Whether you’re extending a kitchen, adding a garden room or rebuilding steps, the foundation is what keeps everything true and crack-free. We install strip foundations, pad foundations, raft foundations and wall footings to suit your structure and soil conditions. Working around Marylebone High Street and Baker Street, we plan pours and deliveries to minimise disruption. Our team coordinates excavation, reinforcement and concrete placement with precision.
Marylebone’s Georgian townhouses, mansion blocks and period conversions often bring tight side access, shared boundaries and sensitive party wall considerations. We’re used to working in W1 where basements, older drains and mixed ground layers can complicate excavation. If you’re in Regent’s Park edges, Fitzrovia or Mayfair, we tailor depths and reinforcement to the load and layout. This is concrete foundations Marylebone area work done with care for heritage details and neighbouring properties.
We start with a site visit, levels check and an engineering-led method statement where required. You’ll get a clear scope covering excavation, spoil removal, formwork, steel reinforcement, concrete spec and curing time. We build to Building Regulations, arrange inspections, and keep the site safe and tidy throughout. Homeowners choose us for concrete foundations in City of Westminster because we communicate well, document properly and deliver foundations that don’t move.
Access and parking in Marylebone can be restrictive, so we schedule deliveries and concrete pours carefully and use smaller plant where needed. Ground conditions vary, with made ground and older services common around W1, so we locate utilities and adjust depths accordingly. We’re familiar with City of Westminster expectations and work smoothly with Building Control. For mansion blocks and tight mews-style access, we plan noise, waste and neighbour considerations from day one.




Rated 4.9/5 from over 280 verified reviews
Costs in Marylebone vary with depth, access, spoil removal and the foundation type. As a guide, small pad foundations for posts or a garden room may start from £800–£2,000, while strip foundations for an extension often fall around £3,000–£10,000+. Raft foundations and deep/reinforced solutions can be £8,000–£25,000+ depending on size and engineering. We provide a detailed breakdown after a site visit.
Most foundation jobs take 2–7 working days from excavation to pour, plus curing time before building continues. Simple pads can be completed in a day or two, while strip foundations for an extension may take a week depending on spoil volumes and inspections. Raft foundations typically take longer due to formwork and reinforcement. Timescales are affected by access in W1, weather, ground conditions and Building Control scheduling.
Concrete foundations themselves usually fall under the wider project rules, and many rear extensions or garden structures can be permitted development. However, City of Westminster may have restrictions for listed buildings, conservation areas, basement works, or changes near boundaries. Building Regulations approval and inspections are normally required for structural foundations. We’ll advise on likely permissions, liaise with your designer/engineer, and ensure the groundwork meets Building Control requirements before you build up.
We provide a 10-year warranty on our concrete foundation workmanship, covering defects arising from installation such as incorrect levels, inadequate compaction, or reinforcement placement issues. The warranty applies when the build follows the agreed design and loading assumptions, including any engineer’s specification. We also keep records of concrete grade, reinforcement and inspections for peace of mind. If an issue is linked to our work, we’ll put it right promptly.
We offer strip foundations for load-bearing walls, pad foundations for posts and point loads, and raft foundations where ground is variable or loads are spread. Options include reinforced concrete with rebar cages, deeper trench-fill solutions, and wall footings tailored to brick/block or retaining walls. Concrete grade and reinforcement are selected to match engineering and Building Regs needs. We’ll assess access, soil and structure, then recommend the safest, most cost-effective specification.
