Professional kitchen extension builders in Anerley, South East London.
Why Choose All Well for Kitchen Extensions in Anerley?
Anerley is our home borough. Our office is on Limes Avenue, SE20. We have completed more kitchen extensions in Anerley than any other area, and we know the housing stock inside out. The Victorian terraces along Anerley Road and the Edwardian semis around Anerley Hill both benefit from rear extensions that open up the ground floor into modern kitchen-diners.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Kitchen Extensions Tip for Anerley Homeowners
Anerley properties are under Bromley Council planning, and the area has no conservation zone restrictions. Permitted development rights are widely available for single-storey rear extensions up to 3 metres (terraced) or 4 metres (detached). The mixed clay and gravel subsoil in SE20 means foundation depths typically range from 1.0 to 1.3 metres. Being local, we can visit your property the same day you enquire.
Kitchen extension types we build in SE20 Anerley
Three patterns cover most of what we build in Anerley, and each suits a different housing type in SE20.
Rear extensions on Victorian terraces along Anerley Road and Anerley Park
The Victorian terraces running between Anerley and Penge stations almost always have a dark rear kitchen cut off from the dining room by a structural wall. We extend 3–4 metres into the rear garden, take out the internal wall with a slimline steel beam (typically 152x89 UC for the standard span), and finish with bifold or sliding doors across the back. Permitted development covers the 3-metre projection on terraces under Class A. Side return infill on the wider mid-Victorian terraces near Anerley Hill is the second pattern. A 0.9–1.2 metre return infills neatly with a glazed roof and a steel-framed structure tied into the existing party wall, requiring a party wall agreement with the neighbour.
Wraparound extensions on Edwardian semis around Anerley Hill
The Edwardian semis on the streets around Anerley Hill have larger plots and side access, which makes a wraparound the natural choice. Combining a 3-metre rear projection with a side return infill creates an open-plan kitchen-diner of 25–35 square metres. These semis were built around 1900–1910 with cavity walls, so insulation tie-in is straightforward. New cavity fill reaches U-value 0.18–0.21 W/m²K without losing floor area.
Bromley Council planning and SE20 ground conditions for kitchen extensions
Two Anerley-specific factors shape the technical and planning approach on every project here.
Permitted development and Lawful Development Certificates under Bromley Council
Anerley sits within Bromley Council's area and outside any conservation zone, so the standard Class A permitted development rules apply: 3-metre rear projection on a terrace, 4 metres on a semi, eaves to 3 metres, overall height to 4 metres. We submit a Lawful Development Certificate (£129 at Bromley, typically 6–8 weeks) on every project. This gives written confirmation of permitted development status and protects the property at sale or remortgage. Larger extensions of 4–6 metres on terraces go through the Larger Home Extension prior approval process; anything beyond that uses full planning. We handle the application as part of every project.
Foundation depths and party walls on Anerley terraces
SE20 sits on a transition between London Clay (lower ground towards Penge) and the river-terrace gravel running up the Crystal Palace ridge. Foundation depths typically run 1.0–1.2 metres on gravel and 1.2–1.5 metres on clay. We dig a trial hole at the survey on any project where ground conditions aren't already known from a nearby job, and the structural engineer specifies the design from that data. The design is firm before the contract is signed. The Victorian terraces along Anerley Road share 9-inch solid brick party walls, so most rear extensions trigger Party Wall Act 1996 notice requirements. We typically use an Agreed Surveyor where neighbours dissent, which keeps the process faster than each side appointing separately.
How we run an Anerley kitchen extension project, start to finish
A kitchen extension in SE20 typically involves 12–15 trades over 10–16 weeks. We assign one project manager from survey through handover who schedules the trades, manages materials, and sends photo updates throughout.
What's included in our fixed-price contract for SE20 kitchen extensions
Fixed-price contracts cover labour, materials, structural engineer calculations (for the steel design and pad-stone detail), Building Control fees at Bromley, FENSA glazing registration, party wall surveyor coordination, and the Lawful Development Certificate fee where permitted development applies. Where the extension passes over a public sewer, common on SE20 terrace rears, a Thames Water Build Over Agreement is required and we handle the application. Building Control inspects at foundation, DPC, drainage, structural steel, insulation (Part L: 0.18 W/m²K for new walls and roof), and completion stages. The completion certificate is handed over at the end. Our office on Limes Avenue is five minutes from any Anerley property, so same-day surveys are standard.

Frequently Asked Questions
- What's involved in an Anerley kitchen extension?
- Single-storey rear extensions of 3-4 metres on Victorian terraces are the most common Anerley project, covering foundations, structural steelwork, glazing, electrics, plumbing, and finishes. Side return infill suits the wider mid-Victorian terraces, and wraparound extensions work on Edwardian semis with side access. Where the extension passes over a public sewer, a Thames Water Build Over Agreement is required and we handle the application. Most rear extensions on the terraces trigger Party Wall Act notices, so we coordinate the surveyor where neighbours dissent. Everything is set out in a fixed-price contract confirmed after a free site visit, and the price doesn't change unless the specification does.
- How deep do foundations need to be on an Anerley kitchen extension?
- Typically 1.0-1.5 metres depending on subsoil. SE20 sits on a transition between London Clay (lower ground towards Penge) and the river-terrace gravel running up the Crystal Palace ridge. Gravel sites take 1.0-1.2 metres, clay sites take 1.2-1.5 metres under standard strip foundations. Properties near mature trees may need 1.5-2.0 metres or piled foundations to avoid clay shrinkage from root moisture extraction. We dig a trial hole at the survey on any new street, and the structural engineer specifies the foundation depth from the data. Building Control inspects the foundation trench before concrete is poured. The foundation design is firm before the contract is signed.
- Do I need planning permission for an Anerley kitchen extension?
- Most don't. Anerley is not in a conservation area and Bromley Council applies the standard Class A permitted development rules: 3-metre rear projection on a terrace, 4 metres on a semi, eaves up to 3 metres, overall height up to 4 metres. We submit a Lawful Development Certificate (£129, 6-8 weeks at Bromley) on every project for written confirmation of permitted development status. This protects the property at sale and avoids retrospective enforcement risk. Larger extensions of 4-6 metres on terraces (or up to 8 metres on semis) go through the Larger Home Extension prior approval process. Full planning covers anything beyond. We handle the application as part of every project.
