Building and renovation in SW3

Planning and consent in SW3
Kensington and Chelsea's conservation and basement policies are among the strictest in London: single-storey excavation, limited garden footprint and a construction traffic management plan are the norm. Listing is frequent along the historic riverside streets.
Access and site logistics
Narrow mews, permit-controlled streets, short loading windows and neighbours in close occupation. We agree hoarding, protection and working-hours arrangements with RBKC and adjoining owners before any demolition starts.
What we are usually asked for here
- Whole-house renovation and restoration of period Chelsea townhouses
- Basement excavation and lower-ground-floor conversion within RBKC policy
- Rear extensions, roof terraces and garden reconfiguration
- Luxury kitchen, bathroom and bespoke joinery installation
We survey the property before pricing, confirm the constraints that apply to your specific address rather than the postcode, and issue a fixed price against a written scope. One site manager runs the trades from first fix to snagging.
