Uses For 16x20 Shed Plans

16x20 is a large shed design. There are many uses for this size of shed that include everything from storage to back yard living space, detached garage or even a home office. All of our 16x20 designs, except for the lean to, are intended to use roof trusses designed and manufactured by a local truss company so that they will meet the needs of your local roof loading conditions.

Because of the large size the 16x20 sheds typically require a building permit. As a precaution before building this shed or any other shed you should be sure to verify with your local building department the codes in your area during the planning stages of your project.

Our 16x20 shed plans include the following popular shed designs:

Our 16x20 storage shed plans have a great variety of shed styles to fit many diffferent design needs including the following:

16x20 Traditional Shed Design: The traditional style shed has design features that are found in many regions across the country. The gable shed comes standard with a 10/12 pitch roof but that can be changed when the roof trusses are ordered to be less of a pitch or more of a pitch. The roof overhang is 1'-0".

16x20 Lean To Shed Plans: If you need a large lean to shed the 16x20 lean to design is a great solution. Utilizing the simplest shed design the lean to has a single plane roof which allows it to be built close to another structure, like a fence or building, and still keep all the rain and snow moving away. Our lean to shed design has optional framing plans for the doors on any of the shed walls from the tall wall, end walls and short wall.

16x20 Garage Door Shed Plans: Our garage door sheds come with construction details showing how to trim the garage door opening. The large door allows you to store large equipment and even a car, as long as it will fit the length of the shed. This shed can be built on wood skids or concrete foundation.

16x20 Garden Shed Plans: The Nantucket style shed is defined by its steep 12/12 roof pitch and side door being centered between two windows. Details are included showing how to install the rake and eve fascia to match the design of the Nantucket style.

Roof Framing For Large Sheds:

Because of the large 16 foot span of the 16x20 shed roof trusses or rafters our plans recommend the use of pre-engineered roof trusses. This is common for structures of this size because the increased loads for such a large roof area are much greater than smaller sheds. By having the trusses engineered and built by a local truss plant you will be sure to have a roof structure that is strong enough to handle the roof loads found in your area.

Installing engineered and pre-built trusses will save you many hours of work building them on site.

The lean to shed is designed to use Engineered lumber for the roof rafters. These "I" joists come with engineering that describes the load capacities of the joists at different lengths for different spans. Verify locally that the loading conditions meet or exceed the design shown on the plans. Your building department or lumber sales person can help you with this.

16x20 Shed Foundation Styles

The 16x20 sheds have two different foundation plans that come standard with each plan. These are Concrete slab and wood rail with a framed floor.

  • Concrete Slab: The concrete slab floor and footing is a permenant floor system. It consists of a 4" thick concrete slab and a 12 inch thick monolithic footing around the perimeter. Check locally to verify the footing depth required for storage buildings and to make sure that the shed footings are deep enough to meet the frost depth if this is required. Shed floors that are made from concrete are typically just a bit more costly than a wood framed floor and wood rail foundation.
  • Wood Rail Foundation: This is the most commonly used foundation for smaller sheds and is often used on larger sheds. It consists of wood rails set on a bed of crushed gravel. The wood floor system is framed on top of the wood rails.

Planning To Build A 16x20 Shed

Planning to build your shed is an extremely important part of building your shed. Before you actually start cutting wood and nailing it together you will need to consider the following questions:

  • How large of a shed do I want and need to build?
  • What is the best style of shed for my needs?
  • What will the 16x20 shed cost to build?
  • Where on my property will I build the shed?
  • How will having the shed on my property affect the traffic moving to it and around it?
  • What does my city or county require for building permits when building a shed?

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!"
