10×12 shed plans: the numbers for a site check

The ridge runs the 12 ft way, parallel to the door wall, so half the roof drains off the 12″ eave above the door. The plan has no gutter, so add one on that eave if you want the drip off your doorway. The gable triangles are on the two 10 ft side walls, where the windows are. The back wall has no window, which leaves it free for shelves.

How the 10×12 gable shed goes together

The four skids are full 12 ft boards set 3′ 2 13/16″ on center. The 10 joists run 9′ 9″ between two 12 ft rims. The nailed floor frame weighs about 270 lb and racks if you lift it, so the plan has you build it in place on the skids.

How the walls go up

Each wall is framed flat on the deck, squared by its diagonals and raised as a bare frame by two people. The siding goes on after all four stand.

Never leave a raised wall unbraced, and never raise one in gusty wind. Get a second person for every lift.

What is on the 10×12 shed material list

The shopping list is grouped by build stage, in the stock length that wastes the least. These are the big lines:

• Foundation and floor: 4 pressure-treated 4×4 x 12 ft skids, 10 pressure-treated 2×6 x 10 ft joists, 2 pressure-treated 2×6 x 12 ft rims, 5 sheets of 3/4 in tongue and groove plywood, about 3.3 cubic yards of crushed stone and 5 pressure-treated 4×6 boards (one 8 ft, four 16 ft) for the pad frame.
• Walls: 2×4 studs 16 in on center, a doubled 2×8 door header, two doubled 2×6 window headers, 11 sheets of 5/8 in T1-11 and 2 pieces of Z-flashing.
• Roof framing: 12 2×4 x 14 ft boards for the rafters and fly rafters, 9 2×4 x 12 ft boards for the rafter ties and gable vent framing, a 2×6 x 14 ft ridge, 16 hurricane ties and 8 framing angles.
• Roof covering: 7 sheets of 7/16 in OSB, 1 roll of 15 lb felt, 7 bundles of 3-tab shingles and 8 pieces of drip edge.
• Fascia, soffit and gables: 2 T1-11 sheets for the gables, 2 sheets of 1/2 in plywood for the soffits, 1×6 fascia, 2 louvered 12 x 12 in gable vents and 2 aluminum 16 x 8 in under-eave vents.
• Door and windows: 2 new T1-11 sheets for the door leaves, 6 T-strap hinges, a handle and latch, 2 barrel bolts, 2 brush sweeps, 2 hold-open hooks, an aluminum threshold cap and 2 prefabricated 36 x 36 in windows.
• Hardware and finish: 33 lb of framing nails plus siding, sheathing and roofing nails, 6 ground anchors, 5 gallons of paint and primer, caulk and insect screen. The ramp has its own list.

The ridge and eave fascia boards are 14 ft long, so check that your truck or the yard’s delivery can carry them. Add 2 or 3 spare studs for bad boards, as the plan suggests. A cut list gives the length and count of every part, and a cutting plan shows which board each piece comes from. The 10×12 shed material list guide goes deeper into the numbers.

What you can fit in a 10×12 shed

The plan includes a to-scale drawing of one way to fill the floor, and it sells only what that drawing shows:

• A riding mower. A 42 in deck mower is 4′ 7 3/16″ wide and 5′ 10″ long and parks nose in. With both leaves open the clear width is about 5′ 11 1/2″, so it clears each side by 8 1/8″. A 48 in deck fits with its deflector raised, and a 54 in deck does not.
• Shelves. The drawing shows room for 12 in deep shelves on the back wall, in 2 ft runs.
• Other gear. A wheelbarrow (2′ 2″ x 5′ 0″) and two bikes with the handlebars staggered (2′ 6″ x 5′ 10″) fit in the same drawing.
• Behind the mower. The mower parks nose in, about 1″ off the back wall between the shelf runs, which leaves about 3′ 6″ of cross aisle behind its tail.
• Room in front. Keep 9′ 6″ clear and level, measured from the wall, for the ramp and one mower length, so a tractor lines up square.
• Headroom. The clear height from the deck to the underside of the top plates is 7′ 7 1/2″.

This is a medium load in a 120 sq ft room, not a workshop. If a rider is why you are buying, measure it first: width through the door, and length for the 9′ 6″ run in front.

The 10×12 double door: what changed

Earlier versions of this plan used a 5 ft (60 in) double door. This version has a 72″ double door in the 12 ft front wall:

• Opening: 72″ wide by 76 1/2″ tall, 3′ 0″ to 9′ 0″ from the left corner, under a doubled 2×8 header. That leaves 3 ft of wall on each side to hold the open leaves.
• Leaves: two, each 35 5/8″ wide and 6′ 5 1/4″ tall, cut from new T1-11 sheets because the siding cut from the opening is too short. Both swing out.
• Hanging: three T-strap hinges per leaf, a 1×2 stop under the header, a 1×2 astragal on the fixed leaf and barrel bolts top and bottom on that leaf. A hook and eye holds each open leaf against the wall, a 6 in one on the left leaf and a 4 in one on the right.
• Windows: the old single window is now two, one in each side wall.
• Ramp: a detachable 6′ 9″ wide ramp, 3′ 6″ out at 1:6, ends about 13/16″ below the deck, so there is a small lip, not a step.

How the 10×12 gable roof is framed

The roof is stick framed: 20 2×4 rafters 16″ on center plus 4 fly rafters, each cut from a 14 ft board (6′ 9 7/16″ long), against a 2×6 ridge 12′ 8″ long.

• No temporary posts for the ridge. A 2′ 2 13/16″ center gable stud on each end wall carries the ridge while you set the end pairs, held by braces.
• Ties. Eight 2×4 rafter ties, 10′ 0″ long, stop the walls spreading, and 4 collar ties keep the pairs together at the ridge in wind. Flat 2×4 ties also tie each gable wall plate to the first 2 rafter ties.
• Hurricane ties. 16 rafters get one at the plate, and the 4 end rafters take framing angles instead.
• Rakes. 2×4 lookout blocks carry a fly rafter on each rake for the 4 in overhang.
• Venting. Air comes in at a screened 16 x 8 in vent under each eave and at a 1 in screened slot over each frieze block, and leaves at two 12 x 12 in gable vents. The plan prints the arithmetic: 144.2 sq in of net free area, against 115 sq in from the common floor area / 150 rule of thumb, which is not a shed requirement.

Before you build a 10×12 shed

• Permits. Size, height and setback rules vary by town and HOA, and at almost 11 1/2 ft tall this shed may meet a height cap. Call 811 before you dig, and check your local permit office before you buy lumber; our shed permit checklist lists what to ask.
• Foundation. The plan uses skids on a gravel pad; shed foundation options compares others. Use ground-contact rated pressure-treated 4x4s (UC4A or higher).
• Anchors. An empty shed on skids can slide in a strong gust, which is why 6 ground anchors along the two outside skids are on the list. Heavy snow or high-wind areas may also need closer rafter spacing or larger rafters, so check your local permit office for your loads.
• Lumber care. Wood that stays wet decays faster, so keep the pile covered and off the ground (USDA Forest Products Laboratory Wood Handbook).
