If you need serious firewood storage, check out my latest 20 Cords 12×36 Firewood Shed Plans. This massive shed offers ample space to keep 20 cords of wood dry and organized. With these detailed plans, you’ll be building a robust and reliable shed in no time, perfect for preparing for those chilly winter months.

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

Assembling-the-floor-frames

Assembling-the-floor-frames

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. For this project we will need 3 identical frames like this one.

Fitting-the-skids

Fitting-the-skids

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 frames together with 2 1/2″ screws. Insert the screws every 12″ along the common joists.

Posts

Posts

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 and then remove the excess with a hammer and clean the surface with a chisel.

Attaching-the-posts

Attaching-the-posts

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.

Fitting-the-floor-slats

Fitting-the-floor-slats

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.

Top-plates

Top-plates

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.

Fitting-the-top-slats

Fitting-the-top-slats

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.

Rafters

Rafters

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

For the 20 Cords 12×36 Firewood Shed, plan on spending about two weekends to get this project completed, especially if you’ve got a helping hand. As for the cost, expect to spend around $2,500-$3,500 on lumber and framing materials, depending on your local prices.

Add another $500-$800 for roofing materials and hardware like screws and nails. So, all in, you’re looking at a total cost of approximately $3,000-$4,300 to build this impressive and spacious firewood shed.
