12×30 Firewood Shed Plans – 15 Cords Storage

by Ovidiu


This step by step diy project is about 15 cords firewood shed plans. This is a step by step DIY tutorial on how to build a large 12×30 firewood shed that can hold up to 15 cords of firewood. The wooden structure features a lean to roof and enclosed walls on three sides. In addition. I framed a small area inside the shed where you can store tools or garden equipment. See the rest of my firewood shed free plans HERE. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Premium Plans for this project available in the Shop.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build a large firewood shed



The first step of the project is to assemble the frame for the floor. Cut the joists at the dimensions shown in the diagram and lay everything on a level surface.

Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Place the joists every 24″ on center. Measure the diagonals and adjust until they are equal.



Assemble the other floor frame, as shown in the diagram. If you don’t have access to 18 ft long 2x6s, then you can simply build two frames, one 12 ft long and the other one 6 ft long.

Place the joists every 24″ on center. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the joists. Align the edges flush and measure the diagonals of the frame. Make adjustments until they are equal.



Use 4×4 lumber for the skids. It would be a great idea to use pressure treated lumber. Fit the skids under the floor frame, and use rafter ties and 1 1/2″ structural screws to lock them together tightly. Use 2 rafters for each skid.

Join the two separate frames together with 2 1/2″ screws. Insert the screws every 12″ along the common joists. Use a spirit level to check if the floor is perfectly horizontal.



You need 4×4 lumber for the shed posts. Use a saw to make the cuts to the posts. Mark the cut lines to the posts, make parallel cuts inside the marked areas and then remove the excess with a hammer and clean the surface with a chisel.

We need the recesses to be able to set the posts to the floor frame properly.



Attach the posts to the floor frame as shown in the diagram. Drill pilot holes and insert 3 1/2″ lag screws to lock the posts to the floor frame. Plumb the posts with a spirit level and double check if they are secured properly into place.



Use 2×6 lumber for the floor slats. Fit the slats to the floor frame and fit pieces of 3/4″ plywood between them, to create even gaps.



Use 4×8 lumber for the top beams. Use a circular saw to make notches to the beams, as described in the diagram. Make parallel cuts inside the marked areas and then clean the recess with a hammer and a chisel.



Fit the beams to the top of the posts. Leave 12 3/4″ overhangs on both sides of the firewood shed. Use post to beam connectors to secure the posts to the top beams. Insert 2 1/2″ structural screws to secure the beams to the posts.



Use 4×4 lumber for the braces. Cut them at 36″ making sure you make 45 degree cuts to both ends of the braces. Plumb the posts vertically and then secure them braces into place with 5 1/2″ screws.



Drill pilot holes before inserting the screws to prevent the wood from splitting.



Use 2×6 lumber for the rafters.  Mark the cut lines to the beams and get the job done with a circular saw.



This sturdy firewood shed is both practical and it features an elegant design, so you can save time and store the firewood efficiently. The lean to shape of the roof keeps the costs down but it also makes it easy to build by everyday DIY-ers.

If you look closely to my design this shed uses large beams that offer excellent support for winds, snow and other elements.

Notice the storage area inside the large firewood shed. You can even add a door, if you want to keep the items secure. As you can see the possibilities are endless and the adjustability is the strong point of this design.

This is a very large firewood shed that can hold up to 15 cords of firewood. This lean to structure is roomy, it features a separate storage area, but it will come at a price. If you want to build this, you need to be prepared to pay for the materials. However, compared to buying a kit, this project will cost much lesser.
