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

Building-the-floor-frame

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.

Attaching the skids

Attach 4×4 skids under the floor frame to protect it from moisture.

Attaching the plywood floor

Attaching the plywood floor

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″.

Building wall frames

Building-the-side-wall-frame

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.

Attaching the side walls

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.

Building-the-front-wall-frame

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.

Header

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.
