8×12 Lean to Shed Plans – PDF Download

Ovidiu 0 GapDice RANDOM PLAN

This step by step diy project is about diy 8×12 lean to storage shed plans. This large backyard shed comes with a base of 8 ft x 12 ft and a lean to roof, with a 3:12 pitch. In addition, this shed has double doors to the front wall. Read the local codes and make adjustments to comply with your local requirements. 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 Lean to Shed 8×12

Floor frame

Floor frame

First of all, we need to build the floor for the shed from lumber. 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.

Measure the diagonals and make adjustments until they are perfectly equal.  Place the joists every 16″ on center.

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. Use 2 rafter ties and 1 1/2″ structural screws for each skid, one at a time.

Floor sheets

Floor sheets

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.

Next, we will start assembling the back wall frame for the shed. Therefore, cut all the components at the dimensions shown in the diagram, using 2×4 boards. Drill pilot holes through the top plates and insert 3 1/2″ screws into the studs. Align the edges flush and place the studs every 16″ on center. In addition, attach a double plate to the top of the wall frame.

Continue the project by assembling the front wall with the opening for the double doors. 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. Fit a piece of 1/2″ plywood between the double beams and then add glue to the joints. Align the edges flush and insert 2 1/2″ screws from both sides to assemble the header.

However, you should notice the double studs placed at both ends of the wall frame. Fit pieces of 1/2″ plywood between the double studs.

Next, assemble the side wall frames. Use the same techniques described above to assemble the wall frame.

 

Assembling the shed framing

Fitting the front and back wall frames

Fitting the front and back wall frames

Lift the front and back 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 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 2×4 braces.

Fit the side walls to the shed floor and lock them  to the adjacent walls with 3 1/2″ screws. Make sure the corners are square and insert 3 1/2″ screws through the bottom plates into the floor, as well.

Top wall frame

Top wall frame

Next, we need to frame the top wall that will create the lean to shape for this shed. This wall is designed in such a way that it will give this shed a 3:12 pitch. Drill pilot holes through the plates and insert 3 1/2″ screws into the studs. Place the studs every 16″ on center. Notice the double studs at both ends, with 1/2″ plywood pieces between them.

Fit the top wall frame to the front or back walls of the storage shed. Plumb the wall with a spirit level, drill pilot holes and insert 3 1/2″ screws.

Use 5/8″ T1-11 siding sheets for the exterior of the storage shed. Cut the panels and align them into place. Insert 6d nails, every 8″ along the framing, to secure the panels into place.

Attach the siding sheets to the front of the garden shed, as well. After securing the panels into place, make the cut outs around the double doors with a circular saw.

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.
