What we know about building in Kensington & Chelsea
Housing stock
Stucco-fronted Victorian terraces, Georgian townhouses, mews houses, garden squares and lateral apartments in mansion blocks. Almost every street is in a conservation area and many buildings are listed.
Planning and permitted development
RBKC has more than 30 conservation areas and strict rules on roof extensions, rear closet-wing infills and basements (limited to one storey under the garden with a 50% garden retention rule). Expect full planning for most external work. We prepare design-and-access and heritage statements and liaise with the council's conservation officers.

- How long does a full refurbishment take in Kensington & Chelsea?
- A full refurbishment of a 150–200 m² townhouse, with structural changes, new services and bespoke joinery, typically takes 5–8 months on site. Listed building consent can add 8–12 weeks before work starts.
- Do you handle party wall agreements for terrace houses?
- Yes. Almost every project on a Kensington or Chelsea terrace needs party wall notices on both sides. We serve the notices and coordinate with the appointed surveyors so the programme is not delayed.
