This step by step diy project is about 12×12 shed plans. I have designed this beautiful 12×12 shed with a 4′ front porch. The total size of the floor, including the porch, is 12×16. This small shed has a front door and double side doors, for an easy access, even with large objects. 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.

How to build a 12×12 shed with porch
The first step of the project is to build the floor frame. Cut the components from 2×6 lumber, as shown in the diagram. Place the joists every 16″ on center, for a professional result. Check if the corners are are square, drill pilot holes through the rim joists and insert 3 1/2″ screws.
Select the location for the shed and level the surface thoroughly. Remove the vegetation layer and make sure you comply with the local building codes. Fit the skids on the location. Place the floor frame and then use rafter ties to lock the skids to the frame. Align the edges with attention for a professional result.
Fit the 3/4″ plywood sheets to the floor frame and align the edges with attention. Insert 1 5/8″ screws every 8″ along the joists. Leave no gaps between the sheets for a professional result.
Build the back walls of the shed from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Align the edges and make sure the corners are square. Alternatively, you could use framing nails and a framing gun.
Continue the project by assembling the front wall frame. Use 2×4 lumber for the front wall frame. Use 2×6 lumber and 1/2″ plywood for the double door header. Use 1/2″ plywood and 2×4 beams for the window headers. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Make sure the corners are square and align the edges flush. You can adjust the size of the door and window openings to suit your needs.
Build the side wall for the shed using the same techniques described above and the information from the diagram.
Build the opposite side wall using the diagram shown above. Cut the components from 2×4 at the dimensions shown in the diagram. You can make the double doors wider, if you need even more space for an easy access.
Fit the wall frames to the floor of the shed. Align the edges with attention and plumb the walls with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together tightly using 3 1/2″ screws.
Build the posts for the front porch from 4×4 lumber. As you can see in the diagram, you need to make some notches to the corner posts. Use a circular saw to make the notches and remove the excess with a chisel.
Fit the posts to the floor frame, as show in the diagram. Plumb the posts with a spirit level, drill pilot holes and insert 3 1/2″ lag screws.
Use 4×4 lumber for the top plates. As you can easily notice in the diagram, you should make notches to the beams using a circular saw. Make parallel cuts to the marked areas and then get the job done with a chisel. Clean the recess with sandpaper.
Fit the 4×4 plates to the top of the shed, as shown in the diagram. Make sure the edges are flush and check if the corners are square. Insert 5″ screws to lock the plates into place tightly.
Fit the T1-11 siding sheets to the plain side of the storage shed. Use 6-8d nails to secure the sheets into place, every 8″ along the framing.
Fit the other panels to the opposite side of the shed. Make cuts to the panels so you can fit them around the door opening.
Fit the sheets to the front of the shed. As you can see in the diagram, you need to make the cuts so you create the door opening.
Fit the T1-11 siding panels to the back of the shed. Align the edges with attention and leave no gaps between the sheets. Insert 6-8d nails every 8″ along the framing.
Make sure you check out PART 2 of the shed, where I show you how to build the lean to roof.
Take a look over PART 2 and PART 3 of the project, so you learn how to build the double doors and the roof. I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project. See all my shed projects HERE.
