12×16 Gambrel Shed Plans

This step by step woodworking project is about free 12×16 shed plans. If you want to create a lot of storage space in your backyard, I recommend you to check out these plans for a compact barn shed with a loft. In this manner, you can use the space efficiently and add real value to your backyard and life. See my other DIY projects HERE. PDF downloadable plans, for this project, with premium features in the Store.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. See all my Premium Plans in the Shop.

How to build a 12×16 barn shed

Building the floor frame

The first step of the project is to build the floor frame for the barn shed. As you can easily notice in the diagram, you need to cut the joists at the right dimensions. Align the edges flush, making sure you place the joists every 24″ on center. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components.

Fitting the skids

Lay the 4×4 skids on the selected location for the shed. Align the edges with attention, using the information from the diagram. Fit the floor frame to the skids, making sure you align the edges properly. Use rafter ties to secure the skids to the floor frame, as well as screws.

Fitting the floor

Lay the 3/4″ plywood sheets to the floor frame. Align the edges flush, leave no gaps between the sheets, drill pilot holes and insert 1 5/8″ screws into the joists. Smooth the edges flush.

Building the wall frames

Back wall – Frame

Assemble the wall frames for the barn shed from 2×4 lumber. First, you need to cut the components at the right dimensions, using a good saw. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center. Align the edges flush, making sure the corners are square.

Side wall – Frame

Frame the side walls, in the same manner described above. As you can easily notice in the plans, you need to double the studs that are placed at both ends of the side walls. Place 1/2″ plywood blocking between these double studs.

Building the double header

Continue the project by framing the double header for the barn shed. Cut the headers from 2×6 lumber and place 1/2″ plywood between them. Add glue, drill pilot holes and insert 1 1/2″ screws to lock them together tightly.

Front wall – Frame

Having the double header, you need to frame the front wall for the barn shed. Use 2×4 lumber for the plates and the studs. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs,.

Assembling the frame of the shed

Fit the wall frames to the floor of the shed. Align the edges flush, drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. In addition, you need to lock the adjacent walls together tightly by using 3 1/2″ screws. Use a spirit level to plumb the walls and a carpentry square to make sure the corners are right angled.

Attaching the siding sheets

Side walls – Siding

Attach the T1-11 siding sheets to the sides of the barn shed. Align the edges flush and insert 6-8d nails, every 8″ along the framing.

Front wall – siding

Cut the sheets for the front wall of the shed.  As you can see in the plans, you need to inset the sheets 1 1/2″ from the top edge. Use 6-8d nails to lock the sheets into place tightly.

Back wall – Siding

Fit the sheets to the back of the barn shed, as well. Use the same techniques described above, to secure them into place tightly.
