A well-built concrete base makes the difference between a structure that lasts and one that shifts, cracks or holds water. We install bases for sheds, summerhouses, hot tubs, greenhouses and garages across SE3, with a clean, level finish. Whether you’re near Blackheath Common or closer to Blackheath Village, we tailor the slab size and spec to the load and layout. Expect neat edges, sensible falls and drainage that protects your garden.
Blackheath’s Georgian townhouses, Victorian villas and period conversions often come with mature gardens, side returns and shared access. That means base design needs to consider tight pathways, existing paving levels and neighbouring boundaries. We’re used to working around established planting and heritage-style landscaping so the finished base looks intentional, not like an afterthought. If you’re in Greenwich, Lee or Kidbrooke, we’ll match the base height to thresholds and patio levels for a seamless result.
We start with a site visit to confirm dimensions, ground condition and access, then set out and excavate to the correct depth. Sub-base, compaction, reinforcement and shuttering are done properly before we pour and finish the concrete to a true level or required fall. We keep disruption low, leave the site tidy, and provide clear aftercare guidance for curing. Homeowners choose us for reliable scheduling, transparent specs and workmanship backed by a 10-year warranty.
In the concrete bases Blackheath area, access can be tight and parking controlled, especially near The Paragon and around village streets. We plan deliveries, barrow routes and waste removal to keep disruption down and comply with local restrictions. Ground conditions can vary from firm made ground to softer pockets in older gardens, so we adjust excavation depth and sub-base build-up accordingly. We also consider boundary lines and neighbouring structures typical of Royal Borough of Greenwich/London Borough of Lewisham homes.

Costs vary by size, thickness, access and whether reinforcement and drainage are needed. As a guide, small shed bases often start around £450–£900, greenhouse or summerhouse bases commonly fall between £900–£1,800, and hot tub or garage bases are typically £1,800–£4,500+. Restricted access in SE3 can increase labour time. We’ll provide a detailed, itemised estimate after a site visit.
Most shed or greenhouse bases are completed in 1 day, while larger summerhouse, hot tub or garage bases usually take 2–3 days including excavation and sub-base work. Curing time matters: light foot traffic is often possible after 24–48 hours, but heavy loads and installations are best after 7 days, with full strength reached around 28 days. Weather, access and spoil removal can affect timings.
A concrete base for a garden building is usually permitted development, provided the overall structure meets height, boundary and use rules. However, restrictions can apply for listed buildings, conservation areas, or if you’re altering drainage or levels significantly. We’ll flag likely issues during the survey and can work with your plans for sheds, summerhouses or garages to keep within guidance. If needed, we’ll suggest when to check with the council.
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 covers defects arising from our reinforcement and shuttering installation. Normal wear, accidental damage, or movement caused by external factors (for example, tree roots or leaking drains) isn’t included. We’ll explain care and loading guidance to protect your base long-term.
We can build plain brushed concrete for grip, power-floated finishes for a smoother surface, or edged slabs for a crisp outline. Reinforcement options include steel mesh for heavier structures and thicker slabs for hot tubs or garages. We can also incorporate drainage falls, channel drains, or a raised slab where garden levels require it. We’ll recommend the best specification based on your structure, soil, and access in Blackheath.
