Garden shed plans

Before you start

You are viewing the imperial (feet, inches) version of this plan, original measurements have been converted to feet and inches with 1/32'' precision. See also Garden shed plans : Metric (millimetres/centimetres).

Build your own garden shed.

This DIY shed plan is a typical backyard design. It is designed as a garden shed but would also be suitable for other uses, e.g. a workshop.

The shed is a generous size, with over three square meters of internal floor space and enough head room for people of above-average height to stand up straight in.

Make sure you have a flat site for your shed. You can place it in the corner of a section but you need to be able to walk around it during construction.


You should have access to a range of typical DIY tools for this project, including a hammer, angle grinder, skill saw, hand saw, concrete trowel, cordless drill, and tape measure.

Here is your shopping list (suggested lengths of timber allow 5% wastage and off cuts):

  • 170' of dressed 2'' by 2'' framing timber*
  • 11' 6'' of rough sawn 50mm by 25mm timber
  • 108' of rough sawn 25mm by 75mm timber
  • 38' of rough sawn 1'' by 4'' timber (for door)
  • Approximately 24' of untreated 2'' boxing timber
  • Enough ready-mix concrete to make approximitly 9 cubic feet (refer to bag for volumes)
  • Two 5' 11'' sheets of corrugated iron with an effective coverage of at least 2' 5''
  • One 5' 11' sheet of corrugated PVC with effective coverage of at least 2' 5''
  • One 7' 2 1/2'' length of metal flashing to cap the roof
  • Two large door hinges and a door latch
  • One window, recommended size 1' 7 7/10'' (see The door and window)
  • Cladding materials (see cladding options)
  • 2'' flat head nails, 3'' jolt head nails, and roofing nails

*Dressing removes the surface of the timber so dressed timber dimensions are usually slightly smaller than the advertised dimensions. Our garden shed plan takes this discrepancy into account and minor adjustments will be needed if the framing timber you use doesn't measure 45mm by 45mm.  Always measure as you go as slight errors when cutting or different timber sizes will add up.
