What local planning policy applies to a modern flat project in Kensington and Chelsea?
Conservation areas covering Kensington and Chelsea: RBKC Planning runs 38, and Notting Hill, Holland Park, Earls Court are the ones Kensington and Chelsea owners meet most. A modern flat project inside a Kensington and Chelsea conservation area loses permitted development, so the Kensington and Chelsea submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Kensington a modern flat project is judged on the street elevation first.
Kensington and Chelsea and Article 4: Article 4 Directions covering HMOs, office-to-residential, and basement developments — RBKC has some of the strictest basement policies in London. A modern flat project planned at a SW3 address is checked against that direction first; RBKC Planning publishes the Kensington and Chelsea extent, and the SW3 line rarely follows the Kensington and Chelsea boundary you would expect.
Kensington and Chelsea below-ground policy: RBKC's basement policy (post-2015) limits to single-storey under 50% of garden area; double-storey basements effectively prohibited in residential streets. Any modern flat project in Kensington and Chelsea that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and RBKC Planning will want the SW3 ground and groundwater position set out.
The building fabric around Kensington and Chelsea: Grand white stucco Regency and Victorian terraces; red-brick Queen Anne mansions in Kensington; Edwardian mansion blocks; almost no post-war housing stock.
