Whether you’re planning a new driveway, extension or garden rebuild, quality groundworks set the standard for everything that follows. We support homeowners across TN16 with site clearance, excavation, foundations, drainage and concrete work. Many jobs in the area are influenced by access around Biggin Hill Airport and the lanes leading out towards Cudham. Our team keeps disruption down while keeping your site safe and well organised.
Biggin Hill’s semi-rural character means plots can be larger, sloping or bordered by mature hedging, especially around Aperfield and Berry’s Green. We regularly work on large detached houses, bungalows and period properties where levels, drainage runs and existing services need careful handling. If you’re upgrading an older garden or preparing for a modern extension, we’ll design the groundwork to suit the structure and the land. The result is a base that performs properly in wet weather and heavy use.
We start with a clear site visit, then provide a written scope covering levels, spoil removal, drainage routes and construction build-ups. Our groundwork contractors biggin hill area team uses the right machinery for the access available and protects driveways, paths and boundaries. You’ll get straightforward communication, clean handovers and quality checks at key stages such as compaction and falls. Homeowners trust us because we do the unseen work to a high standard and stand behind it.
Ground conditions around Biggin Hill can vary from firm clay to softer, wetter patches, so we plan excavation depths, sub-bases and drainage accordingly. Access can be tight on rural lanes and shared drives, so we schedule deliveries and plant to minimise disruption. We’re familiar with expectations for works in the London Borough of Bromley, including drainage connections and surface water control. Where plots slope towards gardens or boundaries, we prioritise retaining solutions and stable levelling.

Costs vary with access, spoil removal, depth of dig and whether you need drainage or retaining works. As a guide in Biggin Hill, small site clearance and levelling can start from £800–£2,500. Driveway or patio sub-base and concrete work often falls around £2,500–£8,000. Foundations and drainage for an extension are commonly £6,000–£20,000+. We provide a detailed, itemised estimate after a site visit.
Most domestic groundworks take between 2 days and 3 weeks, depending on scope. A straightforward excavation and concrete base may be completed in 2–5 days, while drainage, retaining walls and access roads can extend the programme. Timescales are affected by weather, ground conditions, service diversions, skip/lorry access and curing time for concrete. We’ll set out a realistic schedule and keep you updated as the job progresses.
Many garden and driveway groundwork elements are permitted development, but there are important exceptions. New or altered access points, major level changes, retaining walls near boundaries, and some drainage arrangements can require approval. Driveways must also manage surface water correctly, often using permeable finishes or on-site drainage. We’ll advise what’s likely to apply in the London Borough of Bromley and can work with your designer or architect to keep everything compliant.
We provide a 10-year warranty on our workmanship for qualifying groundwork installations, including sub-bases, drainage runs, concrete bases and retaining structures we build. It covers defects caused by workmanship, such as settlement from inadequate compaction or incorrect falls affecting drainage performance. The warranty doesn’t cover damage from third-party works, extreme events, or changes to loading beyond the agreed design. You’ll also receive clear maintenance guidance where relevant.
We tailor the build-up to the finished surface and how you’ll use the space. Popular options include Type 1 sub-base for driveways and patios, reinforced concrete bases for garages and garden rooms, and French drains or soakaways for surface water control. For retaining walls we can build concrete blockwork, sleeper walls, or reinforced solutions where required. We’ll recommend options based on levels, soil conditions, access, and your preferred finish.
