Shed Bases in Orpington: Only as Good as the Base
On Orpington's clay soil, a shed without a proper base will sink and rot within seasons. We compare paving, concrete and timber bases for BR5 and BR6 sheds and garden rooms.

A shed is only as good as its base
It's the most overlooked part of a garden building — and on Orpington's clay soil, a poorly founded shed will sink, twist and rot within a few seasons. Doors stop closing, floors bounce, and the building you expected to last a decade is fit for the skip in three years. A level, properly built shed base is a small cost that adds years to the life of whatever sits on it.
Which base suits your Orpington garden?
- Paving slab base — clean, level and well-drained; a great all-rounder for sheds and summerhouses across BR5 and BR6.
- Concrete base — the strongest option, ideal for heavier garden rooms, workshops or buildings on soft ground.
- Timber bearer frame — a cost-effective raised base that suits lighter sheds and keeps the floor clear of the ground.
- Plastic grid bases — quick to lay and porous, useful for lighter buildings on well-drained plots.
We'll advise on the right base for your building size, ground and budget — not a one-size-fits-all answer.
Built level, with drainage considered
Every Orpington shed base we build is set level and square, with drainage considered, so the building sits dry and true for the long term. On clay, that means proper ground preparation — excavation, levelling and a compacted base — rather than slapping slabs straight onto soil that shifts with the seasons.
Base and shed in one sequence
Because we build the patio, fencing and structures too, we can site your shed to sit with the rest of the garden — aligned to paths, screened by planting, or set as a garden room at the end of the lawn. We handle the ground preparation, base construction and shed installation in one sequence, so you deal with a single contractor from bare ground to finished building.
