From side returns to garden studios, a reliable base is what keeps walls straight and floors crack-free. Our team delivers foundations across TW1 and TW2, working on projects near Twickenham Stadium and along the riverside routes by Marble Hill Park. We handle excavation, formwork, concrete pours and wall footings as one coordinated package. Every foundation is set out accurately so the build above goes smoothly.
Twickenham’s housing mix often calls for tailored groundwork solutions. Victorian villas and Edwardian houses may have shallow existing footings or tight side access, while 1930s family homes often suit straightforward strip foundations for extensions. We assess load paths, drainage runs and nearby trees before choosing the right approach. If ground conditions or design loads demand it, we specify reinforced or deep foundations to keep movement to a minimum.
We start with a site visit, levels check and an engineering-led recommendation: strip foundations, pad foundations, raft foundations or wall footings. Depths, widths and reinforcement are set to meet Building Regulations, and we coordinate inspections at the right stages. You’ll get a written scope, clear programme and tidy working practices with safe spoil removal. Homeowners choose us for dependable workmanship and a 10-year warranty on our foundation works.
Working in the London Borough of Richmond upon Thames means planning for narrow driveways, parking controls and considerate working hours. In Twickenham and St Margarets, access can be restricted, so we plan deliveries, mini-diggers and concrete pours to avoid disruption. Proximity to mature trees and older drainage can affect foundation depths, so we assess risks early and adapt with deeper footings or reinforcement. We also liaise with Building Control to keep inspections on track.

Costs vary with foundation type, depth, access and spoil removal. As a guide, small pad foundations for posts or a garden room often start around £900–£2,000. Strip foundations for a typical extension are commonly £3,500–£9,000, while raft foundations can range from £7,000–£18,000+. Engineering design, reinforcement, poor ground, and restricted access in TW1/TW2 can increase the budget.
Most domestic foundation jobs take 2–5 working days from excavation to pour, with curing time afterwards before heavy loading. A simple set of pads may be completed in 1–2 days, while strip foundations for an extension can take 3–7 days depending on trench depth and weather. Raft foundations usually take longer due to sub-base preparation, insulation, steel fixing and formwork. Access and Building Control inspection timing also affect duration.
Foundations themselves are usually covered as part of the overall build, and many small garden structures can fall under permitted development. However, extensions, outbuildings near boundaries, and work affecting drainage or party walls may need approvals. Building Regulations approval is typically required for structural foundations, with inspections at key stages. We’ll advise what applies to your project and coordinate with Building Control, and we can flag when planning or a party wall agreement is likely.
We provide a 10-year warranty on our concrete foundation installations, covering workmanship and defects in the foundation build-up (such as incorrect set-out, inadequate reinforcement where specified, or poor compaction leading to settlement). The warranty applies when the foundation is used as designed and not altered without approval. We also keep records of depths, reinforcement and inspection stages for peace of mind. Any manufacturer warranties on materials are passed on where applicable.
We offer strip foundations for loadbearing walls, pad foundations for posts and steelwork, and raft foundations where ground conditions or load spread make them sensible. Options include reinforced steel cages, deeper trench fills, insulated rafts, and engineered wall footings for retaining or stepped ground. Concrete mixes can be specified for strength and exposure conditions, and we can incorporate service ducts and drainage penetrations. We’ll recommend the most cost-effective, Building Regs-compliant design for your layout.
