A well-built base is what stops a shed door sticking, a hot tub settling, or a greenhouse frame twisting over time. We install concrete bases across Chelsea, including SW3 and SW10, with careful levels and clean edges. Whether you’re near King’s Road or walking distance from the Saatchi Gallery, we plan the pour around access and neighbours. The result is a slab that looks neat and performs for years.
Chelsea homes range from Georgian townhouses with compact courtyards to Victorian mansions with mature gardens, plus luxury apartments with landscaped communal areas. These properties often need precise, low-disruption groundwork and a finish that suits premium outdoor spaces. We’re used to tight side returns, basement lightwells, and delicate paving that must be protected. If you need concrete bases Chelsea area homeowners rely on, we tailor the build to your plot and structure.
We start with a site visit to confirm sizes, load requirements, and drainage routes. Ground is excavated and compacted properly, then we install formwork, sub-base, and reinforcement where needed before pouring and finishing to level. We keep you informed on curing times so you know exactly when you can install your shed, summerhouse, or hot tub. Clients choose us for consistent workmanship, tidy working practices, and a clear 10-year warranty.
Chelsea sites often involve restricted access, controlled parking, and considerate working hours, especially near busy roads and mews. We plan deliveries, spoil removal, and concrete pours to minimise disruption and keep entrances clear. Ground conditions can vary between made-up ground and older garden soils, so we assess compaction and specify the right sub-base and reinforcement. We also keep finishes sympathetic to period properties and high-end landscaping schemes.

Costs depend on size, thickness, access, and whether reinforcement and drainage are required. As a guide, small shed or greenhouse bases often start around £450–£900, while larger summerhouse bases are commonly £900–£2,000. Hot tub and garage bases typically range from £1,500–£4,500 due to thicker slabs and steel mesh. Tight access in SW3/SW10 can affect labour and waste removal.
Most shed, greenhouse, or small summerhouse bases take 1–2 days to excavate, build up, and pour. Larger or reinforced slabs (such as hot tub or garage bases) are usually 2–4 days depending on dig-out depth and spoil removal. Concrete then needs curing time before heavy loads: typically 48–72 hours for light use, and around 7 days before installing heavier structures.
A concrete base in a rear garden is usually permitted development, particularly for sheds, summerhouses, and greenhouses within standard height and boundary rules. However, restrictions can apply to listed buildings, conservation areas, front gardens, and sites with special conditions. We’ll flag likely issues during the survey and can help you check the Royal Borough of Kensington and Chelsea guidance. If drainage changes are needed, we’ll advise on compliant solutions.
Yes. Our concrete base installations come with a 10-year warranty covering workmanship, including issues such as settlement caused by inadequate preparation, poor compaction, or incorrect levels. It also covers defects linked to reinforcement placement and slab integrity when built to the agreed specification. The warranty does not cover damage from third-party alterations, extreme ground movement outside normal conditions, or loads beyond what the base was designed to support.
We can build standard slabs for sheds and greenhouses, thicker reinforced slabs for hot tubs, and larger garage bases with engineered load capacity. Options include brushed or smooth power-floated finishes, formed edges, and falls for surface water drainage. We can also add ducting for electrics, set anchor bolts, or create a perimeter upstand for timber frames. We’ll recommend the best specification based on your structure and garden layout.
