10×20 Shed Plans

by Ovidiu

 

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.

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.

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.

I am interested in building this shed as a place to store boats in the winter in NH. The roof framing seems really close, and I am wondering if I can get away with something a little less close. .

Ideally I could space the ceiling joists further apart in order to be able to stick paddles and stand up paddle boards up there. Do you have any thoughts on how much I would have to go up in stock in order to have the joists spaced further apart? Do you have or know of plans for this size that has ceiling joists that are heavier stock and further spaced apart?

You can use engineered trusses and space them up to 4′ oc. Something like in this plans: https://myoutdoorplans.com/shed/16×24-pole-barn-plans/

Please take a look over Part 2 of the project, for details on the roof structure.

I like the plans for the 10’x20′ shed. I want to put a loft in on both ends. How would I modify the plans to allow for a loft and still maintain roof integrity?

You need a ridge beam. 2x8s for the bottom chords.

I bought the PDF for the 10×20 shed, after looking over this version online. I noticed several differences in the online and PDF versions, and wondered if there were practical reasons.
1. The online version uses the full 96″ lengths for the siding, while the PDF trims several inches from the lengths. Was there a reason for that? Seems like less cutting required for full sheets.
2. The roof pitch is slightly different. Trusses cut at 30 degree for online, and 26.5 for the PDF. Is one better?
Thanks!

The Premium Plans are re-engineered versions of the free plans. The 26.5 is a standard 6:12 roof pitch. The difference regarding the siding sheets is determined by different wall heights.

Are there more professional plans available for this shed that I can submit to the county so I can get a permit, Can the pitch be made a 5/12?? I have already bought these plans last year and have built the shed. Looks good but I did not know I needed a permit.
