12x8 Sheds

12x8 (3658x2438mm) sheds are workshop territory: large enough for serious tool storage plus a workbench plus daylight, with floor space for a small motorbike or a rideon mower. Buy Sheds Direct, Robert Dyas and The Range between them cover £169-£2,238 across the range. At this size, planning permission becomes a real consideration, most 12x8 builds need permission if they sit in a front garden, near a boundary, or above 2.5m at the eaves. The build complexity also steps up: a 12x8 is a 2-day assembly with two helpers, not the half-day a 6x4 takes. Wall thickness: 16mm tongue-and-groove is the household standard at this size; 19mm is the longer-life build. Floor: 18mm tongue-and-groove softwood minimum, since the volume of stored equipment in a 12x8 is often heavier than smaller sheds. Most 12x8 sheds support double doors plus a side window for daylight. The grid below filters by material, door style and floor type.
