This step by step diy project is about diy 12×16 lean to shed plans. If you are looking for a large lean to shed project, I recommend you to check out these plans. This shed is both roomy and has a nice lean to appearance. Moreover, I have designed shed with many sizes so check them out, as well. 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. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build a 12×16 shed
Build the floor for the shed from lumber. Alternatively, you can pour a concrete floor if you want a permanent construction. Cut the joists from 2×6 lumber using a good saw. Align the beams, making sure the corners are square, drill pilot holes and insert 3 1/2″ screws to lock them together tightly.
After assembling the floor frame, you need to attach the 4×4 skids. Use metal connectors to secure the skids to the joists, after aligning them or toenail them.
Continue the project by attaching the 3/4″ plywood sheets to the floor frame. Leave no gaps between the floor sheets and secure them into place with 1 5/8″ screws, every 12″ along the joists.
Assemble the side walls from 2×4 lumber. cut the studs and the plates at the right dimensions. Drill pilot holes through the top plates and insert 2 1/2″ screws into the studs, using the information from the diagram. Alternatively, you can use a framing gun and nails. Make sure the corners are square for a professional result.
Fit 1/2″ plywood fillings to the end studs, so you reinforce the walls.
Continue the project by assembling the front wall. As you can notice in the diagram, you need to leave enough space for the door opening. You can easily adjust the size of the door to suit your nails. Use 2×6 lumber for the double header.
The double header for the door is made from 2×6 lumber filled with 1/2″ plywood. Cut the plywood to size and glue it to the headers with construction glue. In addition, drive a few screws or nails to lock everything tightly.
Build the back wall using the same techniques described above. You should also notice the double plates that will add more rigidity to the walls and to the overall framing.
Lift the side walls and lay them to the floor of the shed. Align the edges with attention and use a spirit level to plumb the walls. Drill pilot holes through the bottom plates and insert 2 1/2″-3 1/2″ screws into the floor frame, every 8″. As you can notice in the plans, you need to secure the walls into place temporarily with braces.
Fit the front and back walls to the shed floor and lock them to the adjacent walls with 2 1/2″ screws. Make sure the corners are square and insert screws through the bottom plates into the floor, as well.
Make sure you check PART 2 of the project, so you learn how to build the roof for this large lean to shed project. In addition, you could check the rest of the shed plans I have on this site for more building ideas.
If you want to see newer plans for a 12×16 lean to shed, that also features a side door and a window, with much stronger frame (suitable for snow), take a look over these plans.
Last but not least, you should take care of the finishing touches. Therefore, fill the holes with wood putty and let the compound to dry out for several hours. Smooth the surface with medium-grit sandpaper along the wood grain.
Top Tip: Take a look over PART 2 of the project, so you learn how to build the roof and the front double doors for this shed project.
