The Holland Park and Pembridge conservation areas shape the west, where garden-square terraces are extended and converted under tight heritage and amenity controls. Whichever route your address falls under, we confirm it free at the measured survey and design to match the western Kensington and Chelsea streetscape — from period rear and side-return extensions to rear-dormer and mansard loft conversions.
