This step by step diy project is about 14×18 gable shed plans. I have designed this rectangular shed so you can increase the storage space in your yard and to create a nice workshop. This shed with a gable roof features double front doors, a side door and a side window. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations.
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 14×18 shed
First of all, you need to build the frame for the floor. Cut the components at the right dimensions from 2×6 lumber. Align the edges flush and make sure the corners are square. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the joists. Place the joists every 16″ on center for a professional result.
Attach 4×4 skids to the floor frame. Place the skids equally spaced and use screws or hardware to lock them together tightly. The skids will lift the floor from the ground and this will protect the components from moisture.
Attach 3/4″ plywood sheets to the floor frame of the shed. Cut the sheets to the dimensions, show in the plans and in the cut list. Align the edges flush, making sure you leave no gaps between the components. Insert 1 5/8″ screws every 8″ through the sheets into the joists.
Building the shed wall frames
Build the front wall from 2×4 lumber. Make sure you assemble the header from 2×6 lumber and 1/2″ plywood. Align the edges with attention, drill pilot holes and insert 2 1/2″ screws into place. 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.
Build the back wall for the shed from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ for a professional result.
Build the side wall for the square shed using the same techniques described above. Center the top double plate to the side wall and lock it into place with screws.
Frame the other side wall for the shed from 2×4 lumber and 2×6 lumber for the double headers. You can adjust the size of the window opening, as well as of the door opening.
Assembling the shed frame
Fit the side walls frames to the shed floor and plumb them vertically. Make sure the corners are square and align the edges flush. Drill pilot holes through the bottom plates and insert 3 1/2″ screws.
Fit the front and the back wall frames to the floor of the shed. Use a spirit level to plumb the walls. Lock the adjacent wall frames together, by drilling pilot holes and insert 3 1/2″ screws.
Fitting the shed siding
Fit the T1-11 siding sheets to the side of the shed. Align the edges with attention, leave no gaps and lock them into place with 6-8d nails. Insert the nails every 8″ along the framing for a professional result.
Fit the siding panels to the side wall with window and door. As you can see in the diagram, you need to make a few cuts around the openings. Smooth the edges with sandpaper.
Last but not least, you need to attach the siding sheets to the front of the shed. Cut the T1-11 siding sheets for the front and lock them into place with 6-8d nails.
Fit the siding sheets to the back of the shed.
This 14×18 shed is ideal if you have a large garden and need space for storage or for a workshop. This shed is easy to build and you can modify it to suit your needs. Add windows if you need more light. Moreover, you can install a garage door instead of the double front doors.
Don’t forget to take a look over PART 2 and PART 3 to learn how to build the roof for the shed, as well as how to frame the double front doors. This square shed is large enough for your needs and it would make for a great workshop.
