A well-built base is what keeps your shed, summerhouse or hot tub stable for years. We install concrete bases across SW18, with careful excavation, compacted sub-base and a clean, level finish. If you’re near Southfields tube station or walking distance to Wimbledon Park, we can survey quickly and advise on the right thickness and reinforcement. Every base is set out accurately to suit your structure’s footprint and access.
Southfields homes often have long, narrow gardens behind Victorian terraces and Edwardian houses, plus wider plots around 1930s semis. That mix affects access, spoil removal and how we bring materials through side returns or alleyways. We regularly build concrete bases Southfields area homeowners need for greenhouses, garages and outbuildings where levels can change along the garden length. Our recommendations balance durability with a tidy finish that suits period properties.
We start with a site visit, confirm levels, check drainage falls, then prepare a solid sub-base before pouring. Bases can be reinforced where loads are higher, such as hot tubs or garage bases, and we finish to tight tolerances for easy installation. You’ll get clear timescales, straightforward communication and a site left neat at the end of each day. Local clients choose us for reliable workmanship and concrete bases in London Borough of Wandsworth that last.
In Southfields, access can be tight around side passages and shared drives, especially near Earlsfield and Putney borders. We plan deliveries, barrowing routes and waste removal to minimise disruption and protect paving. Ground conditions vary from firm subsoil to softer, made-up garden areas, so we adjust excavation depth and sub-base build-up accordingly. We also factor in London Borough of Wandsworth requirements where drainage or hardstanding rules apply.

Costs depend on size, thickness, access and whether reinforcement is needed. As a guide, small shed bases often start around £450–£900, while larger summerhouse or greenhouse bases are commonly £900–£1,800. Hot tub bases and garage bases, which may need thicker concrete, steel mesh and extra sub-base, typically range from £1,500–£3,500+. We’ll provide a tailored quote after a site survey in SW18.
Most shed or greenhouse bases can be completed in 1 day, including excavation, sub-base and pour, with light foot traffic usually possible the next day. Larger summerhouse bases typically take 1–2 days, and garage or hot tub bases may take 2–3 days if extra digging, reinforcement or drainage is required. Weather, access through the property, and spoil removal are the main factors that affect timing.
In many cases, a concrete base for a shed, greenhouse or summerhouse is permitted development, provided the overall structure meets height and location rules. However, restrictions can apply for front gardens, listed buildings, conservation areas, or where drainage and permeable surfacing are required. We’ll ask the right questions and can help you check London Borough of Wandsworth guidance before work starts, so you avoid compliance issues.
We provide a 10-year warranty on our concrete base workmanship, covering issues such as settlement caused by inadequate sub-base preparation, poor compaction, or incorrect finishing levels. It also includes defects linked to our installation of reinforcement and edge formwork. Normal wear, impact damage, or problems caused by third-party alterations aren’t covered. We’ll explain care and curing times so your base reaches full strength as intended.
We can build standard floated slabs for sheds and summerhouses, reinforced bases for hot tubs and garages, and tailored greenhouse bases with perimeter upstands or anchor points. Options include brushed or smooth finishes, thickened edges, and integrated drainage falls or channels where needed. We’ll advise on slab thickness, mesh type and base size to match your structure’s load and manufacturer requirements, while keeping access and budget in mind.
