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 a fixed quote.
