Shed Bases & Garden Buildings in Dulwich

A shed is only as good as its base — and on London's clay soil, a poorly founded shed will sink, twist and rot within a few seasons. Rubin Constructions builds level, durable shed bases and garden-building foundations across SE21 — across SE21, from paving-slab and concrete bases to timber bearer frames for sheds, garden rooms and summerhouses. Every base is set level, with drainage considered, so your building sits square and dry for the long term.

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. With 4.9/5 from verified reviews and free site visits across Dulwich, your shed base is built to the same standard as our patios.
