Planning and conservation in Lambeth
Planning and building control in this area are handled by Lambeth Council (London Borough of Lambeth). Lambeth has dozens of conservation areas and has published design guidance on building alterations, including extensions and roof works. Before you design, check whether your property is in a conservation area, is listed or is covered by an Article 4 direction; these change what you can build without permission. Our guide to permitted development in London explains the national rules, and loft conversion regulations covers roof works.
A detailed check of your street's conservation status is especially worthwhile in Lambeth.
Typical building costs in Lambeth
Costs in Lambeth usually sit between outer London rates (about £2,500 to £3,500 per m²) and central London rates (about £3,500 to £4,500+ per m²), depending on the street, access and specification. Budget on top for professional fees (about 15%), consents and contingency (8–15%) and VAT at 20% on extensions and renovations. These are indicative industry ranges for 2026, not a quote; see our London cost guide or request fixed quotes from local builders.

Questions about building in Lambeth
Can I request quotes from builders in Lambeth?
Yes. Quote requests are accepted from anywhere in Lambeth, including Brixton, Clapham, Kennington, Stockwell, Streatham, Herne Hill, West Norwood, Vauxhall, across London and the wider UK. With your consent, we pass your enquiry to up to 3 local builders who advertise with us.
Do I need planning permission for an extension in Lambeth?
It depends on your property. Houses outside conservation areas may be able to use permitted development, while flats, conservation areas and Article 4 directions usually mean an application to Lambeth Council (London Borough of Lambeth). A Lawful Development Certificate gives certainty.
Should I check a builder’s insurance?
We ask every builder who advertises with us to provide proof of current public liability insurance before they are listed. Always check each builder’s insurance, references, written quote and trade body membership yourself before work starts.
