In Canada (2.44 m × 3.05 m shed)

Set to Canada, the Sheet works the job out again for Ontario: metric sizes, bag sizes, the frost depth and the code notes. It doesn't just convert feet to meters. The first lines:

1.5 m³ delivered, Crushed stone base, bulk: 3.05 m × 3.66 m (the shed + 305 mm on every side) × 102 mm, +20% because it compacts = 1.36 m³ — about 2.5 tonnes.
1 roll, Landscape filter fabric: 11.1 m² + 10% for laps ÷ 13.9 m² a roll: keeps the gravel out of the soil.
3 boards, Pressure-treated 4×6: 3 skids the length of the shed (3.05 m), at both sides and the middle; ground-contact treated.
9 boards, Pressure-treated 2×6: 9 joists 406 mm on center along 3.05 m (8 spaces + 1), each 2.36 m between the rims.
2 boards, Pressure-treated 2×6: Two rims, the length of the shed (3.05 m), nailed to the joist ends.
3 sheets, Subfloor 19 mm tongue-and-groove, 4×8: 7.4 m² + 5% ÷ 3.0 m² a sheet. Treated plywood or OSB rated for floors, long edges across the joists.

The steps, in order

Check first: the size and height limits and the setbacks from your lot lines. Call 811 (NJ One Call) at least 3 full business days ahead and wait for the utility markings.
Pad: strip the sod 1 ft past the shed on every side, lay landscape fabric, then level and compact 4″ of gravel in two lifts.
Floor: skids level on the gravel, the floor frame square — equal diagonals — joists 16″ on center, the subfloor glued and nailed.
Walls: frame each wall flat on the floor — plates, studs 16″ on center, kings, jacks and headers at the openings — then raise it with two people, plumb it, brace it, and nail the second top plate across the corners.
Rafters: cut one pattern pair, test it on the walls, cut the rest; the ridge board, rafters 24″ on center with a tie across every pair at the plates, a hurricane tie at every rafter, gable studs to the rake.
Roof deck: ½″ sheathing from the eaves up, joints staggered, H-clips between the rafters; fascia and rake boards.
Siding: T1-11 plumb from 1″ below the floor frame, Z-flashing at every horizontal joint; cut the door opening out of the panels and keep the piece for the door; corner boards and casing.
Roofing: drip edge on the eaves, underlayment, drip edge over it on the rakes, starter, shingles with 4 nails each, the ridge cap.
Doors: build the leaves from the cut-out panel on a 2×4 frame with a Z-brace, hang them on T-hinges, add the latch and the cane bolt; windows into flashing tape, the sill first.
Paint: caulk the trim joints, prime the siding and trim, then two coats of exterior paint.

Carpentry & framing · Sheet S-41 · 04Mistakes and how the math works

Mistakes and how the math works

Mistakes that cost a callback or a second trip

An out-of-square floor: Every wall and rafter after it fights the error. Measure both diagonals and make them equal before the subfloor goes down.
Untreated wood near the ground: It rots in a few years. Skids, beams and the floor frame are treated; keep the siding off the gravel.
No Z-flashing at the joints: Water runs into a horizontal panel joint and rots the edges. Flash every one.
Leaving out the rafter ties: The roof pushes the walls apart and the ridge sags. A tie across every pair, at the plates.
Building in the setback: Too close to the lot line, or too big for the permit rules, can mean moving it. Check before you dig.

What the calculator assumes

Shed 8′ wide (the door end) × 10′ deep = 80 sq ft; walls 8′ 1-1/8″ to the top plates (92⅝″ precut studs).
The floor about 9-3/4″ above the ground (4×6 skids laid flat, 2×6 joists, ¾″ floor); the peak about 11′ 4-1/4″ above the ground.
Studs and joists 16″ on center, rafters 24″; 2×6 rafters and 2×6 joists are typical shed sizes, not from a span table.
Lumber cut from 8–16 ft stock: equal pieces in the length that wastes least, short pieces from the offcuts.
Door: two leaves built from the siding, 60″ × 7′ 4-5/8″ opening; windows about 18″ × 27″.
Shingles: 3 bundles a square, starter about 105 ft and cap about 30 ft a bundle (the roofing Sheet’s figures).
Paint: about 250 sq ft/gal a coat on rough T1-11, one coat of primer and two of paint.

Carpentry & framing · Sheet S-41 · 05Code, permits and safety

Code, permits and safety

The Sheet sets its code notes for the job's state or province. These are New Jersey's and Ontario's; the code reference has more. Always confirm with your building department.

Call 811 first — it’s the law: In New Jersey, call 811 (NJ One Call) at least 3 full business days before digging. Free. Wait for the utility markings.
Construction permit needed: New Jersey exempts sheds only up to 200 sq ft and 10 ft tall (N.J.A.C. 5:23-2.14(b)8); this one is 80 sq ft and about 11′ 4-1/4″ to the peak. Ask your town’s construction office — or lower the walls or the roof pitch to stay under 10 ft.
Click Before You Dig: Before you dig, request a free utility locate from Ontario Dig Authority (ontariodigauthority.ca) at least 5 business days ahead, and wait for the markings.
No building permit for this shed: Ontario needs no building permit for a detached, one-storey storage shed of 15 m² or less with no plumbing (Building Code, Division C, 1.3.1.1); this one is 7.4 m². Zoning by-laws still set where it goes. Confirm with your building department.

Each line's math is in the table above. Put in your own sizes in the shed calculator and every line is counted again.

How long does it take to build a storage shed, and can I do it myself?

About 47 to 73 hours for the worked example, in 10 steps. StudSheet stamps it DIY OK: you can do this.

What tools do I need to build a storage shed?

32 in all. The must-haves start with circular saw, speed square, framing square, tape measure (25 ft), carpenter's pencil, chalk line. On the Sheet you mark each one as owned, to buy or to rent.
