4×8 Wood Shed Plans

This step by step diy project is about 4×8 wood shed plans. I have designed this 4×8 wood shed with a saltbox roof, so you can shelter the firewood and protect them from bad weather. This shed has not only an utilitarian role, but also a decorative function. 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.

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.

How to build a 4×8 wood shed



The first step of the project is to build the floor frame for the wood shed. Therefore, cut the joists for the shed from 2×6 lumber, at the dimensions shown in the diagram. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Place the joists every 16″ on center, making sure the corners are square and the edges are flush.

Fitting the skids

Fitting the skids

Select the location for the shed and level it up thoroughly. Fit the 4×4 skids to the ground before laying the floor shed. Use screws to secure the frame to the screws tightly, after aligning the edges flush. The skids will lift the floor from the ground and protect the joists from moisture.

Fitting the floor slats

Fitting the floor slats

Fit the 2×4 decking to the floor of the shed. Make sure you place 1″ block of woods between the slats so you create even gaps. Align the edges flush, drill pilot holes and insert 2 1/2″ screws, so you secure the slats into place tightly.



Build the back wall for the wood shed from 2×4 lumber. Cut the components at the right dimensions, using the information from the diagram. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center, making sure you align the edges flush and that the corners are square.



Build the front wall for the 4×8 wood shed from 2×4 lumber, as well. As you can notice in the diagram, you need to frame the opening, so you have an easy access to the firewood. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Build the header from 2 pieces of 2×4 lumber and one piece of 1/2″ plywood. Toenail the header to the studs and then fit the diagonal braces (45 degree cuts at both ends).



Building the side walls is a straight forward process, as all you have to do is drill pilot holes through the plates and insert 3 1/2″ screws into the studs.

Assembling the wood shed frame

Once you have assembled all the walls, you need to fit them on the floor of the shed. Align the edges flush and drill pilot holes through the bottom plates. Plumb the walls with a spirit level and insert 3 1/2″ screws to lock them into place tightly. Moreover, you need to lock the adjacent walls together tightly by drilling pilot holes and inserting 3 1/2″ screws.

Back wall - Siding

Back wall – Siding

Fit T1-11 siding to the back wall of the wood shed. Cut the sheet to the dimensions shown in the diagram and then attach them to the wall frame. As you can see in the diagram, you need to offset the panels 1 3/4″ from the top plates, so they can cover the end of the rafters, when we will install them. Use 6-8d nails to secure the panels, every 8″ along the framing.

Front wall - Siding

Front wall – Siding

Next, you need to fit the siding to the front of the wood shed. Make cuts so you can create the opening. Align the edges flush and insert 6-8d nails, every 8″ along the framing. Leave no gaps between the sheets for a professional look.

You need to take care of the finishing touches. Drill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint so you enhance the look of the shed and protect the components from decay.
