Whether you’re upgrading a garden, adding a driveway or preparing for an extension, good groundwork is what keeps the project on track. We handle site clearance, excavation, levelling and drainage with minimal disruption to your home. Our team regularly works around Streatham High Road and near Streatham Common, where access and neighbours are close by. Expect clear communication, safe working and clean handovers.
Streatham’s mix of Victorian and Edwardian houses, mansion flats and newer apartments often brings different groundwork challenges. Period properties can have shallow original footings, tight side access and mature planting to protect. In Streatham Hill and Streatham Vale, we frequently plan spoil removal, deliveries and machinery choice carefully to suit narrow drives and shared boundaries. We tailor foundations, retaining walls and concrete bases to the structure and the soil conditions on site.
We start with a site visit, levels check and a practical plan for excavation, drainage runs and finished falls. You’ll receive a written scope, staged schedule and transparent allowances for muck-away and materials. Our groundwork is installed to recognised standards, with careful compaction and quality control at each layer. Homeowners choose us because we turn up when we say we will and leave the site safe and organised every day.
As groundwork contractors in London Borough of Lambeth, we plan for permit parking, restricted access and considerate working hours. Around SW16 and SW2, gardens can be long and narrow, so we choose machinery and delivery methods that protect paths and shared accessways. We also account for tree roots and green-space proximity near Rookery Gardens and Streatham Common. Where required, we coordinate waste transfer notes and drainage connections to keep everything compliant.

Costs vary with access, depth of dig, spoil removal and whether you need drainage or concrete. As a guide, small site clearance and levelling jobs often start from £800–£2,000. Excavation with muck-away and a concrete base is commonly £2,500–£6,500. Larger packages including foundations, drainage runs and retaining walls can range from £7,000–£20,000+. We provide a detailed, itemised quote after a site visit.
Most domestic groundwork takes 2–10 working days depending on size and complexity. Simple clearance and levelling may be completed in 1–3 days, while drainage plus concrete bases typically take 4–7 days including curing time. Foundations for an extension can take 1–2 weeks, especially if deeper excavations or inspections are needed. Access constraints, weather, hidden obstructions and spoil removal logistics can all affect the programme.
Many garden groundworks are permitted development, such as replacing a patio or installing drainage within your boundary. Planning can be required for new or widened access, significant changes to levels, works near protected trees, or if your property is listed or in a conservation area. For driveways, rules around permeable surfacing and water run-off are important. We flag likely permissions early, check Lambeth guidance, and can work with your architect or surveyor as needed.
