Kitchen Extension Builders in Putney (SW15)
Professional kitchen extension builders in Putney, South West London.

Why Choose All Well for Kitchen Extensions in Putney?
Putney's Edwardian and Victorian houses tend to be larger than the terraces in Battersea or Clapham, with wider plots and deeper gardens. That means we can build more ambitious extensions — 5-6 metre rear extensions with full-width glazing are common here. The properties around Putney Heath and the Upper Richmond Road are particularly well-suited, with enough space for a wraparound that creates a kitchen, dining area, and garden room in one flowing space.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Putney Homeowners
Putney has some streets with covenants restricting development, particularly on the older estates near the river. We check the title deeds during the free consultation to flag any restrictions before you commit. Properties closer to the Thames may fall in Flood Zone 2 — this doesn't prevent an extension but does require a Flood Risk Assessment (around £300-£500) as part of any planning application. Wandsworth Council handles Putney and their planning process is straightforward.
Three Putney kitchen extension patterns
Three patterns cover most of what we build in SW15. Deep rear extension on an Edwardian house is the most common Putney project. The Edwardian houses along Upper Richmond Road, Charlwood Road, and the streets running off Putney Hill have wider plots and deeper rear gardens than typical inner London terraces. We extend 5-6 metres into the rear garden, take out the load-bearing wall between the kitchen and the dining room with a 203x133 UB or 254x146 UB steel beam, and finish with full-width sliders or bifolds across the new rear elevation. Cost is £65,000-£100,000 including foundations on Putney's mixed clay and gravel (typically 1.0-1.5 metres), structural steel, glazing, electrics, plumbing, and finishes. Build time 14-16 weeks. The 5-6 metre projection on a semi or detached typically goes through the Larger Home Extension prior approval process. Wraparound extension on a wider Edwardian or Victorian property is the second pattern, common around Putney Heath and the streets towards Wimbledon Common. Combines a side return infill with a 4-5 metre rear projection. Creates 35-50 square metres of new open-plan space. Cost is £80,000-£130,000. Build time 14-18 weeks. Mansion flat kitchen renovation with internal alterations is the third pattern, common in the Edwardian mansion blocks near Putney Bridge. These flats can't extend physically but typically need internal layout reconfiguration to merge a separate kitchen and reception into an open-plan space. Cost is £30,000-£60,000 depending on scope and scale of structural opening-up. Build time 8-12 weeks. Section 20 leaseholder consultation with the freeholder applies — we coordinate the consultation as part of the project.
Putney mansion blocks, Thames floodplain, and freeholder Section 20
Three Putney-specific factors affect kitchen projects and add layers above the standard Wandsworth process. Mansion flats and Section 20 consultation. Putney has a high concentration of Edwardian mansion blocks, particularly around Putney Bridge, Lower Richmond Road, and the streets towards Putney Heath. Internal alterations to mansion flats trigger Section 20 leaseholder consultation requirements where the works exceed cost thresholds set by the Landlord and Tenant Act 1985 and the freeholder's right to be consulted on major works applies. Most mansion block leases also include a Licence to Alter requirement for any structural change — opening up an internal load-bearing wall always counts. Application to the freeholder takes 4-12 weeks depending on the management company and structural engineer's calculations are required for the licence application. We coordinate the application and licence as part of the project. Thames floodplain. Putney properties within 200-300 metres of the Thames 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. 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. Properties further from the river (around Putney Heath and the upper streets) are usually outside flood zones. Wandsworth Common conservation area and Article 4. Parts of Putney near Wandsworth Common fall within the Wandsworth Common conservation area and parts of upper Putney are within Article 4 directions. Within both, exterior front-facing changes need sympathetic design and Wandsworth Council can act on retrospective unauthorised changes. Rear extensions are generally fine because they're not visible from the street. We check the boundary on the Wandsworth planning portal at the survey before quoting.
Wandsworth Council process and project management
Putney falls under Wandsworth Council, which is regarded as one of London's faster planning authorities. Permitted development under Class A covers the standard 3-metre rear projection on a terrace and 4 metres on a semi or detached. 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. Wandsworth typically determines applications in 8-10 weeks (faster than the 13-week statutory limit). We submit a Lawful Development Certificate (£103, 6-8 weeks at Wandsworth) on permitted development projects for written confirmation, which protects the property at sale time. A Putney kitchen extension involves 13-17 trades over 12-18 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. Mansion flat projects involve a similar trade list within an 8-12 week programme. We assign one project manager from survey through handover with photo updates throughout the build. Fixed-price contracts cover labour, materials, structural engineer calculations (£700-£1,500 for the steel and foundation design pack including any mansion-block licence calculations), Building Control fees (£400-£700 at Wandsworth), FENSA glazing registration, party wall surveyor coordination, Section 20 leaseholder consultation and Licence to Alter coordination on mansion flats, conservation area applications where relevant, Flood Risk Assessment where applicable, and the 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. Crittall-style steel-frame doors and Sieger or IQ sliders are common on Putney projects. 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 Putney kitchen extension cost?
- Deep rear extensions of 5-6 metres on Edwardian houses (the most common Putney project) run £65,000-£100,000 including foundations, structural steel, full-width glazing, electrics, plumbing, and finishes. Wraparound extensions on wider properties run £80,000-£130,000. Mansion flat kitchen renovations with internal load-bearing wall removal run £30,000-£60,000.

Fixed-price contract before any work starts.
- Do I need freeholder consent for a kitchen alteration in a Putney mansion flat?
- Almost always yes. Most Putney mansion block leases include a Licence to Alter requirement for any structural change, which opening up an internal load-bearing wall counts as. Where the works exceed cost thresholds set by the Landlord and Tenant Act 1985, Section 20 leaseholder consultation also applies — the freeholder must be given the opportunity to consult other leaseholders before major works proceed. Application to the freeholder takes 4-12 weeks depending on the management company and structural engineer's calculations are required for the licence. We coordinate the application and licence as part of the project, including liaising with the freeholder's surveyor where the freeholder requires their own structural review.
- Do I need a Flood Risk Assessment for a Putney extension?
- Possibly, depending on flood zone designation. Properties within 200-300 metres of the Thames 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. Properties further from the river (around Putney Heath and the upper streets) are usually outside flood zones.
