10×12 Saltbox Shed Plans

This step by step diy project is about diy 10×12 saltbox shed plans. I have designed this 10×12 garden shed with a saltbox roof so you can store lots of items and declog your backyard. This shed features double 6′ front doors and a side window. You can make modifications to the shed plans and install more windows. Moreover, I have designed shed with many sizes so check them out, as well. 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. 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 10×12 saltbox shed

Building the floor frame

The first step of the project is to build the floor for the 10×12 shed. Cut the joists from 2×6 or 2×8 lumber using a good saw. Align the beams, making sure the corners are square, drill pilot holes and insert 3 1/2″ screws to lock them together tightly. You can use joist hangers, as well. Read the local building codes so you make sure these plans comply with your legal regulations!

Fitting the skids

After assembling the floor frame, you need to attach the 4×4 skids. Use metal connectors to secure the skids to the joists, after aligning them or toenail them.

Floor sheets

Continue the project by attaching the 3/4″ plywood sheets to the floor frame. Leave no gaps between the floor sheets and secure them into place with 1 5/8″ screws, every 8″ along the joists.

Building the wall frames

Back-wall-frame

Assemble the back wall from 2×4 lumber. Cut the studs and the plates at the right dimensions. Drill pilot holes through the top plates and insert 3 1/2″ screws into the studs, using the information from the diagram. Alternatively, you can use a framing gun and nails. Make sure the corners are square for a professional result.

Wall Studs

As you can see in the plans, you need to fit 1/2″ plywood fillings to the double end studs.

Front-wall-frame

Continue the project by assembling the front wall. As you can notice in the diagram, you need to leave enough space for the door opening. You can easily adjust the size of the door to suit your nails. As you can see in the plans, you need to install the jack studs to reinforce the structure of the shed. Use 2×6 lumber for the double header.

Building the double header

The double header for the door is made from 2×6 lumber filled with 1/2″ plywood. Cut the plywood to size and glue it to the headers with construction glue. In addition, drive a few screws or nails to lock everything tightly.

Side-wall-with-window-frame

Build the side wall with window by following the instructions in the diagram. You should also notice the double plates that will add more rigidity to the walls and to the overall framing. You can adjust the size of the window opening to suit your needs. Notice the double plates and the studs.

Side-wall-frames

Frame the opposite side wall, as shown in the diagram. You can fit another window to the wall frame or even a side wall.

Assembling the shed frame

Fit the walls to the shed floor and lock them to the adjacent walls with 3 1/2″ screws. Make sure the corners are square and insert screws through the bottom plates into the floor, as well. Lock the adjacent wall frames together with screws to enhance the rigidity of the shed frame.

Fitting the siding sheets

Side wall siding panels

Build the exterior walls from 5/8″ T1-11 siding. As you can notice in the diagram, you need to make some cuts to the sheets so you cover the whole surface. Make a few notches to the sheets so you can fit it around the window opening. Use 8d galvanized nails to secure the sheets to the wall frames. Align everything with attention and insert the nails every 8″ along the studs.

Back wall siding panels

Cut the siding sheets to 72″. Fit the siding sheets to the back of the shed. Leave no gaps between the sheets and align them to the top plates.

Front wall panels

Attach the rest of the sheets to the front wall of the shed. Align the edges with attention and secure them to the wall studs with 8d nails or screws. Make sure you leave no gaps between the sheets for a professional result.
