These larger storage sheds are good for those who need to store items such as ATVs, motorcycles, and other vehicles that aren’t used on a daily basis. They’re also great for storing outdoor equipment like lawnmowers or tools that you use once or twice a year during certain seasons of the year.

Does a 12×20 Shed Need a Foundation?

It is recommended to have a 12×20 shed foundation for supporting your structure.

Blocks are the most affordable option and least labor-intensive. However, if you’re looking for something with a bit more structural integrity, we recommend building your shed on a 12×20 gravel foundation. This option is excellent for those who want to go above and beyond with their building plans, as the gravel pad drains better and provides superior support that will last over time. 

How Much Does the Foundation Cost for a 12×20 shed? 

Foundation costs depend primarily on the type of foundation and whether or not you need to hire professionals for installation. 

Hiring a contractor is the easiest way of ensuring that your 12×20 shed plans are brought to life as you imagined them, and this will also save time on research and legwork!

If you’re interested in constructing a gravel shed foundation yourself, this guide gives an excellent step-by-step overview of how to do that.

Here are some of the most popular 12×20 shed foundation options: 

Blocks – The cheapest option, but also the least durable.

Gravel (best) – Strikes a nice balance of affordability, durability, and ease-of-installation.

Concrete – The most durable and the most expensive option; concrete foundations are best for sheds that are built on-site and don’t include a built-in wood floor.
