8x20 Run In Shed Plans - Free PDF Download

This step by step diy project is about free 8×20 run in shed plans. I have designed this compact run in shed so you can build it quickly and save money. I have optimized everything so you can make use of the materials efficiently. This shed features 12″ back and sides overhangs and 24″ front overhang. Read the local codes before starting the project, so you comply with the legal 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. See all my Premium Plans HERE.

Building a 8×20 run in shed

Laying-out-the-posts-for-the-8×20-run-in-shed

The first step of the project is to layout the posts for the 8×20 run in shed and to set them into place. Dig 3′ deep 12″ in diameter holes for the concrete footings. Set the concrete forms and then fill them with concrete. Set the post anchors, making sure they are aligned properly. After a few days, set the 4×4 posts into place with lag screws and temporarily braces.

Fitting the bottom skids – 8×20 run in shed

Use 4×4 skids between the posts. Drill pocket holes at both ends and insert 2 1/2″ screws to secure them to the posts (on both sides). Make sure the corners are square and align the edges flush.

Building the headers – 8×20 shed

Build the headers for the run in shed from 2×12 beams and 1/2″ plywood. Use construction glue for the joints and insert 2 1/2″ screws on both sides of the headers. Align the edges flush and clamp them together tightly.

Fitting the headers

Fit the beams to the top of the posts. Use connectors to secure the beams to the posts. Make sure the posts are plumb and check if the corners are square. Align everything with attention. Use a spirit level to check if the beams are perfectly horizontal and cut the top of the posts, if necessary.

Next, you have to build the side walls from 2x4s. Cut the plates and the studs as 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.

Assemble the sections for the back wall using the info from the diagram. You need 2 wall frames.

Assembling the shed frame – 8×20 run in

Fit the wall frames between the posts and align the edges flush. Drill pilot holes and insert 3 1/2″ screws through the wall frames into the skids, posts and headers.

Fitting the siding sheets – front wall

Fit the T1-11 siding sheets to the front of the shed, as shown in the plans. Cut the sheets at the right dimensions and then attach them to the framing with 6d nails, every 8″ along the studs and plates.

Fitting the back siding sheets - 8x20 run in shed

Fitting the back siding sheets – 8×20 run in shed

Fit the 5/8″ siding sheets to the back of the shed. Align the edges with attention and leave no gaps between them for a professional result. Use 6d nails, every 8″ along the framing, to secure the sheets into place tightly.
