project where ground conditions aren't already known from a neighbouring job we've completed. The structural engineer specifies the foundation depth from the data, and the cost is firm before the contract is signed.
Lewisham Council process and project management
Catford falls under Lewisham 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 and 4-8 metres on semis or detached, with an 8-week neighbour consultation. We submit a Lawful Development Certificate (£103, 6-8 weeks at Lewisham) on every permitted development project for written confirmation, which protects the property at sale time. A Catford kitchen extension involves 12-15 trades over 10-16 weeks: demolition, 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-£600 at Lewisham), FENSA glazing registration, party wall surveyor coordination (Agreed Surveyor route on terraces), Flood Risk Assessment where applicable, conservation area applications where relevant, trial hole investigation, 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 Sieger sliders are common on Catford projects. Catford specifications typically run mid-range — Caesarstone or Silestone worktops, kitchen joinery from Howdens or Magnet, mid-spec appliances. Underfloor heating across the new floor is standard. 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 Catford kitchen extension cost?
- Single-storey rear extensions of 3-4 metres on Victorian terraces (the most common Catford project) run £45,000-£75,000 including foundations, structural steel, glazing, electrics, plumbing, and finishes. Wraparound extensions on Edwardian semis run £60,000-£95,000. Side return infill on wider Victorian terraces runs £32,000-£55,000.

Properties on Ravensbourne river-terrace gravel typically save £1,000-£2,500 on foundations versus equivalent clay sites. Fixed-price contract before any work starts.
- Do I need a Flood Risk Assessment for a Catford extension?
- Possibly, depending on flood zone. Properties near the Ravensbourne river corridor or the Pool River may sit in Flood Zone 2 or 3 and need a Flood Risk Assessment as part of the planning application for any new extension. The Environment Agency's flood risk maps confirm the zone designation, and we check this at the survey before quoting. Cost is typically £600-£1,200 and we coordinate it as part of the planning process. Some riverside properties also need flood resilience measures (raised sockets, water-resistant materials below 600mm) which add £2,000-£5,000 to extension cost. Most of Catford's higher-ground streets (away from the river corridor) are outside flood zones and don't need an assessment.
- Does the Culverley Green conservation area affect kitchen extensions?
- Only on properties within the boundary. The small Culverley Green conservation area covers streets just east of Catford town centre. Within the area, exterior front-facing changes (window replacement, render colour, front door changes) need sympathetic design and Lewisham Council can act on retrospective unauthorised changes. Rear extensions are generally fine because they're not visible from the street. Most Catford residential streets are outside the conservation area and have full permitted development rights for the standard rear extension. Lewisham also has Article 4 directions on some streets near the boundary — we check the conservation area boundary and Article 4 register on the Lewisham planning portal at the survey before quoting.
- Why hire All Well for a Catford kitchen extension?
- Three reasons. First, accuracy: we know the SE6 stock — which streets have Ravensbourne flood risk, where the Culverley Green conservation area runs, which sit on river-terrace gravel rather than clay, and how the Lewisham planning process 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 Flood Risk Assessment, Build Over Agreement, trial-hole foundation reassessment, and party wall surveyor fees. 57 verified Google reviews averaging 4.5/5.
