If you’re upgrading your garden near Eastfields station or planning a new build by Figges Marsh, a properly constructed base makes all the difference. We install concrete bases for sheds, summerhouses, hot tubs, greenhouses and garages, sized and finished to suit your structure. Every slab is set out accurately, poured to the right depth, and finished level so doors, frames and panels line up as they should. We also factor in drainage so water doesn’t sit around the edges.
Eastfields is a well-connected residential area with a mix of Victorian terraces, 1930s semis and modern developments across SW16 and CR4. Each property type brings different access and ground conditions, from narrow side passages to newer plots with made-up ground. Our team is based just 5 minutes away, so we can survey quickly and plan the best approach for your garden layout. That local familiarity helps us keep disruption low and the finish consistent.
We start with a site visit to confirm levels, intended load and where water will run. Then we excavate, install a compacted sub-base, add reinforcement where needed, and pour a durable slab with a neat edge detail. We keep you informed on curing times and when it’s safe to install your shed, summerhouse or hot tub. Homeowners choose us for tidy workmanship, clear scheduling and a result that doesn’t crack or rock underfoot.
Across the concrete bases Eastfields area, gardens can vary from compact plots to larger rear lawns, often with tight access and limited on-street parking. We plan deliveries and waste removal to minimise disruption and keep pathways protected. Ground conditions can include mixed made-up layers from older landscaping, so we prioritise proper excavation and compaction before pouring. Where needed, we’ll also advise on falls and drainage to suit local rainfall and garden layouts.

Costs depend on size, thickness, access and whether reinforcement is required. As a guide, small shed or greenhouse bases often start around £350–£700, while larger summerhouse or garage bases are commonly £900–£2,500+. Hot tub bases can fall in the £700–£1,800 range due to load requirements. Tight access in SW16/CR4, extra excavation, or spoil removal can affect the final figure.
Most standard shed or greenhouse bases are completed in a day, with larger slabs typically taking 1–2 days depending on excavation and sub-base depth. Concrete then needs time to cure; light foot traffic is often fine after 24–48 hours, but heavy loads or installing a hot tub may require 7–10 days. Weather, access, and the amount of ground preparation are the main factors that change timings.
In many cases, a concrete base for a shed, summerhouse or greenhouse is permitted development, especially when it sits within the rear garden and the structure meets height and boundary rules. However, restrictions can apply for listed buildings, conservation considerations, or if the base forms part of a larger outbuilding project. We’ll talk through your plans and, where needed, help you check Merton Council guidance before work starts.
We provide a 10-year warranty on our concrete base installations, covering workmanship issues such as settlement caused by inadequate preparation, poor compaction, or incorrect finishing. It also includes problems linked to reinforcement placement where specified. The warranty doesn’t cover damage from structural changes, extreme impact, or alterations made by others after completion. We’ll explain curing and loading guidance so your new base performs as intended.
We can build plain concrete slabs, reinforced bases for heavier loads, and bases with formed edges or shuttering for a crisp finish. For drainage, we can incorporate gentle falls, channel details, or perimeter gravel margins depending on your layout. Thickness is tailored to the structure—shed and greenhouse bases differ from hot tub or garage requirements. We’ll recommend the best option after checking access, ground condition and your chosen building footprint.
