Victorian and Edwardian home transformations. RBKC planning checks.
Kensington's grand Victorian and Edwardian houses offer huge potential for loft conversions, rear extensions, and basement conversions. We navigate RBKC's conservation requirements so you don't have to.
Local project guide
Kensington projects range from whole-house refurbishments to apartments, mews houses and roof or basement work. We assess ownership, heritage constraints, structure, services and access together so the proposed layout can be built and approved without avoidable redesign.
Completed work
We haven't put a job on a W8 street on the site yet. The closest one is in Holland Park, W11, in the same Royal Borough.
About 1,700 sq ft. We restored the period character and fitted out the house with marble bathrooms, bespoke fitted wardrobes, gold-toned fittings and high-end finishes throughout.
In period houses like this, the original features are worth more than anything we could add, so protecting them comes first.
Holland Park is a conservation area with its own council appraisal, adopted in 2017, and that's what the planners measure external changes against. If you're thinking about a basement, RBKC's Local Plan normally limits new basements to one storey and half of each garden, and won't allow them under listed buildings. For flats, the freeholder's consent usually comes before the council's. Our Chelsea flat refurbishment is another job in the borough.

Typical project build prices, excluding VAT and professional fees (design, structural engineer, Building Control, party wall and planning fees). Prices are the same across every borough we cover; access and logistics (parking, skips, scaffold, restricted access) can affect the final price. Your fixed quote follows a site visit. Kensington's conservation areas may affect scope, so we check the planning position at our free site visit.
