Premium construction and renovation in Central London — extensions, loft and basement conversions, kitchens, bathrooms and full refurbishments, managed end to end from our Harefield base.
Hangard Construction works across Central London from our base in Harefield, a straight run down the A40 and Westway into Westminster and Kensington & Chelsea. We are a main contractor for prime and commercial property, and most of what we do here falls into three areas: property maintenance for portfolio and private owners, basement conversions beneath townhouses and mansion blocks, and house extensions where the footprint and the planning regime allow. Almost every address we touch sits in a conservation area, is listed, or both, so we plan each job around consent from the outset.
We handle the planning side directly with the City of Westminster and RBKC, the strictest authorities in the country, including mandatory pre-application advice and listed-building consent. We are used to building in dense, high-footfall streets where access, working hours, hoarding and party-wall matters all have to be managed before a single tool comes out. The work is exacting and the standards are high, which suits the way we build.

We tailor every project to the homes, ground and planning context of Central London — here's what that means in practice.
What sets us apart in Central London isn't a sales pitch — it's knowing the homes, the ground and the planning here, and building accordingly.
With nearly every prime address listed or in a conservation area, we build the listed-building and conservation consent into the programme before we start, working pre-app with Westminster and RBKC.
We dig and underpin basements beneath townhouses and mansion blocks on London Clay and Thames gravels, the practical way to add space when the footprint cannot grow.
We manage access, restricted hours, hoarding and party-wall agreements on high-footfall streets where there is no room to spread out, the part suburban builders rarely have to plan for.
We restore stucco, sash windows, ornate plasterwork and slate and lead roofs to match the original, so protected facades pass the authorities and read as they always did.
