This step by step diy project is about diy 12×16 shed plans. If you are looking for a large storage shed that is both easy to build and that has a really nice appearance, then you should take a look over my plans. This garden project has more parts so take a look over the rest of the sections to learn how to build the roof and the door. 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. Premium Plans for this project available in the Shop.
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 12×16 shed
The first step of the project is to build the floor for the 12×16 shed. Cut the joists from 2×6 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.
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.
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 1/4″ screws, every 12″ along the joists.
Assemble the side walls from 2×4 lumber. cut the studs and the plates at the right dimensions. Drill pilot holes through the top plates and insert 2 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.
As you can see in the plans, you need to fit 1/2″ plywood fillings to the end studs.
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.
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.
Build the back wall using the same techniques described above. You should also notice the double plates that will add more rigidity to the walls and to the overall framing.
Lift the side walls and lay them to the floor of the shed. Align the edges with attention and use a spirit level to plumb the walls. Drill pilot holes through the bottom plates and insert 2 1/2″-3 1/2″ screws into the floor frame, every 8″. As you can notice in the plans, you need to secure the walls into place temporarily with braces.
Fit the front and back walls to the shed floor and lock them to the adjacent walls with 2 1/2″ screws. Make sure the corners are square and insert screws through the bottom plates into the floor, as well.
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. 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.
Make the cuts to the sheet that goes around the door opening. Align everything so the edges are flush and secure them into place with 8d nails.
Attach the rest of the sheets to the back 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.
Make sure you check out the rest of the project, so you learn how to frame the roof and how to attach the door and the trims to the shed. In addition, I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project.
