This step by step diy woodworking project is about 12×16 barn shed plans. The project features instructions for building a large shed with a gambrel roof, that has a significant storage space. If you want to build a basic storage barn with loft, take a look over these plans. Check out PART 2 of the article to see how to frame the roof of the shed. See the rest of plans for more outdoor projects. 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. Read the local building codes before starting the project, as you might need a building permit. In addition, level the area and remove the vegetation layer. See all my Premium Plans HERE.

Building a 12×16 gambrel shed
The first step of the project is to build the floor frame of the shed. Cut the components from 2×6 lumber and drill pilot holes through the rim joists. Align the edges with attention and check if the corners are square before inserting the 3″ screws.
Attach 4×4 skids under the floor frame to protect it from moisture.
Attach the 3/4″ plywood sheets to the floor frame. Align the edges with attention and leave no gaps between the components. Use 1 5/8″ screws to lock the plywood sheets to the joists, every 8″.
Build the side walls from 2×4 lumber. Cut the components from 2×4 lumber, after taking accurate measurements. Drill pilot holes through the plates and insert 2 1/2″ screws into the studs. Place the studs every 24″ on center and make sure the corners are square.
Fit the side walls to the floor of the shed. Use a spirit level to plumb the walls and lock them into place with 2×4 braces. Drill pilot holes through the bottom plates and insert 3″ screws into the rim joists.
Build the front wall for the barn shed using the instructions described in the diagram. Cut the components from 2×4 lumber. Drill pilot holes through the plates and insert 2 1/2″ screws into the studs. Make sure the corners are square and align the edges. In addition, you can adjust the width of the door to suit your needs.
Build the header from 2×6 beams and 1/2″ plywood. Cut the beams at 63″ (ignore the 60″ in the diagram, which is wrong). Fit the plywood between the beams. Drill pilot holes through the beams and insert 2 1/2″ screws, on both sides of the header.
Build the back wall from 2×4 lumber, using the information from the plans and following the techniques described above.
Fit the front and the back walls to the floor of the barn shed. Align the edges with attention and make sure the corners are square. Drill pilot holes and lock the adjacent walls together with 2 1/2″ screws. In addition, connect the double plates together with 2 1/2″ screws.
Attach T1-11 siding to the sides wall, as shown in the diagram. Align the top of the sheets and lock them into place with 1 5/8″ nails, every 8″ along the studs. Leave no gaps between the sheets for a professional result.
Attach siding sheets to the back of the shed, as well.
Make a few cuts to the sheets, so that they can fit around the door opening.
Make sure you check PART 2 of the project to lean how to frame the roof for the gambrel shed.
Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-200 grit sandpaper and remove the residues with a damp cloth. Premium Plans for this project available in the Shop.
