Kitchen Extension Builders in Greenwich (SE10, SE3)
Professional kitchen extension builders in Greenwich, South East London.
Why Choose All Well for Kitchen Extensions in Greenwich?
Greenwich has a real split personality when it comes to kitchen extensions. The Georgian terraces near the park need a conservation-sensitive approach — matching brickwork, traditional proportions, heritage-style glazing. But move a few streets towards Blackheath borders or Westcombe Park and you've got Victorian semis where you can build something more contemporary. We've worked on both types in SE10 and SE3, and knowing which approach each property needs is half the battle.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Greenwich Homeowners
The Royal Borough of Greenwich takes its heritage responsibilities seriously — understandably, given the UNESCO World Heritage Site. Properties near the park or in the town centre conservation area face stricter scrutiny, and the planning team expects high-quality materials and considered design. Further out, standard permitted development applies. We always confirm the conservation area boundaries at the start and design accordingly. Ground conditions near the river are variable, so a trial hole is essential before pricing foundations.
Three Greenwich kitchen extension patterns
Three patterns cover most of what we build in SE10 and SE3. Rear extension on a Victorian semi in SE3 is the most common Greenwich project. The Victorian semis along the Blackheath borders, the streets towards Westcombe Park, and the upper end of Maze Hill have wider plots than the Georgian terraces near the park. We extend 4-5 metres into the rear garden, take out the load-bearing wall between the kitchen and the dining room with a 178x102 UB or 203x133 UB steel beam, and finish with bifolds or sliders across the new rear elevation. Cost is £55,000-£90,000 including foundations on Greenwich's mixed gravel and clay subsoil (typically 1.0-1.4 metres depending on proximity to the river), structural steel, glazing, electrics, plumbing, and finishes. Build time 12-14 weeks. Conservation-sympathetic rear extension on a Georgian terrace is the second pattern, common in the streets near Greenwich Park, Maze Hill, and the Royal Hill area. The design brief is fundamentally different — traditional London stock brick to match existing, slate or natural-appearance roof material, timber sash windows or steel-frame Crittall-style glazing rather than aluminium bifolds. Cost is £70,000-£120,000 reflecting heritage materials. Build time 14-18 weeks. Full planning at £206 typically applies rather than permitted development; Listed Building Consent applies for the many Grade II listed Georgian properties. Riverside extension with flood resilience is the third pattern, common on properties within 200-300 metres of the Thames or on the Greenwich Peninsula. Cost is £60,000-£100,000 including foundations to suit the elevated water table, flood resilience measures (raised sockets, water-resistant materials below 600mm), and the Flood Risk Assessment. Build time 12-16 weeks. Properties further inland have standard requirements.
Maritime Heritage views, listed Georgian terraces, and Thames flood risk
Three Greenwich-specific factors affect kitchen extensions and add layers above standard Royal Borough of Greenwich planning process. Maritime Heritage views and the World Heritage Site buffer zone. Greenwich is a UNESCO World Heritage Site, and properties within the buffer zone face additional scrutiny on any development that could affect protected views — particularly views to and from the Royal Observatory, the Old Royal Naval College, and Greenwich Park. This rarely affects single-storey rear extensions because they don't break the existing roofline, but it shapes the council's expectations on materials and design. We design to the Royal Borough's published heritage guidance from the outset and use the council's pre-application advice service on borderline cases. Grade II and Grade II* listed Georgian terraces. Many of the Georgian terraces near Greenwich Park, Croom's Hill, and Maze Hill are Grade II or Grade II* listed and require Listed Building Consent for any extension or external alteration. Application takes 8-12 weeks at the Royal Borough and runs alongside planning. We work with conservation-specialist architects on listed projects and use heritage materials matched to the original — lime mortar pointing, traditional London stock brick, slate roofing, timber sash windows. Listed Greenwich extensions typically cost 30-50% more than equivalent work on a non-listed property. Thames flood risk. Properties within 200-300 metres of the Thames or on the Greenwich Peninsula may sit in Flood Zone 2 or 3 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. Some riverside properties also need flood resilience measures (raised electrical sockets at 600mm AFFL, water-resistant plasterboard and flooring below 600mm, flood barriers at door and air-brick openings) which add £2,000-£5,000 to extension cost.
Royal Borough of Greenwich process and project management
Greenwich falls under the Royal Borough of Greenwich, which has a dedicated conservation team that reviews applications within the Greenwich Town Centre, Blackheath, and other conservation areas individually. 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 conservation area Article 4 directions remove the right or where the property is listed. The Larger Home Extension prior approval process covers 4-6 metre projections on terraces and 4-8 metres on semis or detached. We submit a Lawful Development Certificate (£103, 6-8 weeks at Greenwich) on permitted development projects. Full planning at £206 applies on conservation area or larger projects. Listed Building Consent applies in addition on Grade II properties. A Greenwich kitchen extension involves 13-17 trades over 12-18 weeks: demolition, foundations and any flood resilience work, drainage, structural steel, brick and block (heritage matching where applicable), roofing, glazing, plastering (lime-based on listed properties), electrics (NICEIC to BS 7671), plumbing, gas (Gas Safe), kitchen fitting, tiling, flooring, painting, plus heritage trades on listed projects. 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), Building Control fees (£500-£800 at Greenwich), FENSA glazing registration, party wall surveyor coordination, conservation architect coordination on listed projects, Listed Building Consent fees, planning fees, Flood Risk Assessment, flood resilience measures where required, and Build Over Agreement where applicable. 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 typical on conservation projects; Sieger or IQ sliders on contemporary projects. Roof construction is warm-roof with 150mm PIR insulation.

Frequently Asked Questions
- How much does a Greenwich kitchen extension cost?
- Rear extensions of 4-5 metres on Victorian semis (the most common Greenwich project) run £55,000-£90,000 including foundations, structural steel, glazing, electrics, plumbing, and finishes. Conservation-sympathetic extensions on Georgian terraces near the park run £70,000-£120,000 reflecting heritage materials. Riverside extensions with flood resilience measures run £60,000-£100,000. Listed Building Consent on Grade II Georgian terraces typically adds 30-50% to construction cost. Flood Risk Assessment adds £600-£1,200. Build Over Agreement with Thames Water adds £317 plus CCTV survey. Conservation area planning applications add £206. Fixed-price contract before any work starts.
- Do I need Listed Building Consent for a Greenwich extension?
- If your property is Grade II or Grade II* listed, yes — common on the Georgian terraces near Greenwich Park, Croom's Hill, Maze Hill, and the Royal Hill area. Listed Building Consent applies to any alteration to a listed property, internal or external, and is separate from planning permission. Application takes 8-12 weeks at the Royal Borough of Greenwich, which has a dedicated conservation team. We work with conservation-specialist architects on listed projects and use heritage materials matched to the original — lime mortar, traditional London stock brick, slate roofing, timber sash windows. Listed Greenwich extensions typically cost 30-50% more than equivalent work on a non-listed property reflecting the heritage materials and the longer planning timeline.
- Do I need a Flood Risk Assessment for a Greenwich extension?
- For properties near the Thames, yes. Properties within 200-300 metres of the river or on the Greenwich Peninsula 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 at 600mm above finished floor level, water-resistant plasterboard and flooring below 600mm, flood barriers at doors and air bricks) which add £2,000-£5,000 to extension cost.
- Why hire All Well for a Greenwich kitchen extension?
- Three reasons. First, planning experience: we handle Listed Building Consent applications alongside Royal Borough of Greenwich planning on Grade II and Grade II* Georgian terraces, plus Flood Risk Assessment and World Heritage Site buffer zone considerations.
