A well-laid base is what keeps a shed, greenhouse or hot tub stable for years, not months. We install concrete bases across Woolwich, including around Royal Arsenal and Woolwich Town Centre. Every slab is set out accurately, poured to the right depth, and finished level so your structure fits properly. If drainage is a concern, we design falls and edge details to move water away.
Woolwich homes range from Victorian terraces to converted arsenal buildings and modern apartments, and each brings different access and ground challenges. In Plumstead and Charlton, gardens can be long and narrow, so we plan barrow routes, waste removal and tidy working areas. For newer developments, we’re used to shared access points and strict site rules. Our approach is tailored so the base suits the structure and the property, not the other way round.
We start with a site visit, measure-up and a clear written specification: size, thickness, reinforcement and finish. Ground is excavated, a compacted sub-base installed, then we pour and float-finish the concrete for a clean, level surface. We keep you informed on curing times and when it’s safe to install your shed, summerhouse or hot tub. Homeowners choose us for reliable scheduling, neat workmanship and a 10-year warranty on our base installation.
The concrete bases Woolwich area often need extra care with access, especially near SE18 flats and busy roads by the Woolwich Ferry. We plan deliveries and mixing to suit parking restrictions and minimise disruption. Ground conditions can vary between made ground around regeneration sites and older garden soils, so we adjust excavation depth and sub-base build-up accordingly. We also work with sensible drainage details to suit patios, lawns and tight side returns.

Costs depend on size, thickness, access and whether reinforcement is needed. As a guide, small shed bases often start from around £350–£700, while larger summerhouse or greenhouse bases are commonly £800–£1,600. Hot tub and garage bases with thicker concrete and steel reinforcement can range from £1,500–£4,000+. We’ll confirm a tailored price after checking levels, ground and access in SE18.
Most shed or greenhouse bases are completed in 1 day, with larger summerhouse bases typically taking 1–2 days depending on excavation and spoil removal. Hot tub or garage bases can take 2–3 days if deeper dig, reinforcement and drainage are required. Concrete needs curing time too: light foot traffic is often fine after 24–48 hours, but placing heavy loads may need 7–14 days depending on weather.
In many cases, a concrete base for a shed, summerhouse or greenhouse is permitted development, provided the structure meets height and location rules. However, restrictions can apply for listed buildings, conservation areas, flats, and some converted developments. Drainage changes and hardstanding near boundaries can also need consideration. We’ll talk through the rules, recommend best practice, and can help you check Royal Borough of Greenwich guidance before work starts.
Yes. Our concrete base installation comes with a 10-year warranty covering workmanship issues such as settlement due to poor sub-base preparation, incorrect levels, or cracking caused by installation faults. It also covers failures related to specified reinforcement and edging details. Normal wear, accidental damage, and movement caused by external factors (like tree roots or underground leaks) aren’t included, but we’ll always advise on prevention during the survey.
We can build plain brushed concrete, smooth float finishes, or a slightly textured finish for grip. Options include reinforced slabs (steel mesh or rebar), thicker pads for hot tubs, and perimeter thickening for heavier structures. We can also add drainage falls, gravel margins, or a raised edge to keep timber frames off standing water. We’ll recommend the right specification based on your structure, ground and access.
