If you’re adding a shed, summerhouse or hot tub near Tolworth Broadway, the base is what determines how well it performs long-term. We install concrete slabs with a crisp, level finish and the right falls for drainage. From compact patios to larger garden builds, we tailor the thickness and reinforcement to the load. We regularly work across KT5 and KT6 and can advise on the best base size for your kit or frame.
Tolworth’s mix of 1930s semis, post-war houses and modern developments means access and ground build-ups vary street by street. Some gardens have narrow side passages, others have made-up ground from old landscaping. We plan for these realities, including wheelbarrow access, spoil removal and tidy working. If you’re on the Surbiton side or closer to New Malden, we’ll factor in parking and delivery timing too.
Our process starts with a site visit, accurate setting-out, and proper excavation to a stable sub-base. We install edging/shuttering, add reinforcement where required, then pour and finish to a true level (or specified falls). Drainage details are built in so water doesn’t sit under your structure. Homeowners choose us for clear communication, clean workmanship and a 10-year warranty on our base installation.
Across the Royal Borough of Kingston upon Thames, we often find variable ground conditions—clay pockets, compacted fill and uneven garden levels. Near Tolworth Tower and surrounding residential roads, access can be tight, so we plan barrow routes and concrete delivery carefully. We also account for boundary lines, neighbouring fences and existing drainage runs before digging. The result is a base that suits local property layouts and performs through wet winters.

Costs depend on base size, excavation depth, access and whether reinforcement is needed. As a guide, small shed bases often start around £450–£900, while larger summerhouse or greenhouse bases are typically £900–£1,800. Hot tub bases with thicker pours and steel mesh commonly fall in the £1,200–£2,500 range. Garage bases can be £2,500–£6,000+. We’ll confirm after a site visit in the concrete bases Tolworth area.
Most shed or greenhouse bases take 1 day on site, with larger summerhouse or hot tub bases usually 1–2 days depending on excavation and spoil removal. Garage bases can take 2–4 days including sub-base preparation and forming. Weather, access in KT5/KT6, and whether we’re breaking out old concrete can extend timings. We’ll also advise on curing time before loading—typically 48–72 hours for light use, longer for heavy loads.
In many cases, a concrete base for a shed, greenhouse or summerhouse is permitted development, especially when it’s within your garden and the structure meets height and boundary rules. However, restrictions can apply in certain situations (for example, listed buildings, conservation considerations, or if you’re adding a large outbuilding). We’ll talk you through the likely requirements and can help you check guidance for concrete bases in Royal Borough of Kingston upon Thames before work starts.
Yes. Our concrete base installation comes with a 10-year warranty covering workmanship-related issues such as significant settlement, cracking caused by poor preparation, or drainage falls not formed as specified. It assumes normal use and that any structure installed is within the designed load. We also document the build-up (sub-base, reinforcement and pour depth) so you have a clear record. If there’s a problem, we respond quickly and put it right.
We tailor the base to the structure: standard shed bases, thicker reinforced slabs for hot tubs, and larger pads for garages. Options include steel mesh reinforcement, thickened edges, and a brushed or smooth power-float finish depending on use. We can also include drainage falls, perimeter channels, or a slightly raised slab to keep timber frames drier. If you’re unsure, we’ll recommend the best specification after measuring and checking ground conditions.
