A shed is only as good as the base beneath it, especially after a wet winter. We install shed bases for homeowners across BR1, including near Downham Fields and the Downham Health and Leisure Centre. Whether you’re replacing an old base or starting from scratch, we create a firm, level platform that helps prevent rot, movement and sticking doors. All sizes are catered for, from compact bike stores to large workshops.
Downham’s established residential estate includes 1920s cottage plots, 1930s semis and post-war housing, often with long gardens and side access. These layouts can bring challenges such as narrow gates, shared boundaries and uneven ground at the back of the plot. Our shed bases in the Downham area are planned to suit each garden’s levels and access, with clean edges and a practical finish. We also work regularly around Catford, Grove Park and Bellingham for matching property styles.
We start with a site visit to check levels, soil condition and where water currently sits after rain. Then we excavate, install the right sub-base, compact properly and finish to accurate levels for your shed footprint. We keep disruption low, protect surrounding paving and lawns, and leave the site tidy. Homeowners choose us for straightforward advice, clear options and consistent workmanship backed by a 10-year warranty.
Gardens in the London Borough of Lewisham can vary from firm, compacted ground to softer areas that hold water. We factor in fall, drainage and where downpipes discharge, so the base performs through heavy rain. Access is often via side passages on 1930s semis, so we plan material handling and waste removal accordingly. If parking is limited on residential streets, we schedule deliveries to minimise disruption.

Costs depend on size, base type and how much excavation is needed. As a guide, small paving slab bases often start around £350–£750, while larger slab bases can be £800–£1,500+. Concrete bases typically range from £700–£1,800+ depending on thickness and reinforcement. Plastic grid bases can be cost-effective for lighter sheds, usually £450–£1,200+. We’ll confirm after a site check in BR1.
Most shed bases are completed in 1 day, especially paving slab, plastic grid or timber bases. Larger excavations, difficult access, or a thicker concrete pour can take 2–3 days, particularly if spoil removal is substantial. Concrete may also need curing time before the shed is installed, typically 24–72 hours depending on conditions. Weather, ground softness and hidden obstructions can affect the schedule.
In many cases, a shed base and shed are permitted development for UK homes, provided size, height and location rules are met. However, restrictions can apply for listed buildings, flats/maisonettes, or if you’re close to boundaries with unusually large structures. Surface water rules may also matter if you’re creating an impermeable area. We’ll talk through the likely requirements and advise if you should check with Lewisham Council before work starts.
We provide a 10-year warranty on workmanship for shed bases we install, covering issues such as settlement caused by inadequate preparation, poor compaction, or incorrect levels. It also covers defects in installation that lead to movement or instability under normal use. The warranty doesn’t cover damage from third-party alterations, extreme ground movement beyond reasonable control, or shed defects. We’ll explain care and loading limits for your chosen base type.
We install concrete bases for maximum strength, paving slab bases for a neat, modular finish, plastic grid bases for quick-draining, lighter structures, and timber bases where a raised, ventilated platform is preferred. The best choice depends on shed weight, intended use (storage vs workshop), drainage, and ground conditions. We’ll measure your shed footprint, check levels, and recommend the most practical build-up for longevity and a clean finish.
