12×12 Saltbox Shed Plans

This step by step diy project is about 12×12 saltbox shed plans. I have designed this square shed with a saltbox roof, so you can store garden tools and other items without much effort. This shed features a 4′ wide front doors 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.

Building a 12×12 saltbox storage shed

Building the floor frame

The first step of the project is to build the floor frame for the shed. You can use 2×6 lumber or even 2×8 lumber if you are going to store heavy items. Cut the components at the right dimensions and then drill pilot holes through the rim joists. Insert 3 1/2″ screws to lock the joists together. Align the edges flush and make sure the corners are square.

Fitting the skids

The next step if to attach 4×4 skids under the floor frame. The wood skids will lift the floor frame from the ground for a few inches and thus, protect it from the elements. Attach the skids to the floor frame using metal connectors or by inserting screws through the frame into the skids.

Fitting the floor sheets

Lay the 3/4″ plywood sheets to the floor frame. Cut the sheets at the right dimensions, as shown in the plans. Align the edges flush, leave no gaps between the components and then insert 1 5/8″ screws to lock them into place tightly.

Side-wall-with-window-frame

Continue the project by assembling the side wall frame with window. Cut the plates and the studs from 2×4 lumber. Take accurate measurements and use a saw to make the cuts accurately. Drill pilot holes through the plates and insert 3 1/2″ screws or 16d nails into the studs. Place the studs every 16″. Make sure the edges are flush and check if the corners are square for a neat result.

Use 2×6 lumber for the double headers. Cut the headers at the right dimensions and sandwich a piece of 1/2″ plywood between them. Add glue to the joints and align the edges with attention. You can adjust the size of the window opening to suit your needs.

Side-wall-frame

Use 2×4 lumber for the opposite side wall. Place the studs every 16″ on center, using the information in the diagram.

Front-wall-frame

Assemble the front wall for the saltbox storage shed using the above instructions. Make sure you leave enough space for the door opening. You can make adjustments to suit your needs. Check if the corners are square and align the edges with attention. Use 2×6 and 1/2″ plywood for the double door header. You can adjust the size of the door opening to suit your needs.

Back-wall-frame—12×12-saltbox-shed

Build the back wall for the shed. Cut the components at the right dimensions and then assemble the wall frame together using 3 1/2″ screws or 16d nails. Measure the diagonals and make sure they are equal.

Assembling the shed frame

Fit the walls to the floor frame of the storage shed and align the edges flush. Use a spirit level to plumb the walls and drill pilot holes through the bottom plates. Insert 3 1/2″ screws into the floor of the shed for a neat result. In addition, lock the adjacent walls together using 2 1/2″ screws.

Top front wall

Use 2×4 lumber for the top front walls. Cut the components at the dimensions shown in the diagram. Drill pilot holes and insert 3 1/2″ screws through the plates into the studs. Place the studs every 16″ on center and make sure the corners are square.

Fitting the front top wall

Fit the frame to the top of the back wall. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly. Use a spirit level to plumb the wall frame.

Side wall panels

Fit the T-11 siding sheets to the side of the shed. For the side wall with window use a saw to make the opening.

Front wall siding sheets

Fit the T1-11 siding sheets to the front of the shed. Cut the sheets at the right dimensions and then secure them into place with 66-8d nails.

Back wall siding panels

Fit the siding sheets to the back of the shed.

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain so you enhance the look of the shed and you protect the components from decay. Don’t forget to take a look over PART 2 to learn how to build the roof for the shed, as well PART 3 to learn how to frame the front door.
