A shed is only as good as the base beneath it, especially with Raynes Park’s mix of lawns, patios and tight side access. We build bases that prevent rocking, pooling water and premature rot, whether you’re near Raynes Park station or closer to Cannon Hill Common. From compact tool sheds to larger workshops, we create a level finish ready for immediate installation. Every base is sized precisely to your shed footprint and door clearance.
Homes across SW20 range from Victorian terraces to Edwardian houses and 1930s semis, and each garden brings different challenges. Narrow passages, stepped patios and older drainage runs are common around Raynes Park and neighbouring Wimbledon and New Malden. We plan the base to suit your property layout and how you’ll use the shed, including heavier loads like bikes, gym equipment or ride-on mowers. If you’re in the shed bases Raynes Park area, we’ll recommend the most practical build for your ground and access.
Our process starts with a site visit, accurate measuring and ground preparation, then a base build designed for stability and drainage. We excavate to the right depth, install a well-compacted sub-base, and finish to clean, square lines so your shed sits true. You’ll get clear options, tidy working practices, and a written 10-year warranty for peace of mind. Local homeowners choose us for reliable scheduling, strong finishes and no shortcuts.
Raynes Park gardens often have mixed ground—old patio sub-layers, compacted clay pockets and tree roots near green spaces like Prince George's Playing Fields. We adapt excavation depth and sub-base build-up to prevent future settlement, and we plan for practical access and parking on residential roads. Where drainage is limited, we incorporate falls and permeable options to keep water moving away from the shed. We also work neatly around existing paths, fences and mature planting typical of Merton family homes.

Costs vary by size, access and base type. As a guide in SW20, small paving-slab bases often start around £350–£700, while concrete bases for medium sheds commonly fall between £700–£1,500. Larger workshop bases, difficult access, removal of old slabs, or extra excavation and spoil disposal can take it to £1,500–£3,000+. We’ll provide a clear itemised quote after measuring.
Most shed bases take 1 day from start to finish, especially slab or plastic grid bases with straightforward access. Concrete bases can take 1–2 days depending on excavation and shuttering, plus curing time before the shed is fixed down (typically 48–72 hours for light use, longer for heavy loads). Timelines are affected by base size, ground conditions, steps or narrow side access, and weather.
In many cases, a shed and base in a rear garden is permitted development, provided it meets height, location and use rules. However, restrictions can apply for listed buildings, flats, or if there are specific conditions on your property. Drainage and surface water management may also matter if you’re creating an impermeable area. We’ll flag likely issues during the survey and can advise what to check with Merton Council before work starts.
Yes. We provide a 10-year warranty on workmanship for our shed bases, covering issues such as settlement caused by inadequate preparation, loss of level, or edge failure where the base was built to our specification. It also covers defects in installation of the base structure (sub-base, bedding and finish). The warranty excludes damage from third-party work, flooding events, or changes to ground levels after completion.
We install concrete bases for maximum strength, paving slab bases for a neat, cost-effective finish, plastic grid bases for permeable, well-draining support, and timber bases where a raised solution suits the garden. We’ll help you choose based on shed weight, intended use, drainage needs and access. Options include edging details, falls for run-off, and base oversize allowances for cladding or door thresholds. We also match sizes to manufacturer requirements.
