From garden renovations to new patios and outbuildings, good groundwork makes everything that follows safer and longer-lasting. Our team works across SW9, including around Stockwell tube station and the routes between Oval and Brixton. We take care of site clearance, excavation and levelling so your project begins on stable, well-prepared ground. If you need drainage or a concrete base, we can deliver it as part of the same programme.
Stockwell’s mix of Victorian terraces, Georgian houses and post-war estates often means tight side access, shared boundaries and varying ground levels. We regularly support homeowners in the Stockwell area with foundations for garden rooms, retaining walls for sloped plots, and practical access roads for rear works. Where older properties have existing drains or historic hardstanding, we plan carefully to avoid surprises. Our approach suits busy households who want clear communication and minimal disruption.
We start with a site visit to assess levels, access, drainage routes and any structural requirements. You’ll receive a clear scope of works covering excavation, foundations, concrete work and reinstatement, with sensible options where budgets differ. We protect neighbouring areas, keep the site organised, and schedule deliveries to suit local restrictions. Homeowners choose us for dependable workmanship, transparent updates and a 10-year warranty on qualifying groundwork installations.
Working in the London Borough of Lambeth often involves controlled parking, narrow streets and limited skip placement, especially near Stockwell Park and surrounding residential roads. We plan logistics early, including waste removal and delivery timings, to keep disruption down. Many properties have older drainage runs and mixed ground build-ups, so we allow for careful tracing and sensible fall design. Our team adapts methods and machinery size to suit tight access and shared boundaries.

Costs vary with access, spoil removal, depth, and whether you need drainage or concrete. As a guide in Stockwell, small groundwork packages (clearance, minor excavation and levelling) often start around £1,200–£3,000. Concrete bases and foundations commonly fall in the £3,000–£10,000 range depending on size and specification. Larger jobs with drainage runs, retaining walls or access roads can be £10,000–£25,000+.
Many domestic groundwork jobs in SW9 take 2–7 working days, such as site clearance, excavation and preparing a base for a patio or garden room. Foundations and drainage can extend this to 1–3 weeks, particularly where trenches are deeper or access is restricted. Timescales depend on spoil removal logistics, weather, concrete curing, and any unexpected finds like old footings or redundant drains. We provide a realistic programme before starting.
Many garden groundwork tasks are permitted development, such as preparing bases for patios, paths and some outbuildings, provided you follow drainage and surface water rules. However, planning or consent may be needed for major level changes, works near boundaries, new access roads, or if your property is listed or in a conservation area. Lambeth requirements can also affect dropped kerbs and highway-adjacent works. We’ll flag likely permissions and help you check before work begins.
We back qualifying groundwork installations with a 10-year warranty, covering workmanship on items such as concrete bases, foundations, drainage runs and retaining wall construction (where built to the agreed specification). The warranty does not cover damage caused by third-party works, extreme events, or changes to loading beyond design assumptions. We also keep clear records of materials and build-up layers, so future landscaping or building stages can proceed with confidence.
We tailor the build-up to your project: Type 1 sub-base and geotextiles for stable paving, reinforced concrete for heavier loads, and soakaways or channel drains for better surface water control. For retaining walls, popular options include concrete block with render, brick to match period homes, or sleeper-style solutions where suitable. We’ll advise on falls, finished levels and access routes so the groundwork supports your chosen patio, lawn or garden room design.
