10×20 Shed Plans

This step by step diy project is about 10×20 gable shed plans. This shed has a beautiful designs, so it is not only for storage but also for enhancing the look of your garden. The access is easy due to the double doors on one end, and a simple door on one side. The double doors will let plenty of light inside the shed. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Remember that you need to select the site for the shed with attention and that you have to comply with a few legal regulations. Premium Plans for this project available in the SHOP.

Now, let’s talk about the cost of building a 10×20 gable shed. You’re looking at around $2,000 to $3,000 for all the materials, depending on the quality of lumber, roofing, and siding you go with. If you decide to add extras like windows, a ramp, or insulation, you might want to budget an additional $500 to $800. This estimate should give you a solid idea to plan your budget and get started on your shed!

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.

How to build a 10×20 shed

Building-the-floor-frame-10×20-shed

First, build the floor frame for the 10×20 shed. Cut the joists from 2×6 lumber at the right dimensions. Align the edges flush, drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Place the joists every 16″ on center.

Select the right location for the large gable shed and then level it Compact a layer of gravel and then lay the 4×4 skids. Fit the floor frame to the skids and align the edges flush. Use rafter ties to secure the frame to the skids. Leave no gaps between the components for a professional result.

Fitting the floor sheets

Building the wall frames

Next, you have to assemble the side wall for the 10×20 shed. Cut the components from 2×4 lumber and 3 1/2″ screws. Place the studs every 24″, so you can get a professional result. Center the double top plate and lock it into place with 3 1/2″ screws. You can adjust the height of the side walls by cutting the studs shorter.

Side-wall-with-window-and-door-frame

Build the side wall with windows from 2×4 lumber. Use 2×6 lumber for the double headers. You can adjust the size of the windows, so you get enough light inside the shed for your needs. Fit 1/2″ plywood between the double 2×6 headers. Use 2 1/2″ screws and glue to sandwich the double headers in a professional manner.

Back-wall-frame

Build the back wall from 2×4 lumber, as well. Center the double top plate to the top of the wall frame and lock it into place with 2 1/2″ screws. Place the studs every 24″ on center for a professional result.

Front-wall-frame

Frame the front wall, making sure you leave enough space for the double doors. Cut the components from 2×4 lumber and the headers from 2×6 lumber. You can adjust the size of the double door to suit your needs.

Assembling the shed frame

Fit the wall frames to the top of the floor. Align the edges with attention and plumb the walls vertically. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor of the shed. Lock the adjacent walls together with 2 1/2 screws for a professional result.

Fitting the siding sheets

Side wall – Siding

Fit the T1-11 siding sheets to the sides of the 10×20 shed. Align the sheet to the wall frame and lock it into place with 6-8d nails. Leave no gaps between the sheets and lock to the framing, every 6-8d nails.

Side wall with window – Siding

Fit T1-11 siding sheets to the opposite side wall, for a professional result. Make sure you make cuts so the sheets can fit around the door opening and around the window openings. Use 6-8d nails and insert them every 8″ along the framing.

Front wall – siding

Fit the T1-11 siding sheets to the front of the shed. Make the necessarily cuts so the sheets can fit around the wall framing. Align the edges with attention and use 6-8d nails to lock the sheets into place tightly.

Back wall – Siding

Fit the T1-11 siding sheets to the back of the shed, as well. Leave no gaps between the sheets and align them for a professional result.
