Whether you’re upgrading a courtyard near Victoria or reworking a rear garden close to Westminster Abbey, ground preparation makes the difference. Our team handles site clearance, excavation, levelling and grading so your new landscaping sits true and drains correctly. We also manage waste removal responsibly, keeping disruption low for neighbours and building managers. From small access routes to complex layouts, we set the groundwork for premium finishes.
The City of Westminster is known for Georgian townhouses, mansion flats and luxury apartments, often with compact gardens and shared access. These properties frequently need precise excavation depths, clean edges and careful spoil handling to protect existing structures. We’re experienced with tight SW1 working conditions, including basement-adjacent walls, lightwells and older drainage runs. If you’re planning a patio, lawn, planting scheme or new steps, we’ll build the base to suit the property and the load.
We start with a site visit to check levels, falls, drainage routes and access, then provide a clear scope of works. Our crew completes clearance, excavation and foundations with measured tolerances, followed by levelling and grading to the agreed finish levels. We keep the site tidy, organise waste removal, and coordinate deliveries to minimise downtime. Homeowners choose us for straightforward communication, reliable scheduling and workmanship backed by warranty.
Working around Whitehall and Pimlico often means restricted parking, narrow access and strict site housekeeping. We plan deliveries, barrowing routes and waste collections to suit SW1 constraints and building rules. Older properties can hide legacy drains and mixed ground layers, so we confirm depths, falls and bearing conditions before foundations go in. Our approach keeps neighbouring structures protected and ensures compliant, durable results.

Costs vary with access, spoil volume and whether drainage or foundations are needed. As a guide in Westminster, small clearance and levelling jobs often start around £900–£2,000. Typical groundwork packages for a patio or lawn base are commonly £2,500–£6,500. Larger projects with excavation, new drainage runs and concrete foundations can range from £7,000–£15,000+. We itemise costs after a site survey.
Most garden groundworks in the Westminster area take 2–7 working days, depending on excavation depth, access and waste removal logistics. A straightforward clearance and level for a small courtyard can be 1–2 days, while full preparation for patios, paths and drainage commonly takes a week. Timescales can extend if we uncover old drains, need additional foundations, or must coordinate skips and deliveries around parking restrictions.
Many garden groundwork elements are permitted development, especially like-for-like repairs, levelling and sub-bases for patios. However, rules can change if you’re altering drainage connections, working near a listed building, changing boundary walls, or installing impermeable surfacing at the front. In the City of Westminster, we’ll flag likely approvals early and can work with your designer or architect to ensure materials, falls and drainage comply with local requirements.
We provide a 10-year warranty on our workmanship for garden groundworks, covering issues such as sub-base failure, settlement caused by incorrect compaction, and defects in installed foundations or drainage components (where supplied and fitted by us). The warranty doesn’t cover damage from third-party works, extreme events, or changes to loads beyond the original design. We also keep clear records of depths, materials and compaction methods used.
We prepare bases for porcelain and natural stone patios, block paving, resin-bound surfaces (with suitable sub-base), turf and seeded lawns, raised beds, and garden steps. Drainage options include soakaways, channel drains and correctly graded falls to planting zones. We’ll advise on build-ups, edging details and foundation depths based on your finish choice, expected foot traffic, and the constraints of Westminster access and property structure.
