If you’re extending, rebuilding or adding a garden structure in SE12, the foundation design matters as much as the build above it. We install strip foundations, pad foundations, raft foundations and wall footings tailored to your site and loads. Working near Lee Green crossroads and around Lee station, we plan deliveries and access to keep disruption down. Every pour is set out accurately, reinforced where required, and finished ready for the next trade.
Lee Green’s housing mix—Victorian terraces, Edwardian semis and many 1930s houses—often comes with varied ground conditions and tight side access. We’re used to underpinning-style depths where needed, and to designing deep foundations when soils or nearby trees demand it. Whether you’re in Hither Green, Blackheath or closer to Grove Park, we match the foundation type to the structure and the ground. That means fewer surprises when Building Control visits and a better base for the life of the property.
Our process starts with a site visit, levels, and a practical engineering-led recommendation. We handle excavation, spoil removal, formwork, reinforcement, concrete placement and curing, with clear checks at each stage. You’ll get straightforward communication, photo updates if you’re off-site, and work completed to Building Regs requirements. Homeowners choose us for reliable scheduling, clean working practices and foundations that don’t cut corners.
Across the London Borough of Lewisham, we regularly see mixed made-ground, clay-heavy patches and tree influence that can affect depth and reinforcement. In the concrete foundations Lee green area, access can be tight and parking controlled, so we schedule pours and muck-away to minimise street impact. We also factor in neighbouring structures common to terraces and semis, protecting boundaries and party walls. Where Building Control inspections are needed, we coordinate timings so your programme keeps moving.

Costs vary by depth, soil conditions, access and the foundation type. As a guide, small pad foundations for posts or garden rooms may start from £400–£900 per pad including excavation and concrete. Strip foundations for an extension often fall around £2,500–£7,500 depending on length and depth. Raft foundations are typically higher, often £6,000–£18,000+, especially if heavily reinforced or requiring additional ground preparation.
Most domestic foundation jobs take 2–7 working days from excavation to pour, with curing time before heavy loading. A few pads can be completed in a day or two, while strip foundations for an extension commonly take 3–5 days depending on spoil removal and inspection timings. Raft foundations can take 5–10 days due to sub-base preparation, formwork and reinforcement. Weather, access near Leegate Shopping Centre routes, and Building Control availability can affect timelines.
Foundations themselves usually don’t require planning permission, but the structure you’re building might. In many cases, rear extensions, outbuildings and garden structures can be permitted development, subject to size and location rules. Regardless, Building Regulations approval is commonly required for structural work, and Building Control may need to inspect excavations before pouring. We’ll advise what’s likely to apply and can liaise with your designer or engineer to keep everything compliant.
We provide a 10-year warranty on our foundation workmanship, covering issues arising from installation defects such as incorrect setting out, inadequate reinforcement placement, or poor concrete placement and finishing. It’s designed to give peace of mind for domestic projects like extensions and garden rooms. The warranty doesn’t cover design changes by others, extreme ground movement outside reasonable expectations, or damage caused by later trades. We also keep clear records of levels, reinforcement and pours for accountability.
We can build strip foundations, pad foundations, reinforced rafts, and wall footings, choosing the right option for load, soil and access. Reinforcement can range from simple rebar cages to heavier meshes for rafts, and we can incorporate starter bars for walls or steelwork. Concrete mixes can be specified for strength and durability, including sulphate-resisting options where required. If you have an engineer’s drawings we follow them; if not, we can guide you on a sensible specification and next steps.
