If you’re planning a new shed, summerhouse or hot tub, the base needs to be flat, strong and properly drained. We install concrete bases across CR0, including homes near Addiscombe tram stop and Ashburton Park. Every slab is set out accurately so doors open cleanly and frames stay square. The result is a foundation that won’t dip, crack prematurely or hold standing water.
Addiscombe’s gardens often sit behind Victorian terraces, Edwardian houses and 1930s semis, where access can be tight and levels can vary. We’re used to working with side returns, narrow pathways and stepped lawns common around East Croydon and Shirley. Our team measures falls, checks ground stability and designs the base to suit your structure’s footprint and loading. That means fewer future issues, whether you’re fitting a greenhouse or a larger garage base.
We start with a site visit, confirm dimensions, and advise on thickness, reinforcement and drainage. Sub-base preparation is never rushed: we excavate, compact, and install edging/shuttering for crisp lines and a true level finish. You’ll get clear communication on timings, curing, and when it’s safe to install your building. Local homeowners choose us for tidy workmanship, dependable scheduling and robust results.
In the London Borough of Croydon, garden ground can vary from firm subsoil to made-up areas from older landscaping. Around Woodside and Croydon, we often encounter mixed levels and limited on-street parking, so we plan deliveries and barrow routes carefully. We also account for neighbouring boundaries and shared access typical of period terraces. Our approach keeps disruption low while ensuring the base is structurally sound.

Costs depend on size, thickness, access and whether reinforcement or extra excavation is needed. As a guide, small shed bases often start around £350–£700, while larger summerhouse or greenhouse bases are commonly £800–£1,600. Reinforced hot tub bases typically range from £900–£2,000+. If access is tight or spoil removal is significant, costs can increase. We’ll confirm a tailored price after a site visit.
Most shed or greenhouse bases take 1 day on site, with larger summerhouse or garage bases usually 1–2 days depending on excavation and sub-base work. Concrete then needs curing time before loading—often 48–72 hours for light foot traffic, and around 7 days before installing heavier structures (longer in cold weather). Access, weather, and drainage requirements can all affect the schedule.
In many cases, a concrete base for a garden building is permitted development, especially when it’s within your garden and not used as a separate dwelling. However, rules can change if you’re close to boundaries, altering levels significantly, or installing a large outbuilding or garage. Drainage and surface water management may also be relevant. We’ll flag any concerns and can help you check Croydon guidance before work begins.
We provide a 10-year warranty on workmanship for our concrete base installations. This covers issues arising from installation faults such as poor compaction, incorrect levels, or inadequate preparation leading to avoidable movement. It doesn’t cover damage from external causes like tree root heave, flooding, or heavy impacts beyond the base’s design load. We’ll also advise on correct curing and installation to protect your warranty.
We can build standard brushed-finish slabs, smooth power-floated finishes (where suitable), and reinforced bases using steel mesh for heavier loads. Options include thickened edges, shuttered borders for clean lines, and falls designed for drainage away from buildings. For hot tubs, we’ll size the slab and reinforcement to the manufacturer’s load requirements. We’ll recommend the best specification based on your structure, ground conditions and access.
