This page covers the southern part of the borough — Chelsea, South Kensington, World's End and Brompton and the streets around them. The stock here is largely Georgian and Victorian terraces, garden-square houses and mansion flats, and we prepare drawings across every one of those types for RBKC Planning.
The south is heavily listed, with the Chelsea, Thurloe and Brompton conservation areas meaning most schemes need listed-building consent and are designed strictly to the period fabric — basements are a common but tightly-policed route to more space. Whichever route your address falls under, we confirm it free at the measured survey and design to match the southern Kensington and Chelsea streetscape — from period rear and side-return extensions to rear-dormer and mansard loft conversions.
