The 7 DIY 12×20 Shed Plans

1. 12×20 shed plan from My Outdoor Plans

This shed is great for storing tools, but having only one door makes its utility for storing riding lawnmowers and ATVs pretty limited. On the other hand, it would serve well as an outdoor workshop or art studio or even as a pretty basic kids’ clubhouse. The plans from My Outdoor Plans include lists of everything you’ll need to build it.

With side access by a double door, this 12×20 shed from How to Specialist, on the other hand, is perfect for storing things you ride plus leaving space for shelves for tools and fuel cans. It’s also got a single-door entrance if you want to have a service bay on one side and a small workshop on the other. A list of tools and materials is available at the site.

4. 12×20 shed plans from YouTuber Nicholas Fargher

If learning by reading isn’t your cup of tea, YouTuber Nicholas Fargher created a series of videos showing you how to build your own 12×20 shed. We strongly suggest that if you go this route you follow his plans video-by-video, starting with a first watch-through so you have a clear idea of what you’ll need for each new segment. That’ll help you gather materials ahead of time and reduce frustration while building.
