A solid base makes every garden project safer, neater and longer-lasting. From shed bases to greenhouse bases, we pour concrete that stays level and drains correctly. We regularly work around SE11, including routes near Oval tube station and Kennington Park where access can be tight. Your base is set out accurately, so doors, frames and fixings line up first time.
Oval has a mix of Georgian townhouses, Victorian terraces and mansion flats, often with compact rear gardens and side returns. That means materials handling, noise control and tidy working matter as much as the pour itself. We’re used to shared access, narrow passages and delicate paving that needs protecting. Homeowners across Kennington, Vauxhall and Stockwell choose us for clean edges and a finish that looks intentional, not improvised.
We start with a site visit to confirm levels, intended load and drainage falls, then specify the right depth and reinforcement. Ground is excavated, compacted and formed, with a sub-base where required, before we pour and finish to a true, flat surface. We keep you informed on curing times so you know when it’s safe to install your structure. Every job is completed to a consistent standard and backed by clear workmanship guarantees.
In the concrete bases Oval area, we often find mixed ground and made-up garden layers from older properties. Access can involve narrow side alleys and controlled parking near The Oval cricket ground, so we plan deliveries and waste removal carefully. We also factor in neighbouring boundaries and party walls common to terraces. Our approach suits the practical realities of concrete bases in London Borough of Lambeth, keeping disruption low while maintaining build quality.

Costs depend on size, thickness, access and whether reinforcement and a sub-base are needed. As a guide, small shed bases often start around £450–£900. Medium bases for summerhouses or greenhouses are commonly £900–£1,800. Heavy-duty hot tub or garage bases with thicker slabs and steel reinforcement can range from £1,800–£4,000+. We’ll confirm a range after checking levels, spoil removal and delivery access in SE11.
Most bases take 1 day for excavation, formwork and pouring, with an additional day if access is difficult or extra groundwork is required. Larger or reinforced slabs may take 2–3 days including sub-base installation and finishing. Concrete typically needs 24–48 hours before light foot traffic, and around 7 days before heavier loading, depending on weather. We’ll advise the safest installation date for your shed or hot tub.
A concrete base for a shed, summerhouse or greenhouse is usually permitted development, provided the overall structure meets height and location rules and you’re not creating a separate dwelling. However, restrictions can apply to listed buildings, conservation areas, and where drainage changes affect public sewers. In the London Borough of Lambeth we’ll flag any likely constraints, check relevant guidance, and recommend when to confirm details with the council before work starts.
We provide a 10-year warranty on workmanship for our concrete bases, covering issues such as poor compaction, incorrect levels and avoidable cracking caused by installation faults. The warranty assumes the base is used for its intended load and that curing guidance is followed before placing heavy items like hot tubs. We also document the specification (depth, reinforcement and drainage falls) so you have a clear record of what was installed.
We can build standard trowel-finished slabs for sheds and summerhouses, or heavier reinforced bases for hot tubs and garages. Options include thicker edges, mesh or rebar reinforcement, and falls to a soakaway for better drainage. If you want a cleaner look, we can form neat shuttered edges or set the base slightly below surrounding paving for a flush finish. We’ll recommend the best specification for your structure, soil and access.
