Holland Park projects often demand precise groundwork, especially close to Holland Park and the Design Museum where access can be tight and neighbours are close. We install concrete foundations for extensions, garden studios, retaining walls and structural landscaping. Options include strip foundations, pad foundations, raft foundations and wall footings, designed to suit the load and soil conditions. Every base is set out accurately to protect your build from settlement and cracking.
Many homes around W11 and W14 are large Victorian houses, mansion conversions and other period properties, where existing structures and party walls need careful consideration. We’re used to working with basements, rear additions and side returns that call for deeper foundations or reinforcement. Where ground conditions vary, we specify the right depth, steel reinforcement and concrete strength to match. Our team coordinates with your architect or engineer so the foundation design fits the wider build.
We start with a site visit, levels check and a clear method statement, then manage excavation, spoil removal and concrete pours with minimal disruption. Foundations are installed to engineering requirements and aligned with Building Regulations, with inspections booked as needed. You get tidy workmanship, clear communication and documented handover notes for your records. Homeowners choose us for dependable scheduling, careful detailing and a finish that supports the next trade without delays.

Costs vary with foundation type, depth, access and spoil removal. As a guide, small pads for posts or a garden room may start around £900–£2,500. Strip foundations for a typical rear extension are often £4,000–£12,000 depending on depth and ground conditions. Raft foundations commonly range from £8,000–£20,000+. Engineering design, reinforcement, pumping and Building Control inspections can add to the total.
Most foundation packages take 3–10 working days from set-out to pour, depending on size and complexity. Small pad foundations can be completed in 1–2 days, while strip foundations for an extension often take 4–7 days including excavation, forming and concrete curing time. Raft foundations may take 1–2 weeks. Timescales are affected by access, weather, inspections, service diversions and whether deeper foundations are required.
Foundations themselves usually fall under Building Regulations rather than planning permission, but the overall project (extension, outbuilding or structural works) may need planning consent. Building Control approval and inspections are typically required for excavation depth, reinforcement and the concrete pour. In the Royal Borough of Kensington and Chelsea, there may also be rules on skips, parking suspensions and working hours. We help you check requirements and coordinate inspections so the job stays compliant.
Yes. We provide a 10-year warranty on our concrete foundation workmanship, covering defects caused by installation issues such as incorrect set-out, inadequate compaction or poor concrete placement. It also covers failures linked to our reinforcement and footing construction where specified. The warranty doesn’t cover problems caused by later structural changes, extreme events, or designs altered by others after installation. We keep clear records of levels, reinforcement and pour details for peace of mind.
