If you’re planning an extension, garden room or structural rebuild in SE23, the foundation design is where the success starts. We install strip foundations, pad foundations and raft foundations tailored to your plot and loading requirements. Working close to Honor Oak Park station and up towards One Tree Hill, we’re used to tight access, level changes and careful spoil removal. Every pour is set out accurately, reinforced where required, and prepared for inspection.
Honor Oak’s housing stock ranges from Victorian terraces to Edwardian houses and 1930s semis, each with different footing demands. Older properties often need wall footings that respect existing structures, party walls and neighbouring foundations. Sloping gardens are common, so we plan steps, deeper trenches or engineered solutions to keep levels correct. We also support projects across Forest Hill, Brockley and Nunhead where build constraints can be similar.
Our process starts with a site visit, levels check and a clear scope for excavation, concrete specification and reinforcement. We coordinate with your engineer and Building Control, keeping photo records and pour notes for compliance. You’ll get tidy working practices, safe barriers, and a schedule that accounts for deliveries and curing time. Local homeowners choose us because we communicate clearly and stand behind the work with a written warranty.
The Honor Oak area includes hilly plots, variable made ground and gardens with limited access, so we plan excavation methods carefully. We factor in delivery routes, parking restrictions and concrete wagon access, and can use pumps when needed. For properties near Camberwell Old Cemetery or along busier roads, we also pay close attention to noise, working hours and site safety. This local approach helps keep your concrete foundations in London Borough of Lewisham compliant and efficient.
Rated 4.9/5 from over 280 verified reviews
Costs vary with foundation type, depth, access and how much excavation is required. As a guide in Honor Oak, small pad foundations might start around £900–£2,000, while strip foundations for a typical rear extension are often £3,500–£8,500. Raft foundations and deep foundations can range from £8,000–£20,000+ depending on engineering and reinforcement. We provide a detailed itemised estimate after a site visit.
Most foundation installs take 2–7 working days from excavation to pour, with additional time for inspections and curing. A straightforward strip foundation for an extension is commonly 3–5 days, while raft foundations or deep foundations may take 1–2 weeks due to extra steel fixing, formwork and sequencing. Timescales are affected by access, spoil removal, weather, and Building Control inspection availability.
Foundations themselves usually fall under Building Regulations rather than planning permission, but the overall project (extension, outbuilding or structural work) may need planning approval depending on size and location. In the London Borough of Lewisham, you’ll also need Building Control sign-off for excavation depth, reinforcement and concrete. We liaise with your designer/engineer and support inspections so the work is compliant, recorded and ready for the next build stage.
We provide a 10-year warranty on our concrete foundation workmanship, covering issues arising from installation defects such as incorrect setting-out, inadequate reinforcement placement (where specified), or poor concrete placement/compaction. The warranty is supported by our records of levels, reinforcement and pour details. It doesn’t cover design errors from third parties, changes to loading after completion, or ground movement outside reasonable control, but we’ll always advise on risk reduction.
We install strip foundations, pad foundations, raft foundations and wall footings, with reinforced options where required by engineering calculations. Concrete mixes can be specified for strength, sulphate resistance and durability depending on ground conditions. We can form steps for sloping sites, add starter bars for walls, and coordinate service penetrations for drainage and utilities. We’ll help you choose the most suitable option based on structural loads, access and Building Regs requirements.
