Response within 24 hours
If you’re adding a shed, summerhouse or hot tub in SE15, the base matters as much as the structure. We install concrete bases that stay level, shed water, and support heavy loads without cracking. Homeowners near Nunhead Green and Telegraph Hill Park choose us for tidy workmanship and clear communication. Every base is sized and finished to the manufacturer’s requirements.
Nunhead’s Victorian terraces, Edwardian houses and period cottages often come with long, narrow gardens and shared side access. That means materials handling and spoil removal need planning, not guesswork. We’re used to working around existing patios, mature planting and boundary walls common across Nunhead and nearby East Dulwich. Our team arrives prepared to protect paths, fences and neighbouring properties.
We start with a site visit to check levels, ground firmness and drainage routes, then set out the base with precise falls where needed. Sub-base, reinforcement and concrete depth are matched to the intended use—greenhouse, garage, or hot tub. You’ll get a clean, square edge, a smooth level finish, and a clear handover once cured. Many clients recommend us for reliable scheduling and professional aftercare.
Working across the London Borough of Southwark, we plan for Nunhead’s tight access, resident parking controls and period garden layouts. Ground conditions can vary from compacted made-ground to softer patches, so we don’t rely on a one-size approach. We also factor in drainage to avoid water tracking towards older brickwork and cellar areas. If skips or concrete deliveries need coordination, we arrange it to keep the job moving.

Costs depend on size, thickness, access and whether reinforcement is needed. As a guide, small shed bases often start around £450–£900, while summerhouse or greenhouse bases commonly fall between £900–£1,800. Hot tub bases are usually £1,200–£2,500 due to extra depth and steel mesh. Larger garage bases can range from £2,500–£6,000+. We’ll confirm after a site survey.
Most shed or greenhouse bases take 1 day on site, with curing time before loading. Summerhouse and hot tub bases typically take 1–2 days depending on excavation and sub-base work. Garage bases can take 2–4 days, especially if levels need building up or drainage is added. Access in Nunhead’s terraced streets, spoil removal, and weather can affect timings. We’ll give a clear schedule before starting.
In many cases, a concrete base for a shed, summerhouse or greenhouse is permitted development, provided the structure meets height and siting rules. However, restrictions can apply for listed buildings, conservation areas, or if you’re close to boundaries and neighbours. Drainage changes may also need care to avoid runoff issues. We’ll flag likely requirements during the survey and can help you check Southwark guidance before work begins.
We provide a 10-year warranty on workmanship for our concrete bases, covering issues such as poor compaction, inadequate thickness, or defects that cause movement or loss of level under normal use. It also covers problems arising from incorrect reinforcement installation where specified. The warranty doesn’t cover impact damage, unauthorised alterations, or exceptional ground movement beyond our control. You’ll also receive care guidance for curing and loading times.
We can install standard brushed concrete, smooth power-floated finishes, or a slightly textured surface for grip. Options include reinforced slabs with steel mesh, thicker edges for heavy loads, and integrated drainage falls where water needs directing away from buildings. We also build bases to exact manufacturer footprints for sheds, summerhouses, greenhouses and hot tubs. We’ll recommend the best thickness, finish and falls after assessing your garden and intended use.
