Shed plans: how to pick one you can actually build

Reviewed 30 August 2026 · how we research

A shed is one of the most popular first big builds. The plan you start from decides how smoothly it goes. Here is what separates a usable shed plan from a frustrating one, and how to match a size to your yard and budget.

Building a wooden garden shed
8×10 ft ~80 sq ft 10×12 ft ~120 sq ft 12×16 ft ~192 sq ft
The three most-built backyard shed sizes, drawn to scale. Many areas need a permit above roughly 100–120 sq ft.

Common shed sizes

Most backyard sheds fall into a few footprints. An 8x10 holds a mower, tools, and a small bench. A 10x12 adds room for a workbench and wall storage. A 12x16 starts to work as a small workshop with space for machines. Check your local rules first - many areas allow a shed under 100-120 square feet without a permit, and going one size up can trigger paperwork.

Foundation options

  • Gravel pad with skids: cheapest, drains well, fine for smaller sheds on reasonably level ground.
  • Concrete blocks / deck piers: good on slopes, keeps the floor frame off the dirt.
  • Concrete slab: most work and cost, but the best base for heavy tools and a long-lived building.

What a good shed plan includes

  • A full cutting list and materials list with sheet-good counts, not just a drawing
  • Wall framing layouts with stud spacing and header sizes for the door and any windows
  • A roof plan with rafter or truss details and the correct pitch for your climate
  • Door construction details - the part most beginners underestimate
  • A fastener and hardware schedule

If a plan is only a picture and a rough size, expect to spend hours filling gaps. Plans with a proper cut list save money because you buy the right amount of lumber once.

Where a plan library helps

Shed and outbuilding plans are one of the stronger categories in the Ted's Woodworking library, and the bundled CAD viewer lets you stretch a plan to a size that fits your yard. As always, re-check the cut list after any change. If you only need one shed plan and want guaranteed detail, a single plan from an established publisher is also a fine route.

FAQ

What size shed can I build without a permit?

It varies by locality, but many areas exempt sheds under about 100 to 120 square feet. Confirm with your local building department first.

What is the cheapest solid shed foundation?

A compacted gravel pad under a skid frame. It drains well and suits smaller sheds on fairly level ground.

How many plans does a shed build need?

One complete plan, as long as it has a cutting list, framing layouts, and a roof detail. A plan that is just an illustration needs a lot of filling in.

What is the best shed roof style?

A simple gable or a single-slope lean-to roof. Both shed water well and are easy to frame. Match the pitch to your snow load.

How long does it take to build a shed?

A weekend or two for a small 8x10 with a helper, longer for a slab foundation or a larger footprint.

Do I need planning permission for a shed?

Rules vary. Many places exempt small sheds but restrict height, placement near boundaries, and any electrical work. Check locally.

What foundation is best on a slope?

Concrete blocks or deck piers that let you level the floor frame above the grade.

Should shed walls be framed 16 or 24 inches on centre?

16 inches for a sturdier wall and easier sheathing, 24 inches to save lumber on a light shed. Follow the plan.

What is the most-forgotten part of a shed plan?

Door construction. A square, braced, well-built door is what most beginners underestimate.

Can I insulate and wire a shed later?

Yes, if you frame with a cavity and leave access. Electrical work usually needs a permit and often a licensed electrician.
