Kitchen Extension Builders in Camberwell (SE5)
Professional kitchen extension builders in Camberwell, South East London.
Why Choose All Well for Kitchen Extensions in Camberwell?
Camberwell's Victorian terraces and Georgian houses make for some of the most characterful kitchen extension projects in South East London. The challenge, and the reward, is creating a modern open-plan kitchen that respects the period architecture. We build extensions that flow naturally from the original house, using materials and proportions that complement rather than clash with what's already there. The result is a kitchen that feels like it was always part of the house.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Camberwell Homeowners
Camberwell has several conservation areas managed by Southwark Council: Camberwell Grove, Camberwell Green, and Sceaux Gardens. Extensions in these areas need to follow specific design guidelines around materials, roof forms, and boundary treatment. If your property is on Camberwell Grove or Grove Lane, there's a good chance it's Grade II listed, which means Listed Building Consent is required for any alteration. We work with a conservation-specialist architect for listed property extensions.
Kitchen extension types that work for SE5 terraces and villas
Three patterns cover most of what we build in Camberwell. Which one fits your property depends on plot width, proximity to the conservation area boundary, and how your rear garden sits relative to the existing kitchen.
Side return and wraparound options on Camberwell Victorian terraces
Side return infill is the most common SE5 project. The Victorian terraces around Denmark Hill, Champion Hill, and the streets running off Camberwell Church Street typically have side returns of 1.0–1.4 metres that infill with a glazed roof and steel-framed structure. Combined with knocking through the existing kitchen wall, the side return creates a wider open-plan kitchen-diner without giving up rear garden space. The build covers the structural roof, party wall foundations on Camberwell clay, glazing, electrics, plumbing, and finishes. Build time 8–12 weeks. Party wall agreement with the neighbouring property is required. Wraparound extension on a Victorian villa is the second pattern, common on the wider plots between Camberwell Green and Champion Hill. It combines a side return infill with a 4–5 metre rear projection, creating 30–40 square metres of new open-plan space. Build time 14–18 weeks. Where the property sits within the Camberwell Grove, Camberwell Green, or Sceaux Gardens conservation area, full planning typically applies rather than permitted development.
Single-storey rear kitchen extension on a narrower SE5 terrace
Single-storey rear extension is the third pattern, covering foundations, steel, glazing, and finishes. Build time 12–14 weeks. Permitted development under Class A covers the standard 3-metre projection where conservation area Article 4 directions don't apply on the Southwark side.
Listed buildings, conservation areas, and tree-affected foundations in Camberwell SE5
Three Camberwell-specific factors add planning layers above the standard Southwark process: Grade II listings on Camberwell Grove, the three main conservation areas, and the mature trees along Camberwell Grove that draw moisture from London Clay.
Grade II listed properties on Camberwell Grove and Grove Lane: what consent is needed
Many of the Georgian and early Victorian properties along Camberwell Grove and Grove Lane are Grade II listed and require Listed Building Consent for any extension or external alteration. Listed Building Consent is separate from planning permission and applies whether the proposed change is internal or external. Application takes 8–12 weeks at Southwark Council and runs alongside planning. We work with conservation-specialist architects on listed projects and use heritage materials matched to the original: typically lime mortar pointing, traditional stock brick, slate roofs, and timber sash window matching. Listed work uses heritage materials and conservation detailing throughout, which means a higher specification than equivalent work on a non-listed property.
Camberwell Grove, Camberwell Green, and Sceaux Gardens conservation area rules
Three main residential conservation areas cover a significant portion of SE5. Within all three, Southwark Council reviews exterior alterations individually. Rear extensions need sympathetic materials: typically traditional London stock brick to match the existing, slate or natural-appearance roof material, and timber or steel-frame fenestration rather than uPVC. Front-facing changes are virtually never approved. We check the conservation area boundary on the Southwark planning portal at the survey before quoting. Crittall-style steel-frame doors are standard on conservation area projects to match the period character. Mature plane trees and limes along Camberwell Grove and Grove Lane extract significant moisture from the London Clay subsoil during dry weather, causing clay shrinkage that can trigger subsidence on properties within 1–1.5 times tree height. Standard 1.0–1.2 metre strip foundations aren't enough. The typical specification is 1.5–2.0 metres of trench-fill or short bored piles. Tree Preservation Orders are common and removing trees for an extension is rarely permitted.
Southwark Council process and project management for a Camberwell kitchen extension
Camberwell falls under Southwark Council, which has a dedicated conservation team reviewing applications within the Camberwell Grove, Camberwell Green, and Sceaux Gardens 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. We submit a Lawful Development Certificate (£129, 6–8 weeks at Southwark) on permitted development projects for written confirmation, which protects the property at sale time. Full planning applies on conservation area or larger projects. Listed Building Consent applies in addition to planning on Grade II properties.
Trades, timeline, and what a fixed-price contract covers in SE5
A Camberwell kitchen extension involves 13–17 trades over 12–18 weeks: demolition, foundations and any piling, 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 (including tree-affected foundation design), Building Control fees at Southwark, FENSA glazing registration, party wall surveyor coordination, conservation architect coordination on listed projects, Listed Building Consent fees, planning fees, trial hole investigation, and Build Over Agreement where the extension passes over a public sewer. 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. Where the existing rear wall is original lime plaster, breathable plaster repairs (BS EN 459 Air Lime) and breathable mineral paint are used rather than gypsum to avoid trapping moisture in the wall.

Frequently Asked Questions
- What's involved in a Camberwell kitchen extension?
- Side return infill on a Victorian terrace is the most common Camberwell project, covering foundations, structural roof, glazing, and finishes. Wraparound extensions suit Victorian villas with wider plots. Single-storey rear extensions work on narrower terraces. Listed Building Consent on Grade II properties along Camberwell Grove brings heritage materials into the spec (lime mortar, slate roofs, timber sash matching) and conservation architect coordination. Foundations near the mature trees on Camberwell Grove go deeper than standard to stay clear of the active root zone in London Clay. Conservation area work needs a full planning application. We confirm a fixed price after a free site visit before any work starts.
- Do I need Listed Building Consent for a Camberwell extension?
- If your property is Grade II listed, yes. This is common on Camberwell Grove, Grove Lane, and parts of Camberwell Green. 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 Southwark Council, which has a dedicated conservation team that reviews these applications individually. The application runs alongside planning where external work is involved. 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 work carries a higher specification than equivalent work on a non-listed property because of the heritage materials and detailing involved.
- Why do mature trees on Camberwell Grove affect foundation depth?
- Because they extract moisture from London Clay during dry weather. The mature plane trees and limes along Camberwell Grove and Grove Lane draw significant moisture from the clay subsoil, causing clay shrinkage that triggers subsidence on properties within 1-1.5 times tree height. Standard 1.0-1.2 metre strip foundations to Building Regulations Part A don't reach stable bearing strata below the tree's active root zone. The structural engineer specifies foundation depth from a trial hole and tree survey, typically 1.5-2.0 metres of trench-fill or short bored piles. Tree Preservation Orders are common across the area and removing trees is rarely permitted by Southwark Council.
- Why hire All Well for a Camberwell kitchen extension?

First, planning experience: we handle Listed Building Consent applications alongside Southwark planning on Grade II Camberwell Grove properties, and we know what Southwark's conservation team accepts in the Camberwell Grove, Camberwell Green, and Sceaux Gardens conservation areas.
