This step by step woodworking project is about free 16×20 shed plans. I have designed this 16×20 storage shed so you can shelter all your garden tools, sports equipment and so on. The large front doors makes the access really easy. Moreover, the side windows are large and let a lot of light inside, so you can work on your favorite hobbies See my other DIY projects HERE.
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 HERE.

How to build a 16×20 shed frame
Building the floor frame
The first step of the project is to build the floor for the shed. Cut the joists at the right dimensions from 2×6 or 2×8 lumber. Lay the joists on a level surface so you can assemble the floor frame in a professional manner. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular beams.
Fitting the skids
Select the location for the shed, taking into account your need and the local building codes. Level the surface thoroughly and then compact a thick layer of gravel. Set the 4×4 skids and then fit the floor frame. Toenail the frame to the skids, or you could use rafter ties so you lock them together tightly.
Fitting the floor sheets
Fit the 3/4″ plywood sheets to the floor frame and align the edges flush. Insert the 1 5/8″ screws along the joists, every 8″. Leave no gaps between the sheets for a professional result.
Side wall with window – Frame
Continue the project by assembling the side wall with windows. As you can see in the plans, this wall frame has two 36″x36″ window openings, so you can have a lot of light inside the shed. Cut the components from 2×4 lumber, after taking accurate measurements.
Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center, for a professional result. Use 2×6 lumber for the double headers. Fit 1/2″ plywood between the double beams and lock them together tightly with 2 1/2″ screws. Measure the diagonals and make sure the corners are square.
Side wall – Frame
Build the opposite side wall of the shed from 2×4 lumber. Cut the components from 2×4 lumber. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center and make sure the corners are square.
Front wall – Frame
Next, build the front wall frame for the 16×20 shed from 2×4 lumber. Use 2×6 lumber for the double header and 2×4 lumber for the rest of the components. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. You can easily adjust the size of the door opening, to suit your needs. Moreover, you could even frame a secondary door to the side of the storage shed.
Back wall – Frame
Build the back wall using the information from the diagram and the techniques described above.
Assembling the frame of the shed
Lay the wall frames to the floor of the shed. Align the edges flush and plumb them with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Moreover, you have to secure the adjacent walls together tightly, using 3 1/2″ screws. Make sure the corners are square.
Fitting the siding sheets
Side wall with window – Siding
Fit the T1-11 siding sheets to the side wall with windows. Make the necessary cuts so the sheets fit around the window openings. Align the edges flush, leave no gaps between the sheets and insert 6-8d nails, so you lock them into place tightly.
Front wall – Siding
Fit the T1-11 siding to the front of the shed. Make the cuts to the sheets, so you can fit them around the door opening. Use 6-8d nails, every 8″ along the framing, so you can lock them into place tightly.
Side wall – Siding
Fit the T1-11 siding sheets to the other side wall of the shed.
Back wall – Siding
Fit the T1-11 siding sheets to the back wall of the shed.
