Kitchen Extension Builders in Woolwich (SE18)
Professional kitchen extension builders in Woolwich, South East London.
Why Choose All Well for Kitchen Extensions in Woolwich?
Woolwich is changing fast, and the Victorian terraces behind the main road are where the character is. These houses are well-built but many haven't been updated in decades. A kitchen extension opens up the ground floor and brings the property into the 21st century: bifold doors, an island, proper lighting, and a room that connects to the garden. With the Elizabeth Line station nearby, an extension now gives you the space and quality of living the house was missing.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.
Kitchen Extensions for Woolwich Properties
Woolwich is known for its victorian terraces, new-build apartments, crossrail developments. Our kitchen extensions services are tailored to these property types, ensuring results that complement the character of your home.

Kitchen Extensions Tip for Woolwich Homeowners
Greenwich Council covers Woolwich. The Royal Arsenal conservation area has specific requirements, but most residential streets further from the river are outside it and standard permitted development applies. The Thames gravel subsoil in SE18 generally provides stable foundations, but properties on reclaimed land near the river may need additional ground investigation. If your property is near the Crossrail development, check whether any construction easements affect your rear garden before designing an extension.
Kitchen extension options for SE18 Victorian and Edwardian terraces
Three patterns cover most of what we build in Woolwich. The house type determines which one fits.
Single-storey rear extension on a Woolwich Victorian terrace
The Victorian terraces along Plumstead Road, Woolwich New Road, Herbert Road, and the streets behind the town centre are the most common SE18 project. These houses have a dark galley kitchen at the back, often with original cast-iron range fittings still behind layers of paint. We extend 3 to 4 metres into the rear garden, take out the load-bearing wall between the kitchen and dining room with a 152x89 UC steel beam, and finish with bifolds across the new rear elevation. Foundations on Woolwich's mixed Thames gravel and London Clay typically sit at 1.0 to 1.2 metres on standard sites, deeper on reclaimed land near the river. The price covers foundations, structural steel, glazing, electrics, plumbing, and finishes. Build time 10 to 14 weeks. Permitted development under Class A covers the standard 3-metre projection.
Wraparound and combined renovation-plus-extension projects in SE18
Edwardian terraces around Plumstead Common often have side returns of 1.0 to 1.4 metres, making a wraparound, side return infill combined with a rear projection, the right move. Build time 12 to 16 weeks. Party wall agreement with the neighbouring property is required. For owners who want the whole house brought up to standard at once, combining the kitchen extension with a full rewire, replumb, lead pipe replacement, and decoration into one coordinated project takes 4 to 8 weeks off the programme compared with running them as two separate phases. Combined projects run 16 to 22 weeks.
Flood risk, conservation areas, and ground conditions affecting Woolwich extensions
Three Woolwich-specific factors affect how a kitchen extension is designed. We check all three at the survey before quoting.
Thames flood risk, reclaimed land, and Royal Arsenal conservation requirements
Properties within 200 to 300 metres of the Thames, or in the lower-lying areas around the Royal Arsenal, may sit in Flood Zone 2 or 3 and need a Flood Risk Assessment as part of the planning application. Reclaimed land near the river can also have higher groundwater and looser fill. A trial hole at survey identifies the issue and the structural engineer specifies deeper foundations or short bored piles where standard strip foundations aren't suitable on affected sites. The Royal Arsenal conservation area covers the riverside development and surrounding streets. The Woolwich Town Centre conservation area covers parts of the high street and adjacent residential roads. Within both, exterior front-facing changes need sympathetic design and the Royal Borough of Greenwich can act on retrospective unauthorised changes. Most residential streets are outside both areas. Article 4 directions on some streets near the conservation area boundaries remove specific permitted development rights. We verify the planning status of each property on the Greenwich planning portal at the survey.
Royal Borough of Greenwich planning and project management for a Woolwich kitchen extension
Woolwich falls under the Royal Borough of Greenwich. Here is how the planning and build process works from survey to handover.
Permitted development and the Lawful Development Certificate in SE18
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 Article 4 directions apply or where the property is within a conservation area requiring full planning. The Larger Home Extension prior approval process covers 4 to 6 metre projections on terraces with an 8-week neighbour consultation. We submit a Lawful Development Certificate (£129, 6 to 8 weeks at Greenwich) on permitted development projects for written confirmation. This protects the property at sale time. Where the extension projects over a Thames Water public sewer, a Build Over Agreement is required plus a CCTV survey, and we handle the application.
Trades, inspections, and fixed-price contracts for Woolwich kitchen extensions
A Woolwich kitchen extension involves 12 to 15 trades over 10 to 16 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, and painting. 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. Origin or Schüco bifolds and Sieger sliders are common on Woolwich projects. Roof construction is warm-roof with 150mm PIR insulation. Underfloor heating across the new floor is standard. Fixed-price contracts cover labour, materials, structural engineer calculations for the steel and foundation design pack, Building Control fees, FENSA glazing registration, party wall surveyor coordination, conservation area applications where relevant, Flood Risk Assessment where applicable, and the Lawful Development Certificate or planning fee. The price is confirmed after a free site visit. One project manager from survey through handover with photo updates throughout the build.

Frequently Asked Questions
- How much does a Woolwich kitchen extension cost?
- It depends on the house and the work. Single-storey rear extensions of 3 to 4 metres on Victorian terraces are the most common Woolwich project, covering foundations, structural steel, glazing, electrics, plumbing, and finishes. Wraparound extensions suit wider Edwardian terraces. A combined kitchen extension plus full property renovation runs as a single coordinated project, which is faster than sequential delivery. Properties near the Thames may need a Flood Risk Assessment, reclaimed-land foundations near the river may need deeper foundations or short bored piles, and a Build Over Agreement with Thames Water applies where the extension crosses a public sewer. You get a fixed-price contract confirmed after a free site visit before any work starts.
- Do I need a Flood Risk Assessment for a Woolwich extension?
- For properties near the Thames, yes. Properties within 200 to 300 metres of the Thames or in the lower-lying areas around the Royal Arsenal 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 designation, and we check this at the survey before quoting. We coordinate it as part of the planning process. Reclaimed land near the river may also need additional ground investigation. A trial hole identifies the issue and the structural engineer specifies deeper foundations or short bored piles where standard strip foundations aren't suitable. Most residential streets behind the town centre are outside flood zones.
- Are there Article 4 directions in Woolwich?
- On some streets, particularly around the Royal Arsenal and Woolwich Town Centre conservation areas. Article 4 directions remove specific permitted development rights and require full planning permission for changes that would otherwise be permitted under Class A. They mainly affect front-of-property changes (cladding, window replacement, front-facing alterations) and rarely affect rear extensions, but where the direction covers rear-elevation changes, full planning permission applies and lead time extends from 6 to 8 weeks to 10 to 12 weeks at the Royal Borough of Greenwich. We verify the planning status of each property on the Greenwich planning portal at the survey before quoting.
- Why hire All Well for a Woolwich kitchen extension?
- Three reasons. First, accuracy: we know the SE18 stock, which streets sit in Flood Zone 2 or 3, where reclaimed land affects foundations, the Royal Arsenal and Woolwich Town Centre conservation areas, and how a combined renovation-plus-extension project comes together on these houses. Second, full accreditation: NICEIC for electrical (BS 7671), FENSA for glazing, Gas Safe registered for boiler relocation, structural engineer calculations included, and Building Control sign-off included on every project. Third, fixed-price contracts: the quote doesn't change unless the specification does, including Flood Risk Assessment, reclaimed-land foundation reassessment, party wall surveyor fees, and Build Over Agreement.
