This step by step woodworking project is about 4×20 firewood shed plans. You can build this lean to wood shed under 1000 usd and store up to 3 1/2 cords of firewood. This shed has a footprint of 4×20 and it features a large opening to the front, while the other 3 sides are enclosed with 1×6 boards. My woodworking plans come with step by step 3D diagrams, instructions and full CUT ad SHOPPING lists. See my other DIY projects HERE. Lots of PDF downloadable plans with premium features in the Store.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. This is a guest posts from MyOutdoorPlans.com

Building the firewood shed floor – 4×20
Building-the-floor-frame
Firstly, you need to assemble the floor frames for the firewood shed. Therefore, use 2×6 lumber for the joists and lay them 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 16″ on center and make sure the corners are square. Use at least 2 screws for each joint.
We will need two identical frames for the shed floor.
Fitting-the-skids
Next, select the location for the shed. Remove the top vegetation layer and level the surface thoroughly. You can use 4×4 skids or concrete blocks under the floor frame of the shed. We need them to lift the frame from the ground and thus, protect the joists from the elements.
Secure the skids to the floor frame with rafter ties and 1 1/2″ structural screws. Use at least 2 ties for each skid. In addition, lock the two frames together with 2 1/2″ screws.
Fitting-the-floor-slats
Continue the outdoor project by attaching the 2×4 boards to the floor frame. Align the edges and cut a piece of wood at 2 1/8″ to use it as a spacer. Drill pilot holes and insert 2 1/2″ screws to lock the boards into place.

Building-the-posts
Use 2×6 lumber for the front and back posts, and 2×4 lumber for the side posts. Cut the posts at the dimensions shown in the diagram. Add glue to the joints, drill pilot holes and insert 2 1/2″ screws to assemble the corner posts. Make sure you align the edges flush, before inserting the screws.
Fitting-the-uprights
The next step of the project is to attach the corner posts to the floor of the shed. Align the edges flush and use a spirit level to plumb the posts before inserting the screws into the floor. Drill pilot holes and insert at least two 3 ” lag screws for each joint. Also, notice the middle posts that are mean to support the top beams.
Fitting-the-top-beams
Use 2×8 lumber for the top support beams. Drill pilot holes through the side posts and insert 3 1/2″ screws into the top beam. In addition, notice the structural connectors used to lock the into place the top beams. You need L ties to secure the beams to the side front and back posts. Of course, you need to insert 1 1/2″ structural screws to lock the ties into place.
Also, you need to set T ties to lock the middle posts to the supports beams.
Building the lean to roof for the wood shed
Building-the-rafters—4×10-wood-shed
Use 2×4 lumber for the rafters of the lean to wood shed. Mark the cut lines and get the job done with a circular saw. We need the birdsmouth cuts to lock the rafters properly to the support beams. Also, notice the generous overhangs to the front and back of the firewood shed.
Fitting-the-rafters
Fit the rafters to the top of the shed and place them every equally spaced. Use rafter ties and 1 1/2″ structural screws to lock the rafters to the top support beams.
Side-slats
Use 1×6 slats for the sides of the firewood shed. Align the edges flush and place a 2 1/2″ wood block between the slats. Insert 1 5/8″ screws to lock the slats into place tightly.
Fitting-the-back-wall-slats
Fit the slats to the back of shed, as well. Use 1 5/8″ screws to secure the slats into place.
Fitting-the-purlins
We will cover the roof for this lean to shed with metal sheets, therefore fit the 1×4 purlins to the rafters. Align the edges and insert 1 5/8″ screws to lock the purlins into place. Notice the 6″ overhangs on both sides of the woodshed.
Fitting-the-roofing
Fit the metal roof sheets to the top of the shed. Use the appropriate screws to secure the metal roof sheets to the purlins. Using metal sheets is a cost effective method to protect the firewood from the elements.
Finishing touches for the woodshed

Last but not least, take care of the finishing touches. Apply a few coats of paint / stain over the components to enhance the look of the shed and to protect the components from decay.

This is a beautiful shed that will help you store 3 1/2 cords of wood efficiently and on a super affordable budget. The wood storage shed has generous overhangs on all sides and it features a basic lean to roof with metal sheet roofing. Notice the overall height of the shed is under 8 ft. If you want to build a large shed that can hold up to 9 cords of wood, you should take a look over these plans.
