6×12 Firewood Shed Plans & Instructions
Step 1 – Foundation and Support
At first, select an appropriate site for the firewood shed foundation, placing the backside of the firewood shed against a structure helps to increase protection from strong wind and rain.
Once you select a site, cut seven 4×4 lumbers to 6′-0″ length, these will be used as the skid foundation. Then, cut two 1×6 lumbers to 12’-0″, for perimeter floor joists. Arrange the 4×4 skids 24″ O.C. as illustrated in the diagram below, drill pilot holes into the joists and secure with 3 1/2″ screws.
Next, cut three sets of 4×4 lumbers to 7′-8 1/2″ and 6′-3 3/8″ to be used as the primary studs. Then, position the 4×4 studs directly on top of the skid foundation, with the longer pieces in the front of the shed.
The floor deck is made up of 11 2×4’s in 12′ length, placed evenly across the foundation, with about 1 3/8″ gap in-between each lumber. Cut out 3 1/2″ x 3 1/2″ corners to fit into the 4×4 studs neatly. Then, drill pilot holes and secure in place with 3 1/2″ screws, directly attaching to the 4×4 skid below.
Step 2 – Rafters and Roofing
There are three primary rafters attached to the studs, which holds up the entire roof structure. These rafters are made up of six 2×6 lumbers cut to 8′-1″ length, secured to the 4×4 studs with 3 1/2″ screws. This will create a roof pitch of 3/12.
Then, attach two 12′-3″ 1×6’s to the front and back of the rafters, as illustrated below:
Once the rafters are in place, we will start to assemble the roof purlins. First, cut two 2×4’s to 8′-1″ for the side purlins, these will help to create overhangs. Then, measure and cut out seven 2×4’s to 12′-9″ in length, space these out evenly at 16″ O.C. Secure to the side purlins and on top of the rafters with 3 1/2″ nails.
Tip: it’s easier to build the entire purlin structure on the ground and then raise in place on top of rafters.
Next, cut and attach the corrugated metal roof panel on top of the purlins. Align the roof panel edges with the purlin perimeter edges to get a professional look, trim or sand away extra metals. You’ll need 105SF to cover the entire shed roof, these panels usually come in 3′ x 8 ‘ sized sheets.

Step 3 – Exterior Sidings
Finally, we will complete the 6×12 firewood shed by adding exterior side panels. You’ll need to cut 16 1×6’s to 6′, and eight 1×6’s to 12′-1 1/2″. Starting from the bottom, position the 1×6’s in place and secure with 2″ nails to the stud. Work your way up, leave approximately a 2″ gap between each panel.
Tip: you can use T1-11 plywood panels if you want to increase enclosure, it also takes less effort to install.
Lastly, check to make sure all the pieces are properly secured in place before loading in the firewood. You can also install a tarp to the front side of the shed during winter seasons to block out snow and rain.
Well done! You’ve just completed building your very own 6×12 firewood shed!
The 6×12 firewood shed is large enough to hold 3 full cord of wood.
