Kitchen Extension Builders in Fulham (SW6)
Professional kitchen extension builders in Fulham, South West London.
Why Choose All Well for Kitchen Extensions in Fulham?
Fulham kitchens are where we bring out the premium specifications. The Victorian terraces along Munster Road, Bishops Road, and towards Parsons Green have period proportions that deserve an extension to match — proper steelwork, high-quality glazing, underfloor heating, and a kitchen that's designed rather than just fitted. Property values in SW6 justify the investment, and a well-executed kitchen extension in Fulham adds comfortably more than it costs. We've built extensions here ranging from compact side returns to full wraparounds.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Fulham Homeowners
Hammersmith and Fulham Council has extensive conservation areas across Fulham, and the planning team is particular about design quality. Extensions in conservation areas need to use materials that match or complement the existing house — stock brick, timber or Crittall-style glazing, natural slate or lead roofing. Outside conservation areas, standard permitted development is available. Fulham's London Clay subsoil requires foundations of 1.2-1.5 metres, and properties near mature trees along the Fulham Palace Road may need deeper piled foundations.
Three Fulham kitchen extension patterns
Three patterns cover most of what we build in SW6. Wraparound extensions are the flagship Fulham project. The Victorian terraces along Munster Road, Bishops Road, and the streets towards Bishops Park have generous side returns and deep rear gardens that suit combined side-and-rear wraparound extensions of 25-40 square metres. Typical specification includes Crittall-style glazing, roof lanterns, underfloor heating, and a high-end kitchen from a specialist supplier. Cost is £85,000-£150,000 including structural steelwork, foundations on Fulham clay (typically 1.2-1.5 metres), glazing, electrics, plumbing, and finishes. Build time 14-18 weeks. Rear-only extensions of 3-4 metres are common on the tighter terraces near Fulham Broadway and the streets towards Parsons Green. Cost is £55,000-£90,000. Build time 12-14 weeks. Hammersmith and Fulham's permitted development process covers the standard 3-metre rear extension on terraces. Side return only extensions on properties with deep rear gardens but narrow plots run £40,000-£65,000. Build time 10-12 weeks. Party wall agreements with the neighbouring property are required because the side return shares a boundary wall. Fulham property values mean kitchen extensions deliver some of the strongest ROI in London. A well-executed wraparound typically returns 1.4-1.8× build cost in property value uplift, which is why so many SW6 owners extend rather than move.
Premium specification standards on Fulham extensions
Fulham clients typically specify the premium end of every component, and we're set up for that. Glazing is usually steel-framed Crittall-style with thermally broken frames and double or triple glazing (U-value 1.2-1.4 W/m²K), supplied by Crittall, Fabco Sanctuary, or Industrial Sashes. Roof lanterns are from Atlas, Lonsdale, or Vitral. We're FENSA-registered for installer compliance and the registration is included in every project. Kitchen units come from a bespoke joinery supplier, often customised to fit precisely with the extension geometry. Worktops are typically natural stone (Calacatta, Carrara, or Statuario marble; Caesarstone or Silestone for engineered alternatives). Appliances are usually integrated and from premium suppliers (Sub-Zero, Wolf, Gaggenau, Miele). Underfloor heating is standard, fitted to the new extension and often retrofitted to the existing kitchen and dining areas during the same project. The system is designed to BS EN 1264 standards. Electrics are signed off under BS 7671 17th Edition by our NICEIC-registered electrician. Plumbing and gas connections are signed off under Gas Safe regulations. Building Control inspections at structure, insulation, and completion are included, and the completion certificate is delivered at handover. Fixed-price contracts cover everything: labour, materials, structural engineer calculations, FENSA registration, Building Control fees, planning fees, and any conservation area or Listed Building Consent applications. The price doesn't change unless the specification does.
Hammersmith and Fulham planning and practical considerations
Fulham falls under Hammersmith and Fulham Council, which has extensive conservation areas across the borough — Fulham Park Gardens, Studdridge Street, Hurlingham, and several others. Within these areas, exterior alterations need to use materials that match or complement the existing house: stock brick, timber or Crittall-style glazing, natural slate or lead roofing. Front-facing changes are virtually never approved; rear extensions are usually approved with appropriate materials. We design to the council's published guidelines from the outset, and our submitted designs typically get approved without revisions. The London Clay subsoil in SW6 requires foundations of 1.2-1.5 metres. Properties near mature trees on Fulham Palace Road or in the larger gardens may need deeper foundations of 1.5-2.0 metres or piled foundations. The structural engineer's foundation specification is firm before we issue the contract. 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 for a new extension. The Environment Agency's flood risk maps confirm the zone designation. Cost of the assessment is typically £600-£1,200 and we coordinate it as part of the planning process. Many Fulham Victorian terraces have rear additions (kitchens, sculleries, outhouses) that were built in stages from the 1880s onwards. These additions are often poorly built compared with the main house and have inadequate foundations or single-skin walls. When extending, we typically remove the existing addition and rebuild as a single coherent extension with proper foundations and structural integrity. Costs more than building onto the existing addition but produces a significantly better long-term result.

Frequently Asked Questions
- How much does a Fulham kitchen extension cost?
- Wraparound extensions (the most common Fulham project) run £85,000-£150,000 including structural steelwork, foundations on London Clay, premium glazing, electrics, plumbing, and finishes. Rear-only extensions of 3-4 metres run £55,000-£90,000. Side return only extensions run £40,000-£65,000. The 20-30% cost premium over outer London boroughs reflects deeper foundations, premium specifications, and the local trade rates. A well-executed Fulham kitchen extension typically returns 1.4-1.8× cost in property value uplift, among the strongest ROI in London.
- What materials does Hammersmith and Fulham accept in conservation areas?
- Materials that match or complement the existing house: stock brick, timber or Crittall-style steel-framed glazing, natural slate or lead roofing. Synthetic alternatives (uPVC windows, concrete tiles, render-on-block) are typically refused on visible elevations. Front-facing changes need particularly careful design — Hammersmith and Fulham's planning team is particular about proportions, materials, and sympathetic style. Rear extensions and side returns are usually approved with appropriate materials. We design to the council's published guidelines from the outset and our submitted designs typically get approved without revisions.
- How deep are Fulham foundations?
- Typically 1.2-1.5 metres for standard sites, deeper near mature trees. The London Clay subsoil shrinks and swells with moisture, and proximity to mature trees (Fulham Palace Road plane trees, large suburban gardens) means clay shrinkage from tree-root moisture extraction. Properties within 1-1.5 times tree height often need foundations of 1.5-2.0 metres or piled foundations. Properties within 200-300 metres of the Thames may also need a Flood Risk Assessment. The structural engineer's foundation specification is firm before we issue the contract — we don't add margin or pass cost overruns to the client.
- Why choose All Well for a Fulham kitchen extension?
- Three reasons. First, accuracy: projects across 25 London boroughs since 2020 means we price Fulham extensions accurately, including the foundation premiums and conservation area design requirements. Second, full accreditation: NICEIC electrical (BS 7671), FENSA glazing, Gas Safe boiler work, structural engineer calculations, and Building Control sign-off included on every project. Third, fixed-price contracts: the quote doesn't change unless the specification does, and we absorb our own surprises rather than passing them on. 57 verified Google reviews averaging 4.5/5.
