Knightsbridge projects demand foundations that are accurate, compliant and discreetly delivered. Whether you’re extending near Harrods or upgrading a property close to Hyde Park, we create stable bases that suit the structure above. From strip foundations to reinforced wall footings, our team handles excavation, steel placement and concrete pours with tight tolerances. Every job is planned around access, neighbours and the finish expected in SW1 and SW3.
Local properties include grand mansion blocks, period townhouses and ultra-luxury apartments, often with complex load paths and limited working space. In Belgravia and South Kensington, we frequently see party-wall considerations, older brickwork and mixed ground conditions that benefit from engineered solutions. For heavier structures or deeper digs, we specify deep foundations and reinforcement to control settlement. Our approach keeps the build stable without over-digging or unnecessary disruption.
We start with a site visit, levels, and an engineering-led recommendation for strip, pad, raft or deep foundations. You’ll get clear method statements, Building Regs-aligned detailing, and careful coordination for deliveries and spoil removal. We protect finishes, keep the site tidy, and communicate daily so you always know what’s happening. Homeowners choose us for concrete foundations knightsbridge area work that’s properly reinforced, inspected and guaranteed.
Work in the concrete foundations in Royal Borough of Kensington and Chelsea/City of Westminster zone often involves restricted access, controlled parking, and strict noise and working-hour expectations. Mansion blocks and townhouses can require staged pours, smaller wagons, and pump planning. We adapt to local ground variability and nearby structures with reinforced solutions and careful sequencing. If permits or suspensions are needed, we help you plan them early to avoid delays.
Rated 4.9/5 from over 280 verified reviews
Costs vary with foundation type, depth, access and spoil disposal. As a guide, smaller strip foundations for a modest extension might start around £3,000–£7,000, while larger or reinforced schemes can be £8,000–£20,000+. Raft foundations commonly sit higher due to steel and concrete volumes, often £12,000–£30,000+. Tight access in SW1/SW3 and parking logistics can also affect the total.
Most foundation works take 3–10 working days from excavation to pour, depending on size and complexity. Simple strip foundations can be completed in under a week, while raft or deep foundations may take 1–3 weeks. Timescales are influenced by access for machinery, removal of spoil, inspection bookings for Building Control, and curing time before loading. We programme deliveries carefully to suit Knightsbridge restrictions.
Foundations themselves are usually part of an extension or structural project, so planning depends on the overall scheme rather than the concrete alone. Many rear extensions can fall under permitted development, but conservation areas, listed buildings and mansion blocks often have extra constraints. Building Regulations approval is typically required, and inspections are standard. We’ll check local requirements and coordinate with your designer/engineer to keep everything compliant.
We provide a 10-year warranty on our foundation workmanship, covering defects arising from installation, reinforcement placement and concrete works carried out by our team. It’s designed to give peace of mind on structural stability and durability when used as intended and built to the agreed specification. We also document key stages, including steel fixing and pour details, to support Building Control sign-off and future property records.
We install strip foundations, pad foundations, raft foundations and reinforced wall footings, with options for deeper excavations where required. Concrete mixes can be specified for strength class, sulphate resistance and workability to suit ground conditions and pour method. Reinforcement can include mesh, rebar cages and starter bars for walls or columns. We work with your engineer to select the safest, most cost-effective design for the structure and site constraints.
