Soho projects often start with challenging access, tight courtyards and busy streets around Carnaby Street and Soho Square. We provide complete groundwork packages, from site clearance and excavation to foundations and drainage. Whether you’re preparing for an extension, patio, or structural repairs, we set out levels accurately and keep the site organised. Our team coordinates deliveries and waste removal to minimise disruption in W1.
Property in Soho ranges from Georgian townhouses to mansion flats and commercial conversions, each with different structural demands. Older buildings can hide shallow footings, mixed ground layers and legacy drainage routes. We’re used to working carefully around party walls, basements, and shared access points common near Fitzrovia and Leicester Square. Every job begins with practical checks so the build-up, falls and load paths are right first time.
We plan the sequence: clearance, dig, spoil management, drainage runs, then concrete and retaining structures. You’ll get straightforward updates, clear scope, and a site kept safe for residents and neighbours. Our workmanship is backed by a 10-year warranty, and we only use proven materials and correct compaction methods. Homeowners trust us because we don’t cut corners on levels, reinforcement, or drainage testing.
Working in the City of Westminster means managing restricted access, loading times and careful parking plans. In Soho, we often use smaller plant, phased deliveries and quieter methods where neighbours are close. We also account for older services, cellar voids and mixed construction typical of W1 buildings. Where required, we liaise with Building Control and keep documentation tidy for your project file.




Rated 4.9/5 from over 280 verified reviews
Costs vary with access, depth of dig, spoil disposal and whether you need drainage or retaining walls. As a guide in Soho (W1), small site clearance and levelling may start from £800–£2,000. Excavation with waste removal and a concrete base is often £2,500–£7,500. Full groundwork for an extension (foundations, drainage, concrete) commonly ranges £8,000–£25,000+ depending on engineering requirements.
Minor works such as clearance, levelling and small concrete pads typically take 1–3 days. Drainage upgrades and larger excavations are usually 3–7 working days. Extension groundworks (foundations, drainage connections, slab preparation) often run 1–3 weeks. Timescales depend on access restrictions, depth and ground conditions, utility locations, inspections, and curing time for concrete before the next trade can proceed.
Many garden and driveway groundwork projects are permitted development, but there are important exceptions in the City of Westminster, especially for listed buildings, conservation considerations, and works affecting highways or drainage connections. Building Regulations may apply for foundations, structural work and certain drainage changes. We’ll flag likely permissions early, check requirements for your address, and help you align the groundwork scope with any approvals and inspections needed.
Fine Landscaping provides a 10-year warranty on workmanship for our groundwork installations, including correctly built sub-bases, concrete work, retaining walls and drainage we install. The warranty covers defects arising from installation methods, such as settlement due to improper compaction or poor falls causing standing water. It doesn’t cover damage from third-party works, extreme events, or changes to site loading beyond the original design.
We tailor the build-up to the finish and site constraints. Popular options include reinforced concrete slabs for extensions, permeable sub-bases for driveways, French drains and channel drains for surface water, and retaining walls in concrete block, brick-faced or poured concrete. We also design access roads and temporary haul routes where needed. We’ll advise on durability, drainage compliance, and the best specification for your property type and usage.
