14×20 Gambrel Shed – Free DIY Plans

by Ovidiu

 

This step by step diy project is about 14×20 gambrel shed plans. I have designed this large barn shed so you can store all your tools, bikes, furniture and other items. This shed has double front doors, a side door and a side window. You can easily make modifications to my plans, so the shed suits your needs and tastes. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the location for the shed with attention and that you have to comply with a the local building regulations.

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.

Step 1: How to build a 14×20 barn shed floor

Floor frame

Floor frame

The first step of the project is to build the floor frame for the storage shed. Therefore, you have to cut all the joists from 2×6 lumber. Lay all the joists on a level surface and drill pilot holes through the rim beams. Insert 3 1/2″ screws through the rim joists into the perpendicular components. Make sure the corners are square and align the edges flush. Place the joists every 16″ on center, for a professional result.

Make sure you read the local building codes, so you can get the job done in a professional manner. In addition, select the location for the storage shed with attention, so you can comply with the codes and to use your yard efficiently.

Fitting the skids

Fitting the skids

Next, select the location for the large barn shed, remove the vegetation layer and then compact a thick layer of gravel. Use a spirit level to make sure the surface is perfectly horizontal. Lay the 4×4 skids to the  ground and then fit the floor frame.

Also, align the edges flush and use rafter ties to lock the skids to the floor frame tightly. You can also use anchors so you can lock the shed to the ground, in the case you live in an area with strong winds.

Floor sheets

Floor sheets

Additionally, cut the floor sheets to the right dimensions. Attach the 3/4″ tongue and groove plywood sheets to the floor frame, using the pattern show in the plans. Align the edges flush and leave no gaps between the sheets. Insert 1 5/8″ screws every 8″ along the joists, for a professional result.

 

Step 2: Building the shed wall frames

Front-wall-frame

Continue the project by assembling the front wall for the 14×20 gambrel shed. Cut the components at the right dimensions and then drill pilot holes through the plates. Insert 3 1/2″ screws through the plates into the studs.

Furthermore, use 2×6 lumber for the door double header. Fit a piece of 1/2″ plywood between the 2×6 headers. Add glue to the joints, drill pilot holes and insert 2 1/2″ screws to lock everything together tightly. You can adjust the size of the door opening to suit your needs.

Back-wall-frame

Back-wall-frame

Build the back wall for the storage shed in the same manner described above. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center for a professional result. Make sure the corners are square and align the edges with attention.

Side-wall-frame

Side-wall-frame

Next, frame the plain side wall for the 14×20 storage barn shed. As you can easily notice in the diagram, you need to use 2×4 lumber for the plates and studs. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place 1/2″ plywood blockings between the double studs that are placed at both ends of the wall frames.

Side-wall-with-door-frame

Next, you need to assemble the opposite side wall for the shed. Cut all the components from 2×4 lumber at the dimensions shown in the diagram. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center and make sure the corners are square. Use double studs and 1/2″ plywood for both ends of the wall frame.

As you can easily see in the diagram, you need to frame a door to the side wall. In addition, frame a small window, so you can let a lot of light inside the shed.

 

Step 3: Assembling the shed wall frames

Continue the project by fitting the wall frames to the floor of the shed. Align the edges flush and then plumb them with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Join the adjacent walls together tightly using 2 1/2″ screws. Make sure the corners are square for a professional result.

 

Step 4: Attaching the shed siding sheets

Cut the T1-11 siding sheets to the right dimensions and then secure them to the side wall frame. Make the cuts so you can fit the panels around the door and window openings. Use 6-8d nails to lock the sheets into place, every 8″ along the framing for a professional result.

Next, fit the T1-11 siding panels to the other side of the shed. Align the edges with attention and leave no gaps between the panels, for a professional result. Use 6d nails to secure the panels, every 8″ along the framing.

Back wall siding panels

Back wall siding panels

Attach the T1-11 siding panels to the back of the shed. As you can easily notice in the plans, you need to inset the sheets 1 1/2″ from the top plate. Use 6-8d nails to lock the sheets into place. Insert the nails every 8″ along the framing for a professional result.

Cut the sheets for the front of the shed. Align the sheets and then lock them into place with 6-8d nails, as shown in the diagram. Fit the sheets 1 1/2″ below the top plate.
