12×24 Shed Plans – Free DIY Plans

 

This step by step woodworking project is about free 12×24 garden shed plans. If you are in need for a backyard workshop or for a large shed where you can store tools and furniture, I’ve got you covered with step by step 3D diagrams and instructions. PDF Download and Print friendly. The free DIY plans come with a full cut / shopping list. Make sure you read the local building codes, so you comply with the legal requirements. See my other DIY projects HERE ^[1].

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. See all my Premium Plans HERE ^[2].

How to build a 12×24 shed

The first step of the project is to frame the floor for the 12×24 shed. Cut the joists from 2×6 lumber. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Make sure the corners are square and align the edges flush. Measure the diagonals of the floor and make adjustments until they are perfectly equal. You can also use hangers to secure the joists into place.

Lay 4×4 skids on a level surface and then attach the floor frame. Make sure you place the skids equally spaced, so they can support the weight of the structure properly. Use rafter ties to lock the skids to the floor frame. In addition, drill pilot holes through the joists and insert 3 1/2″ screws into the skids.

Select the location for the shed and then remove the vegetation layer. Spread 2-3″ of gravel under the floor of the shed, so you can protect the components from moisture. I recommend you to use pressure treated lumber for the floor frame and for the plywood sheets.

Attach the 3/4′ plywood sheets to the floor frame. Align the edges with attention, drill pilot holes and insert 1 5/8″ screws every 8″ along the joists. Leave no gaps between the sheets for a professional result.

Assemble the front wall for the shed from 2×4 lumber. Make sure you use 2×6 lumber for the double header above the doors. Use 2×4 lumber for the double headers above and under the windows. After cutting all the components at the right dimensions, you need to assemble them together tightly. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs.  The studs are placed every 16″ on center.

You can adjust the size of the double door opening to suit your needs. In addition, you can make the necessarily modifications for fitting a garage door. The rough opening for the doors is 96″x80″. You can fit 2 ft x 3 ft windows to the openings, but in case you already have them and they have other dimensions, it is easy to make adjustments to the plans.

Building the double headers is a straight forward job. Since the actual thickness of 2x6s is 1 1/2″, we need to fit a piece of 1/2″ plywood between the beams, so we get a added thickness of 3 1/2″ long. Drill pilot holes through the beams and insert 2 1/2″ screws. Add glue to the joints and add a 1/2″ plywood piece for strength.

Frame the opposite wall using the same techniques described above. Assemble the frame on a level surface, such as the floor of the shed. Make sure you lock all the joints tightly together. Align the edges and place the studs every 16″ OC.

Last but not least, you need to assemble the side walls. We will start with the plain side wall. Just use the carpentry techniques described above to assemble the frame.

For the other side wall, you need to create an opening for a man door. The rough opening is 36″x80″, so you can install a standard door, as well. Notice the instructions from the 3D diagram, so you can space the studs properly and so you can cut all the components at the right dimensions.

Place the front and back walls to the floor of the large shed. Align the edges flush and plumb the with a spirit level. Use temporary braces to lock the wall frames to the floor of the shed. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the shed floor.

Fit the side wall frames to the floor of the shed. Align the edges flush, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Make sure you lock the adjacent walls together tightly. Drill pilot holes and insert 2 1/2″ screws to lock everything together tightly.

 

Fitting the siding sheets

Attach the T1-11 siding sheets to the back wall frames of the shed. Align the edges with attention and use 6-8d nails, every 8″, to lock them into place tightly. Leave no gaps between the sheets for a professional result.

Attach the T1-11 siding to the front wall of the large shed. Make a few cuts around the door opening and around the window openings. Smooth the edges with sandpaper, before locking them into place with 6-8d nails. Insert the nails every 8″ along the framing.

Check out PART 2 of the project to learn how to build the gable roof and the doors for this 12×24 backyard shed. You can easily use this shed as a workshop or for storing your bikes and other motorized toys.

This outdoor shed features a gable roof, double front doors to the front and a side door for easy access inside. You can easily frame a ramp so you can shelter inside larger objects. I have a full tutorial on how to build a shed ramp ^[8], as well. You can adjust the size of the windows to suit your needs, if you need more or less light inside the structure structure.
