12x20 storage shed plans

If you are looking for a huge "shed" then the 12x20 shed plans may be your answer. The 12x20 shed has 240 square feet of floor space. These sheds are large enough that you can do many things that are impossible in smaller sheds. You can store a riding lawn mower and have a workshop. If you are building a home office you will have enough room for several people to work in their own space. Our large selection of 12x12 shed plans helps you to pick and build the perfect design so you can build your workshop, storage area or home office.

Shed Designs Using The 12x20 Shed Plan Size

iCreatables has several different shed styles including a regular gable shed design, a modern studio shed, a lean to shed, and a run in shed for livestock. Our 12x20 shed plans include those and the following popular shed designs:

12x20 Gable Shed Design: The gable shed is the most common style of shed. The lower slope roof keeps the overall building height lower than the colonial style. It comes with two doors, one large and one smaller. This allows you to easily move large items in and out of the shed through the large doors and the smaller door is used for daily entering of the shed.

12X20 Garden Shed Plans: Our colonial style sheds are the perfect solution for a large garden shed. With a steeper roof pitch, windows and a large door to make it easier to store larger items the 12x20 backyard colonial shed design will provied functionality and good looks for your yard or garden.

12x20 Shed Plans With A Porch: Our shed plan with a porch is a great way to build a storage shed and also have a fun place to hang out with covered porch. The 4x12 covered porch comes with handrail details. It has a 12x16 interior area that can be used as a workshop or storage space.

12x20 Lean To Shed Plans: Large lean to sheds are a simple way to get the storage or work space you need using simple construction techniques and no nonsense design. The simple one slope roof design makes the shed roof a bit easier to build. It also allows you to build the shed up against another structure and have the rain or snow to drain away. The roof overhang of the lean to shed is 6 inches on all sides. The roof overhang can be extended longer or shortened to fit your needs.

12x20 Shed Plans With Garage Door: A 12x20 shed with a garage door is the perfect way to increase accessibility to the shed. Having a large garage door allows you to easily drive 4 wheelers or riding lawn mowers into the shed. It also makes it easy to move large tools in and out of the shed to give you more space when it comes time to work in the back yard.

12x20 Horse Barn Plans: The 12x20 horse barn plans will create a large enough space for several horses or small animals. With 240 square feet you will have plenty of room for two horses. The recommended space for a horse is usually 10x12 feet which is 120 square feet. Horse stalls are typically 100 to 144 square feet.* The covered cantilever area gives protection in the front of the run in shed. *University of Nebraska-Lincoln Extension, Tips for New Horse Owners G2039.

12x20 Modern Shed Plans: The modern shed plan is perfect for a large office or as a guest bedoom. If you are looking to build a contemporary home office that you will be proud to work in and bring clients to or simply have a workout studio or guest bedroom then this is the plan for you. These plans allow you to build your own space for much less than purchasing a pre built design. It is designed with a low slope roof and the generous use of windows.

"Thanks a lot for the great plans.
The wife thanks you all because now she can park her truck in the garage for the winter!"

"Thanks for the designs!  They were especially useful since I didn't have any construction experience prior to this. Obviously, I made some modifications with the finishing, but I am quite happy with the size and structure of the shed." Matt

"Thank you Chris for the super service. The plans look great and I can't wait to get started." Frank

"I think these shed plans are great. I am very handy, but it is nice to have plans with measurements that are easy to follow. Most plans are to detailed, and confusing. I will prefab shed in garage, then in early spring put together. Thank you very much." Paul

"Hi. So I bought your plans and built the shed. Worked great, I would say 10/10...
Very easy to read the plans, very easy to make by following the steps in the "how to build a shed book" that comes with the plans. Overall, a very satisfied customer." Martin

"I just purchased your shed plans for the 6x8 Lean To Shed.  The quality of the plans is top-notch...  Thanks for the quick reply!  The quality to price ratio of your shed plan products is incredible.  Not to mention your awesome support.  I will most certainly be recommending icreatables shed plans to anyone I know who is interested in having a shed! Thanks again,"

"Thanks, Christopher. These plans and material lists are very complete, clear and easy to follow. Very nice work." Van


"I promised to send a photo of my completed shed.  My wife and I are very happy with the way it turned out.  The plans were exactly what I needed to get going...  It was a lot of work, but I learned a lot and it was fun.  Thanks for your help." Mike

"Your plans were very helpful. It was well worth the small price I paid for the extra help. Thanks." Robert

"Hi Guys, I built this shed as a well house and it is terrific, even though I have never been anything close to a carpenter. I have arthritis so I used screws everywhere but the roof, and I believe it will be stronger for it.

"Our shed looks great, thanks to your plans." Donald
"I had already paid out twelve dollars and change to another do it yourself website and was totally unhappy with the plans I got. Luckly I found your website and paid less for somthing ten times better. Thanks." Allen

"I have received (the plans), and they look wonderful!  Can't wait to get started (next week for sure!)  Thank you so much!" Phil

"BTW - so far after reviewing I'm thoroughly impressed with what you've done here in the attachments. For someone like me who isn't "handy" you've made it very easy for me to tackle." Fran

"Yes I did (receive the plans) ...freakin awesome! Thanks again!!" Jessi

"I finally finished my 8x12 shed! The plans worked out great. I deviated from the plans slightly on roof edge and the door.  I plan to put gutters and down spouts on it and we wanted a little more of a country barn door look. I really appreciated the templates for cutting the notches for the rafters.  Detailing which nails I needed for each phase of the build was also very helpful. Thanks again," Dale

"I really like the instructions, they are much more than I expected." Randy

"Thank you for your input.  I just purchased the 4x4GN-generator-shed-plans.  Wow. The plans look fantastic. And the parts list is very nice!  I plan to modify it with 2 or 3 side doors for extra ventilation as needed. Thanks again for your time." Vern

"I like the idea of constructing the unit from scratch, what I call stick building it piece by piece - we've seen the lightweight think plastic walled units from (a home store), ok I guess but the heavier wooden unit with permanent roofing will last longer and give better service.   It was a good plan and easy to build from, I don't think  the contractor had any difficulties with it." Gary

"I purchased your plans for a 12 x 12 shed w/garage door. Your plans were great and I'm very pleased with the results.
I also used your free "how to build a ramp" plans which were very helpful." Regards, Donald

"Hello!  Our Shed project went swimmingly well this weekend! The only thing you’ll notice we did different was to order the doors from a lumberyard rather than building them…. Which worked out pretty well.  Thanks for your help!" Maureen

"Got them. I'm very pleased with plans."
Thanks. Timothy

"Great shed plans, the material list helped a lot as well!"
Sincerely, Jeff

"Thanks very much!  Great service and good prices.  I'll be buying more plans from you in the future!" Cheers, Darren

"Attached are photos of woodshed I built from your plans....the plans made it very easy....Thanks" Mike

"It to me a year of intermittent sweat swearing and blood, but I finished it, and I'm proud of it. Thanks for the awesome shed plans!" Jessica

"I recently helped a family member build an 8x12 shed using plans he bought from your site and found the plans and materials list to be very helpful.  I'm about to start a project building my own storage building, a 12x20, and thought I'd buy plans from you as well since his went so smoothly." David

"I was sceptical about buying shed plans online but your extremely customer service and willingness to provide extra help to a "newbie" have won me over. Thank you.
Be well,"

Thanks again for your helpful information! Pictures to come!"
