Premium construction and renovation in Knightsbridge — extensions, loft and basement conversions, kitchens, bathrooms and full refurbishments, managed end to end from our Harefield base.
Knightsbridge sits on the Westminster and RBKC border, where grand Victorian mansion blocks, stucco terraces and ultra-prime townhouses set the standard for almost every job we take on here. We work from our Harefield base, a straightforward run down into prime central London, which lets us hold a steady, properly supervised presence on streets where access, hours and neighbour management matter as much as the build itself. Most of what we are asked to do here falls into three areas: ongoing property maintenance for owners and managing agents, basement conversions, and loft conversions that respect a protected roofline.
Building in Knightsbridge means working inside two overlapping planning regimes and a made neighbourhood plan, so we treat consent as part of the craft rather than an afterthought. We handle the planning, listed-building and conservation-area applications with Westminster and RBKC, and we expect the pre-application engagement these boroughs ask for. From lateral conversions across mansion-block flats to deep basements and discreet roof additions, the brief is the same: a quiet site, a clean finish, and a frontage left exactly as the conservation area intends.

We tailor every project to the homes, ground and planning context of Knightsbridge — here's what that means in practice.
What sets us apart in Knightsbridge isn't a sales pitch — it's knowing the homes, the ground and the planning here, and building accordingly.
We combine adjacent prime flats into single residences and handle the structural, acoustic and party-wall work that shared mansion-block construction demands.
We manage applications across the Westminster and RBKC boundary and the Knightsbridge Neighbourhood Plan, with the pre-application engagement these authorities expect.
We build deep basements and leisure additions beneath townhouses founded on London Clay and Thames terrace gravels, with the underpinning and waterproofing that ground requires.
We run ongoing maintenance that accounts for Knightsbridge's very hard water, protecting high-end M&E and fittings from the limescale that shortens their life.
