From Pimlico courtyards to Victoria mews access, groundwork in Westminster demands careful planning and precision. We prepare sites for landscaping, extensions and outdoor living spaces with professional excavation, levelling and concrete work. Working close to landmarks such as Westminster Abbey often means tighter access and stricter controls, so we programme deliveries and spoil removal to minimise disruption. The result is a stable base that keeps your project on track.
The City of Westminster includes Georgian townhouses, mansion flats and high-spec apartments, each with different structural and access challenges. Older properties can hide shallow services, historic drains or fragile boundary walls that need protection during excavation. Basement lightwells, shared freeholder areas and narrow side returns are common, especially around SW1. Our team adapts methods and machinery to suit confined spaces without compromising on build quality.
We start with a site visit, utility checks and a clear scope for excavation, foundations, drainage runs and levels. You’ll receive a straightforward programme, waste management plan and method statements where required. We keep the site orderly, protect neighbouring areas, and sign off key stages before moving forward. Homeowners choose us because we’re responsive, transparent, and we stand behind our workmanship with long-term cover.
Westminster sites often have restricted access, controlled parking and tight delivery windows, particularly around Whitehall and St James’s. We plan logistics, use compact plant where needed, and keep footways and shared entrances clear. Ground conditions and existing services can vary between older terraces and modern developments, so we verify depths, falls and connections before breaking ground. We also work with City of Westminster requirements and liaise with building control when the scope demands it.

Costs vary with access, depth of dig, spoil removal and whether you need drainage, foundations or concrete bases. As a guide in Westminster, small site clearance and levelling might start around £800–£2,000. Drainage works are often £1,500–£4,500, while foundation and concrete base packages commonly fall between £3,000–£12,000+. We’ll survey and provide an itemised estimate.
Minor works such as localised excavation, levelling or a short drainage run can take 1–3 days. A typical groundwork package for a garden redesign (clearance, excavation, sub-base and concrete) is often 1–3 weeks. Timings depend on access for machinery, skip permits, depth of foundations, weather, and what we uncover underground. We provide a realistic programme and keep you updated daily.
Many garden and driveway groundwork elements are permitted development, but Westminster properties can have extra constraints, especially in conservation areas or listed buildings. Permissions may be needed for changes affecting highways, significant retaining walls, or drainage connections. We’ll flag likely requirements early, help you understand what applies, and coordinate with building control where structural foundations are involved. If permits are needed, we can guide the process.
We provide a 10-year warranty on workmanship for qualifying groundwork installations, including prepared sub-bases, concrete work, drainage installation and retaining wall construction. The warranty covers defects arising from our installation rather than accidental damage or third-party alterations. We also document key stages (levels, falls, compaction and materials) so you have a clear record of what’s been built. Terms are explained in writing before we start.
Options depend on your build and ground conditions. For drainage, we can install channel drains, soakaways, French drains and new pipe runs with inspection chambers. Concrete work ranges from reinforced slabs to footings for walls and outbuildings. Retaining walls can be engineered block, brick to match existing, or sleeper-style where suitable. We’ll recommend the best specification based on levels, loads, aesthetics and budget.
