Planning and conservation in Camden
Planning and building control in this area are handled by Camden Council (London Borough of Camden). Much of Camden is in conservation areas and the borough has many listed buildings. Its local plan includes specific policies on basements and on design. 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.
Many Camden homes are flats, so planning permission is commonly needed even for modest extensions.
Typical building costs in Camden
As a central London borough, Camden typically sits in the central range of about £3,500 to £4,500+ per m² for residential work, a 25–40% premium over outer London. 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.

Yes. We work throughout Camden, including Hampstead, Kentish Town, Belsize Park, West Hampstead, Primrose Hill, Highgate, Tufnell Park, Swiss Cottage, and across the rest of London.
Do I need planning permission for an extension in Camden?
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 Camden Council (London Borough of Camden). A Lawful Development Certificate gives certainty.
