Whether you’re planning an extension, garden room or structural landscaping, the foundation is what makes it last. We deliver engineered concrete bases across SE21, with careful excavation, shuttering and accurate pours. Work is planned around local access and neighbours, including jobs near West Dulwich station and Belair Park. You get a solid, level platform ready for the next trade.
West Dulwich’s leafy streets include Victorian villas, Edwardian houses and period conversions, often with tight side access and mature gardens. These properties can involve variable ground conditions and existing drainage runs that must be protected. We design foundations to suit the load and layout, including wall footings for new masonry and reinforced sections where required. If you’re close to Dulwich Village or Herne Hill, we’ll factor in restricted parking and delivery timing from day one.
Our process starts with a site visit, levels check and a discussion of what you’re building and where the loads will sit. We then specify the right solution—strip foundations, pad foundations, raft foundations or deep foundations—supported by engineering where needed. Every pour is set out accurately, reinforced correctly and finished to the tolerances your builder expects. Homeowners choose us for tidy working, clear communication and a 10-year warranty on our foundation workmanship.
Ground conditions in the concrete foundations west dulwich area can vary between made ground, clay and tree-influenced soils, especially near Dulwich Wood and older gardens. We assess depth, drainage and nearby structures, then adapt with deeper digs, reinforcement or a raft where settlement risk is higher. Access can be narrow on period plots, so we plan barrowing routes, concrete deliveries and safe storage. We also coordinate inspections and paperwork for concrete foundations in London Borough of Lambeth projects.

Costs depend on depth, soil, access and the foundation type. As a guide, small pad foundations for posts can start from £250–£600 each, while strip foundations for an extension commonly fall around £120–£220 per linear metre. Raft foundations are usually priced by area, often £140–£260 per m². Deep foundations and heavy reinforcement increase costs. We provide itemised estimates after a site visit in SE21.
Most domestic foundation jobs take 1–3 days for excavation, set-out and reinforcement, with concrete poured on the same or following day. Larger footprints or raft foundations may take 3–7 days, especially if access is limited or spoil removal is slower. Timescales also depend on inspection scheduling, weather, and whether deeper digs are required due to soil conditions or nearby trees. Curing time is allowed before building loads go on top.
Foundations themselves usually form part of a wider project (extension, outbuilding or structural landscaping). Planning permission isn’t always required, but Building Regulations approval is commonly needed because foundations are structural. In the London Borough of Lambeth, we help you confirm whether your project is permitted development and whether there are constraints such as party wall matters, drainage consents or tree protection. We also prepare for Building Control inspections at key stages.
We provide a 10-year warranty on our foundation workmanship, covering defects caused by installation issues such as incorrect set-out, inadequate compaction, or reinforcement not installed to the agreed specification. It also covers problems arising from poor concrete placement or finishing that affects structural performance. The warranty doesn’t cover movement from unrelated structural changes, extreme weather events, or issues caused by other trades. You’ll receive clear documentation of what’s included.
We offer strip foundations for loadbearing walls, pad foundations for posts and steel columns, and raft foundations where ground conditions or load spread make them sensible. Options include reinforced concrete, thicker edge beams, and wall footings tailored to blockwork or brickwork. Where depths are significant, we can design deep foundations with engineering input. We’ll advise based on your build, soil, nearby trees, drainage runs and access, then confirm the spec for Building Regs.
