Concrete for Garden Room Bases

Order online, delivered across the Midlands, often next day.

From £212.66 per m³ (ex VAT)

Garden rooms typically carry more load than a shed, insulation, glazing, electrics and furniture all add up. C28/35 ready-mix at 100mm depth on a compacted Type 1 sub-base gives you a stable, frost-resistant slab that meets most permitted-development specifications. A typical 4×3m garden room base needs ~1.2m³; a 5×4m base needs ~2m³. Mesh (A142) recommended for any structure with significant glazing or partition walls.

Recommended Mix C28/35
  • C28/35 high-strength mix, supports modern garden-room builds
  • 100mm recommended depth on compacted sub-base
  • Suitable for garden offices, studios, treatment rooms and gyms
  • Saturday slots available subject to availability
