Planning and conservation in Richmond upon Thames
Planning and building control in this area are handled by Richmond Council (London Borough of Richmond upon Thames). The borough has a large number of conservation areas, Metropolitan Open Land and parkland, and parts of the riverside are in flood zones, which can affect extensions and basements. 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.
Flood-risk assessments are commonly requested for projects near the Thames.

These are indicative industry ranges for 2026, not a quote; see our London cost guide or request fixed quotes from local builders.
