8×20 Firewood Shed – Free DIY Plans

by Ovidiu


This step by step diy project is about 8×20 firewood shed plans. This backyard shed can shelter up to 8 cords of firewood and it features a large opening to the front, for an easy access. This wood storage shed is built on a sturdy 2×4 framing, so it can withstand the elements. Make sure you read the local codes and make adjustments if necessary. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

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. See all my Premium Plans HERE.

Building a 8×20 firewood shed



First of all you have to assemble the floor frame for the firewood shed. Use 4×4 lumber for the skids and then attach 2×4 boards. Use a 1″ spacer between the boards to create even gaps. Align the edges flush and drill pilot holes. Insert 2 1/2″ screws to secure the boards into place tightly.



Use 2×4 lumber for the back wall frame. The back wall will be built using 2 frames. Cut the studs at 75 1/2″ and then secure them to the plates with 3 1/2″ screws or nails. Place the studs every 16″ on center and make sure the corners are square.



Assemble the side walls in the same manner described above.



Next, we need to build the sections for the front wall. Therefore, build the two side sections for the front wall. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.



Continue the project by assembling the middle section for the front wall.

Drill pilot holes and insert 3 1/2″ screws through the plates into the floor. Next, lock the adjacent wall together tightly with 3 1/2″ screws. Make sure the corners are right angled.
