Planning and conservation in Wandsworth
Planning and building control in this area are handled by Wandsworth Council. The borough has many conservation areas, and areas near the Thames and the River Wandle may have flood-risk considerations. 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.
Wandsworth and Richmond share a planning service, so guidance often looks similar across the two boroughs.
Typical building costs in Wandsworth
Costs in Wandsworth 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.

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 Wandsworth Council. A Lawful Development Certificate gives certainty.
