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 we finalise foundations.
Kitchen extension types we build in SE10 and SE3
Three patterns cover most of what we build across Greenwich. Which one applies to your property depends on the street, the housing type, and how close you are to the river.
Victorian semi kitchen extensions near Blackheath and Westcombe Park
Rear extension on a Victorian semi is the most common Greenwich project. The 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 kitchen and dining room with a 178x102 UB or 203x133 UB steel beam, and finish with bifolds or sliders across the new rear elevation. Foundations sit on Greenwich's mixed gravel and clay subsoil, typically 1.0-1.4 metres deep depending on proximity to the river, with structural steel, glazing, electrics, plumbing, and finishes all part of the package. Build time 12-14 weeks.
Heritage kitchen extensions on listed Georgian terraces near Greenwich Park
The streets near Greenwich Park, Maze Hill, and the Royal Hill area are a different brief entirely. 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. Heritage materials and traditional detailing run right through the build. Build time 14-18 weeks. Full planning typically applies rather than permitted development; Listed Building Consent is also required for the many Grade II listed Georgian properties in these streets. Riverside extensions on SE10 properties within 200-300 metres of the Thames or on the Greenwich Peninsula need foundations suited to the elevated water table, flood resilience measures (raised sockets, water-resistant materials below 600mm), and a Flood Risk Assessment. Build time 12-16 weeks.
Greenwich-specific planning factors: heritage, listed buildings, and flood risk
Three factors specific to Greenwich sit on top of the standard Royal Borough of Greenwich planning process. All three can shape the design and the programme, so we check all of them at the survey stage before we quote.
UNESCO World Heritage Site buffer zone and Royal Borough design expectations
Greenwich is a UNESCO World Heritage Site, and properties within the buffer zone face additional scrutiny on anything that could affect protected views, particularly views to and from the Royal Observatory, the Old Royal Naval College, and Greenwich Park. Single-storey rear extensions rarely affect those views directly, but the Royal Borough's conservation team still expects high-quality materials and considered design across the whole town centre and park-edge conservation areas. We design to the Royal Borough's published heritage guidance from the outset and use the pre-application advice service on borderline cases.
Listed Building Consent and Thames flood risk in SE10
Many of the Georgian terraces near Greenwich Park, Croom's Hill, and Maze Hill are Grade II or Grade II* listed and need Listed Building Consent for any extension or external alteration. That runs alongside planning at the Royal Borough and takes 8-12 weeks. 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 ask for finer materials and craftsmanship than equivalent work on an unlisted property, and the planning timeline is longer. For riverside properties, the Environment Agency's flood risk maps confirm whether a property sits in Flood Zone 2 or 3. A Flood Risk Assessment is required as part of the planning application. Some riverside properties also need flood resilience measures: raised electrical sockets at 600mm AFFL, water-resistant plasterboard and flooring below 600mm, and flood barriers at door and air-brick openings.
Royal Borough of Greenwich planning and build process for kitchen extensions
The Royal Borough has a dedicated conservation team that reviews applications within the Greenwich Town Centre, Blackheath, and other conservation areas individually. Knowing which rules apply before the design is fixed saves time later.
Permitted development, prior approval, and Lawful Development Certificates in Greenwich
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 that 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 (£129, 6-8 weeks at the Royal Borough of Greenwich) on permitted development projects. Full planning 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. We assign one project manager from survey through handover, with photo updates throughout the build. The contract price is fixed and confirmed after a free site visit, covering labour, materials, structural engineer calculations, Building Control fees, FENSA glazing registration, party wall surveyor coordination, conservation architect coordination on listed projects, Listed Building Consent, planning, Flood Risk Assessment, flood resilience measures where required, and a Build Over Agreement where applicable. Building Control inspections run at foundation, DPC, drainage, structural steel, insulation (Part L: U-value 0.18 W/m²K), and completion.

Frequently Asked Questions
- What is involved in a Greenwich kitchen extension?
- Rear extensions of 4-5 metres on Victorian semis are the most common Greenwich project, including foundations, structural steel, glazing, electrics, plumbing, and finishes. Conservation-sympathetic extensions on Georgian terraces near the park use heritage materials throughout. Riverside extensions add flood resilience measures. Listed Building Consent on Grade II Georgian terraces calls for finer heritage materials and a longer planning timeline. A Flood Risk Assessment and, near the Thames, a Build Over Agreement with Thames Water plus a CCTV survey may also apply, along with conservation area planning. The contract price is fixed and confirmed after a free site visit.
- 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 call for finer materials and craftsmanship than equivalent work on a non-listed property, and the planning timeline is longer.
- 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. 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, and flood barriers at doors and air bricks.
