Side returns and rear kitchen extensions can transform narrow terrace layouts in Brixton, Clapham, Camberwell, Dulwich, Peckham and Balham.
1930s semis and detached homes
Wider plots in Croydon, Bromley and nearby southern suburbs often suit full-width rear extensions, larger kitchen islands and bigger garden openings.

Planning Permission, Permitted Development and Building Regulations
South London kitchen extensions need property-specific planning checks. Some single-storey rear and side projects may fall under permitted development, but conservation areas, flats, maisonettes, larger proposals and visible changes may need planning permission.
Useful official guidance: Planning Portal extension guidance, GOV.UK permitted development guidance, GOV.UK party wall guidance, Building Regulations approval guidance.
- When planning is needed: wraparound layouts, flats, maisonettes, conservation-area homes and larger or more visible proposals often need full planning permission.
- Party wall and neighbours: terraced and semi-detached homes often need party wall notices for excavation, shared walls or structural openings.
- Structural calculations: steel beams, RSJs, roof openings, knock-throughs and glazing require proper structural design and Building Control sign-off.
- Local context: Lambeth, Southwark, Wandsworth and Croydon projects can differ by conservation area, access, parking, drainage and original property type.

FAQs
Kitchen Extension FAQs
Do I need planning permission for a kitchen extension in South London?
Some kitchen extensions can be built under permitted development, but many projects need planning permission, especially wraparound extensions, flats, maisonettes, conservation-area homes and larger proposals.
Can I build a kitchen extension under permitted development?
Some single-storey rear and side extensions may qualify if they meet strict limits on size, height, boundaries, materials and previous extensions. A Lawful Development Certificate can help confirm the route.
How much does a kitchen extension cost in South London?
Many projects fall between £70,000 and £220,000+ depending on size, structure, access, glazing, drainage, kitchen specification, worktops and finish level.
What is the best kitchen extension for a Victorian terrace?
A side return or rear-and-side layout often works well because it adds width to the existing narrow kitchen and brings daylight through rooflights or a roof lantern.
Do I need a party wall agreement for a side return extension?
Many terraced and semi-detached homes need party wall notices where work affects shared walls, boundaries, excavation near neighbours or structural openings.
How long does a kitchen extension take from survey to completion?
The full process can take several months including survey, design, planning, structural calculations, party wall matters and construction. Site duration depends on size and specification.
Can I stay in my home while the extension is being built?
Often yes, but it depends on kitchen downtime, services, dust control, access, safety and whether temporary cooking arrangements are practical.
Do you handle design, structural calculations and Building Control?
Yes. We can help coordinate design drawings, structural calculations, Building Regulations information and Building Control requirements as part of the design and build route.
What South London areas do you cover?
We cover Brixton, Clapham, Dulwich, Peckham, Wandsworth, Croydon, Battersea, Balham, Streatham, Camberwell, Lewisham, Tooting, Wimbledon, Bromley and nearby areas.
