Kitchen Extension Builders in Battersea (SW11, SW8)
Professional kitchen extension builders in Battersea, South West London.
Why Choose All Well for Kitchen Extensions in Battersea?
Battersea kitchens are the reason half our clients call us. The Victorian terraces between Clapham Junction and Battersea Park have that classic London problem — a dark galley kitchen that was fine in 1890 but doesn't work for a family in 2026. We open up the rear wall, add 4-5 metres of extension with bifold doors, and suddenly you've got a room where people actually want to spend time. We've done enough of these in SW11 to know exactly what the steelwork, drainage, and Building Control process looks like here.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Battersea Homeowners
If your Battersea terrace backs onto a railway line or shared alley, access for skip lorries and concrete pumps gets complicated fast. We always do an access survey before pricing — some streets in SW11 need a smaller pump and hand-carried materials, which adds a day or two to groundwork. Also worth knowing: Wandsworth Council's planning team is one of the quicker ones in London, and most rear extensions sail through under permitted development.
Three Battersea kitchen extension patterns
Three patterns cover most of what we build in SW11. Single-storey rear extension is the most common. The Victorian terraces around Northcote Road, Lavender Hill, and the streets towards Battersea Park have classic dark galley kitchens that get transformed by 4-5 metre rear extensions with bifold doors and roof lanterns. Cost is £55,000-£90,000 including structural steelwork, foundations on Battersea clay (typically 1.2-1.5 metres), glazing, electrics, plumbing, and finishes. Build time 12-14 weeks. Wandsworth's permitted development process covers the standard 3-metre rear extension on terraces. Wraparound extension is the second pattern, common on the wider Victorian terraces with side returns of 1.0-1.5 metres. Combining the side return infill with a rear extension creates an open-plan kitchen-diner of 30-40 square metres. Cost is £75,000-£120,000. Build time 14-18 weeks. Party wall agreements with both neighbours are required because the side return shares a boundary wall. Side return only extension on terraces with shallow rear gardens runs £35,000-£55,000. Build time 8-12 weeks. Less common in Battersea than rear-only or wraparound but useful where the rear garden is too short for a 4-metre rear projection.
Battersea-specific access and groundwater considerations
Two factors make Battersea kitchen extensions distinctive in cost and schedule. Access. The Victorian terraces between Clapham Junction and Battersea Park sit on tightly-packed streets, and many properties back onto railway lines, shared alleys, or other terraces. Materials delivery and waste removal can be involved. We do an access survey at the quote stage and price for the actual conditions: some streets need a smaller concrete pump (rather than the standard 30-metre boom), some need hand-carry of materials over short distances, and a few need scaffolding pavement licences from Wandsworth (£40-£80 per week). All of this is built into the fixed-price contract. Groundwater. Properties within 200-300 metres of the Thames may sit in Flood Zone 2 and need a Flood Risk Assessment as part of the planning application. The Environment Agency's flood risk maps confirm the zone. Cost of the assessment is typically £600-£1,200. Properties further from the river (around Northcote Road, Wandsworth Common borders) have standard clay subsoil and don't have these issues. Foundation depth on London Clay is typically 1.2-1.5 metres. Properties near mature trees on the larger streets may need 1.5-2.0 metre or piled foundations to avoid clay shrinkage from tree-root moisture extraction. The structural engineer specifies foundation depth based on a trial hole and tree survey.
Wandsworth process and standards
Battersea falls under Wandsworth Council, one of London's faster planning authorities. The standard 3-metre rear extension on terraces (or 4-metre on semis) is permitted development. We submit a Lawful Development Certificate (£103, 6-8 weeks at Wandsworth) for written confirmation, which protects the property at sale time. Larger extensions need full planning permission. Wandsworth typically determines applications in 8-10 weeks (faster than the 13-week statutory limit), and the council publishes design guidance that makes it straightforward to design within accepted parameters. For listed buildings (Grade II is most common in older Battersea), Listed Building Consent is required and runs in parallel with planning. All glazing is FENSA-registered with thermal performance to U-value 1.2-1.4 W/m²K. Electrical work is signed off under BS 7671 by our NICEIC-registered electrician. Plumbing and gas connections are signed off under Gas Safe regulations. Building Control inspections happen at foundation, drainage, structure, insulation, and completion stages, and the completion certificate is delivered at handover. Fixed-price contracts cover everything: labour, materials, structural engineer calculations, FENSA registration, planning fees, Building Control fees, party wall surveyor coordination, and any conservation area applications. The price doesn't change unless the specification does.

Frequently Asked Questions
- How much does a Battersea kitchen extension cost?
- Single-storey rear extensions of 4-5 metres run £55,000-£90,000 including structural steelwork, foundations, glazing, electrics, plumbing, and finishes. Wraparound extensions on the wider terraces run £75,000-£120,000. Side return only extensions run £35,000-£55,000. The 15-25% premium over outer London boroughs reflects deeper foundations on Battersea clay, premium specifications most clients choose, and tighter access on the SW11 terraced streets. We provide a fixed-price contract after the survey. The price doesn't change unless the specification does.
- Do I need a Flood Risk Assessment for a Battersea extension?
- Possibly, depending on flood zone designation. Properties within 200-300 metres of the Thames or in lower-lying parts of SW11 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. Cost is typically £600-£1,200 and we coordinate it as part of the planning process. Properties further from the river (around Northcote Road and Battersea Rise) are usually outside flood zones.
- How does access affect my Battersea extension cost?
- It depends on the property. Tightly-packed terraces, properties backing onto railway lines, and streets without rear access may need a smaller concrete pump, hand-carried materials, or pavement-mounted scaffolding licensed by Wandsworth (£40-£80 per week). We do an access survey at the quote stage and price for the actual conditions — some sites add a day or two to groundwork because of materials handling. All of this is built into the fixed-price contract before any work starts. There are no surprise extras mid-project.
