This step by step diy project is about 16×18 gable shed plans. I have designed this 16×18 storage shed, so you can create a space for your tools, car accessories and other items any household has. This shed with a gable roof is also useful if you are a hobby woodworker or you have other outdoor hobbies that require a dedicated space. 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 16×18 shed floor and wall frames
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.
You can 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. Read the local codes before building the shed and choosing its location. Remove the vegetation layer and level the ground. Spread a 2-4″ layer of gravel, to help with drainage.
Attach 3/4″ plywood sheets to the floor frame of the shed. Cut the sheets to the dimensions shown 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.
Assemble the plain side wall frames from 2×4 lumber. Make sure the corners are square and align the edges flush for a neat result. Place the studs every 16″ on center for a neat result. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Measure the diagonals and make adjustments until they are perfectly equal.
Build the opposite side wall for the 16×18 gable shed. Cut the components from 2×4 lumber and the double headers from 2×6 lumber. Fit 1/2″ plywood between the double headers. Drill pilot holes and insert 2 1/2″ screws to lock the headers. You can adjust the size of the windows, so it suit your needs.
Fit the double header to the door, as well. You can adjust the size of the door to suit your needs. You can also play with the location of the window and door. Placing the studs every 16″ on center will help you create a structure that is really durable and very rigid.
Frame the front wall for the shed using 2×4 lumber for the studs and plates, while the double header requires 2×8 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Toe-nail the double header to the front wall. Make sure the corners are square and align the edges flush. You can easily adjust the size of the 8′ door opening to suit your needs.
Frame the back wall for the large storage shed, using the same techniques described above. You should use 3 1/2″ screws or 16d nails to lock the joints together tightly. Place the studs every 16″ on center and make sure the corners are square.
Fit the side, front and the back walls frames to the shed floor, as shown in the plans. Make sure the corners are square and then align the edges flush. Drill pilot holes through the bottom plates and insert 3 1/2″ screws to lock the adjacent walls together tightly. Use a spirit level to plumb the walls. Lock the adjacent wall frames together, by drilling pilot holes and insert 3 1/2″ screws.
You need to check out PART 2 of the shed, so you learn how to build the roof for the shelter. In addition, you need to make the double doors and attach the trims.
This is a simple project you should be able to build in a few weeks without much effort. Don’t forget to take a look over PART 2 to learn how to build the roof for the shed, as well as how to frame the doors.
