This step by step diy project is about 10×20 outdoor storage shed plans. I have designed this 10×20 gable shed so you can store a lot of items. This garden shed features double front doors and a 36″x80″ side door with two windows. 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.

How to build a 10×20 storage shed
First of all, you need to frame the floor for the shed. Cut the joists for the floor from 2×6 or 2×8 lumber at the right dimensions. Lay the joists on a level floor and then align the edges with attention. Drill pilot holes through the rim joists and insert 3 1/2″ screws into the perpendicular components. Make sure the corners are square and place the joists every 16″ on center.
Select the location for the outdoor storage shed and level it with attention. Compact a thick layer of gravel and then lay the 4×4 skids into place. Fit the floor frame and then use metal ties to lock them together tightly.
Cut the 3/4″ plywood sheets at the tight dimensions and then lay them to the floor frame. Align the edges and insert 1 5/8″ screws, every 8″ along the joists. Leave no gaps between the sheets for a professional manner.
Continue the project by framing the side wall with windows. As you can see in the plans, you should also frame a 36″x80″ door, so make sure you leave enough space for fitting one. It would be best to have the vinyl door before framing the wall, so you can make adjustments to my plans, if necessary.
Cut all the studs and plates from 2×4 lumber. Cut the headers from 2×6 lumber and 1/2″ plywood. Fit 1/2″ plywood between the double headers and lock them together 2 1/2″ screws. Toenail the headers to the studs so you can lock them into place tightly.
Build the opposite side wall for the 10×20 shed from 2×4 lumber. Cut all the components and lay them to the floor of the shed. Drill pilot holes though the plates and insert 3 1/2″ screws into the studs. Place the studs every 24″ on center, for a professional result. Fit the double plates into place with 2 1/2″ screws.
Frame the back wall from 2×4 lumber. Use the same techniques described above to frame the back wall.
Building the front wall is a straight forward process, but you need to frame a large opening for the double doors. Fit the 2×6 header to the top of the door. You can adjust the size of the opening to suit your needs.
Fit the wall frames to the floor of the shed. Align the edges with attention and use a spirit level to plumb the vertically. Drill pilot holes through the bottom plates and insert 3 1/2″ screws into the floor. Moreover, you need to lock the adjacent walls together tightly. Drill pilot holes and insert the 3 1/2″ screws for a professional result.
Fit the T1-11 siding sheets to the front wall. Make cuts to the sheets so you can fit them around the opening. Align the edges flush and insert 6-8d nails, every 8″ along the framing.
Fit the sheets to the back wall, using the same techniques described above.
Fit the T1-11 siding sheets to the side wall of the shed.
Fit the T1-11 siding sheets to the opposite side wall. Make the cuts so you can fit the panels around the door opening and around the window openings.
You need to take a look over PART 2 of the project, where I show you how to build the roof for the shed. Moreover, take a look over PART 3 of the project, where I show you how to build the doors for the shed and how to fit the decorative trims.
This storage shed is ideal for any property, if you have a lot of items to shelter. The double front doors are great if you want to have an easy access to the shed. The side wall and windows make it an option for using it as garden shed. You can store outdoor furniture, bikes and even a lawn mower.

Would you happen to have the plans the same as the 10×20 Gable roof shed in a 7×14 size with the 36×80 side door and no end doors? I’m looking to build in a confined space and would rather follow something exact than trying to guess how to make it smaller.
This site is awesome and thanks so much for making it possible for us wanna be carpenters!
Unfortunately, I don’t have plans with those specifications.
I’m looking at building a 10×18 shed similar to this. would it be hard to adjust the plans?
No, you can do that. Just a matter of making the floor, side wall frames and roof smaller. Everything else is the same.
Are there PDF plans available for this10’ x 20’ gable shed?
Yes, there is an improved version of this in the Shop: https://myoutdoorplans.com/shop/
The 10×20 gable roof plan has the door in the front center and in the premium plans the door is to the far right. Is there a premium plan with the door centered?
