From garden overhauls to extension prep, our groundwork team supports projects across SE11 and around The Oval cricket ground. We manage site clearance, excavation and levelling so your build begins on stable, accurately set-out ground. Whether access is via a narrow side return or a shared passage, we plan deliveries and spoil removal to keep disruption down. Drainage and concrete work are completed to specification, ready for the next trade.
Oval’s Georgian townhouses, Victorian terraces and mansion flats often come with compact rear gardens and tight boundaries. That means careful digging near neighbouring structures, thoughtful retaining wall design, and tidy reinstatement of paths and steps. We’re used to working around mature planting, cellar lightwells and older drains that may need upgrades. If you’re in Kennington or Vauxhall, we’ll tailor the method to the property and the access.
We start with a site visit, levels check and a practical scope covering excavation depths, spoil volumes and drainage routes. You’ll receive a written plan, staged programme and clear inclusions before work begins. Our team works safely, keeps the site orderly, and signs off each stage before moving on to foundations, concrete pours or access roads. Homeowners choose us for consistent communication, dependable timelines and a finish that supports the build above.
As groundwork contractors in London Borough of Lambeth, we factor in controlled parking, restricted access and busy roads near Oval tube station. Many plots have limited storage space, so we schedule grab lorries and deliveries precisely. We also watch for older clay drains and mixed ground conditions common around period terraces. Where needed, we coordinate inspections and ensure drainage falls and foundation depths meet the project engineer’s requirements.

Costs in Oval vary with access, excavation depth, spoil removal and whether you need drainage, foundations or concrete. As a guide, small site clearance and levelling may start from £800–£2,000. Drainage repairs or new runs are often £1,500–£5,000. Foundations and concrete bases for extensions typically range £5,000–£20,000+, especially where access is tight or underpinning/engineering is required.
Simple clearance and levelling can take 1–3 days. Drainage upgrades are commonly 2–7 days depending on pipe runs, manholes and connection points. Foundations and concrete work for an extension often take 1–3 weeks including excavation, forming, pours and curing time. Timescales depend on access near Kennington Park, weather, hidden obstructions, and whether inspections or engineering sign-off are needed.
Many garden groundwork jobs are permitted development, but rules can change with listed buildings, conservation areas, new or altered access roads/driveways, and drainage connections. In the London Borough of Lambeth you may also need to follow guidance on surface water, permeable finishes and highway crossings. We’ll flag likely permissions early, help with drawings/specs, and coordinate with your builder or designer so everything stays compliant.
We provide a 10-year warranty on our workmanship for qualifying groundwork installations, including concrete bases, drainage we install, retaining walls and properly specified foundations. The warranty covers defects arising from installation issues, not damage from third-party works, extreme events or misuse. We also document materials and methods used, and we’ll advise on maintenance and loading limits so the finished ground performs as intended.
We can build concrete slabs (reinforced where required), MOT Type 1 sub-bases, permeable aggregates, and drainage solutions such as channel drains, soakaways and new manholes. For retaining walls, options include concrete block with render, brick to match period terraces, or sleeper-style walls where suitable. We’ll recommend the right build-up based on levels, soil, intended use and access, then price options clearly for comparison.
