Exclusive Builders in Notting Hill

A house, not a flat or maisonette, keeps national permitted development rights for a single-storey rear extension of 3m attached or 4m detached, up to 6m or 8m through prior approval, and most rear dormers within 40 or 50 cubic metres. Large parts of Notting Hill sit in the Royal Borough of Kensington and Chelsea's Ladbroke, Pembridge, Norland and Colville conservation areas, where side extensions, two-storey rear extensions, cladding and roof additions need permission. Article 4 directions on many Ladbroke, Pembridge and Norland streets control windows, front doors, boundary walls and roof coverings. Any basement needs permission under the borough-wide direction.

In the Royal Borough of Kensington and Chelsea, local Plan 2024 Policy CD11 limits a basement to one storey (exceptions only on large sites) under no more than 50 per cent of each garden, rules out adding a further floor to an existing basement and bars any excavation under a listed building, vaults included. At least one metre of soil is needed over any part under a garden. The Code of Construction Practice normally puts basement excavation in Category 1, with an approved Site Construction Management Plan, a Section 61 application and a Construction Bond. On the W2 edge, Westminster City Council's own policies apply instead.

Our London figures put a mansard loft conversion at £60,000–£100,000+ including VAT, with prime central schemes at £120,000–£150,000. On Notting Hill's stucco terraces the price follows the roof structure, the party walls and the detail the conservation area calls for, and some terraces will not take an extra storey at all. The mansard loft conversion cost guide sets out what each figure covers.

Notting Hill Villa, W11 is in Notting Hill itself, about 0.1 miles from the centre: every lead valley on a period villa roof was renewed and the basement store waterproofed and reinstated. Hammersmith Terrace, W6, about 1.6 miles away, was a terraced house reworked from the lower ground floor to a new loft floor, with a new steel frame and a full refit. Golders Green 1930s Semi, NW11, about 4.6 miles away, was a rear extension, two-storey side extension and full renovation of a 1930s semi-detached house.

We cover Notting Hill in W11, including Ladbroke Grove, Elgin Crescent, the communal garden squares, the mews houses and the terraces towards Westbourne Grove and Golborne Road. Most of the area is in the Royal Borough of Kensington and Chelsea, while the eastern edge in W2 comes under Westminster City Council. We work from South Woodford, E18, about 12 miles away, and also cover Kensington, Shepherd's Bush and Hammersmith.
