Concrete Bases & Shed Bases in Beckenham
Flat, square and ready for the shed.
As local shed base installers, we lay concrete bases in Beckenham BR3 for sheds, garden rooms, bike stores and outbuildings. In September 2026 we laid Mark's 8ft × 10ft reinforced shed base in Beckenham itself in a single day, and in Shortlands, a mile away, we used a concrete truck and pump for a shed base and new steps on a garden reached only through the house.

Your garden, considered
A shed is only as good as the base under it
A shed on old slabs, timber bearers or bare soil soon goes out of square: doors stick, the floor rots and water gets in. A concrete base gives it a flat, solid, dry footing. On Mark's job in Beckenham we dug out the old concrete and soil across the footprint, set the area out square and level against the existing patio, laid steel reinforcement mesh, then poured and brushed the concrete, all in one day.
On Beckenham's clay, which moves with the seasons, steel reinforcement mesh is worth having in a base. It helps the slab resist cracking and carry heavier loads, so the base stays flat under a heavy shed or a garden room full of furniture.
Bigger bases for garden rooms and offices need more planning: the size, the height above the garden, where cables and drainage go and how the concrete gets there. On sites without side access the concrete can come by truck and pump, as it did in Shortlands.

Materials & possibilities
Which base does your building need?
The base is sized and specified for what will sit on it. We confirm it at the survey.
Reinforcement, finish and curing
Steel mesh goes into the base before the pour so the slab acts as one piece rather than cracking into sections. The surface is levelled and given a brushed finish for grip, then the concrete is left to cure before the shed or building goes on top, so it reaches its strength first.

Porcelain patio and bullnose steps in Shortlands
Lucy's garden in Shortlands, a mile from Beckenham, climbs steeply from the house and every material had to come through the house. Using a concrete truck and pump, we poured a base for the existing shed, new steps and the patio base, then clad the steps and laid 25m² of porcelain, in one week for £9,250 including VAT.

Concrete bases laid across Beckenham BR3
We lay bases all over Beckenham, from Mark's garden in BR3 to Elmers End, Eden Park, Kelsey Park, Park Langley and Clock House, and next door in Shortlands and West Wickham. In Beckenham we have also built two pergolas and new fencing, so bases are often part of a bigger change to the garden.
We are based in Norbury, SW16, around 4 miles away, and work right across the Borough of Bromley.

Shed Bases in Beckenham: your questions
Still deciding? Tell us about your garden and we can talk through the next step.
Read our warranty termsHow much does a concrete shed base cost in Beckenham?
Mark's 8ft × 10ft shed base in Beckenham, reinforced with steel mesh and brushed, cost £1,820 including VAT, including breaking out the old concrete and taking it away. We quote your size after a free survey.
How long does it take to lay a shed base?
Mark's base was dug out, reinforced, poured and finished in one day. It then needs time to cure before the shed goes on.
Is concrete better than slabs for a shed base?
Concrete gives one solid, level slab that will not rock or sink, which matters on clay soil that moves with the seasons. Slabs on sand can shift, and the shed moves with them.
Do you put steel mesh in shed bases?
Yes. Mark's base in Beckenham had steel reinforcement mesh laid in before the pour, to help it resist cracking and carry heavier loads.
Can you lay a base for a garden room or office?
Yes. We built a garden room base in Brixton Hill as part of a five-day job, and a garden room base with a 20cm concrete retaining wall on a sloping site in Purley.
What if there is old concrete where the shed is going?
We break it out and remove it. On Mark's job the old concrete and soil were dug out across the whole 8ft × 10ft footprint before the new base went in.
Can you get concrete into a garden with no side access?
Yes. In Shortlands, with access only through the house, the concrete was placed using a truck and pump for the shed base, the steps and the patio base.
