This step by step diy project is about 16×24 lean to shed plans. I have designed this large shed with a lean to roof so you can have a large building for storing your tools, outdoor furniture and other items. Make sure you check the local codes and make adjustments to the plans, if required. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
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.

How to build a 16×24 Lean to Shed
The first step of the large shed project is to build the floor frame. Cut the components at the right dimensions and then lay them on a level surface. Use 2×8 lumber for the joists. Drill pilot holes through the rim joists and then insert 3 1/2″ screws into the perpendicular beams. Place the joists every 16″ on center, as in the diagram. Check if the corners are right angled and make adjustments, if necessary. Measure the diagonals and make sure they are perfectly equal.
Fit 4×4 skids under the floor frame. Align the edges and use rafter ties to secure the skids to the frame of the floor. Select the right location for the shed and then remove the vegetation layer. Compact a thick layer of gravel and make sure the surface is level. Alternatively, you can use posts and footings to secure the floor frame into place. Read the local building codes for the best choice.
Use 3/4″ plywood for the floor sheets. Take accurate measurements and use a circular saw to make the cuts. Fit the pieces of 3/4″ plywood to the floor frame. Align the edges flush and insert 1 5/8″ screws, every 8″ along the framing. Leave no gaps between the sheets and ideally, use tongue and groove sheets.
Build the side walls from 2×4 lumber. Cut the components from 2×4 lumber at the right dimensions. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Make sure the corners are square and place the studs every 16″ on center. Place double studs at both ends of the wall frames, as shown in the diagram.
Build the back wall for the shed using the same techniques described above and the information from the diagram. Place the studs every 16″ on center, as shown in the diagram.
Build the front wall for the lean to shed. Leave a 8′ opening for the double doors. Use 2×6 lumber for the headers. Sandwhich a piece of 1/2″ plywood between the headers, so you can enhance the rigidity of the structure.
The next step of the project is to build the top frame for the back wall. Cut the components at the right dimensions and then assemble the frame. 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.
Fit the wall frames to the floor of the shed. Align the edges with attention and plumb the walls with a spirit level. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Lock the adjacent walls together tightly using 3 1/2″ screws. Use temporary braces for the back and front walls, till you install the side walls.

This large shed is study and it is very efficient, in terms of costs. Moreover, you can save some space, as you can build it next to the property line or to an already existing building. I have lots of other shed projects on the site so I recommend you to browse through all alternatives before starting the building project. See all my shed projects HERE.
