Here’s the 12×18 Classic Sheds. They’re like our ranch-style sheds but with a steeper roof for more space. These sheds are versatile and can be used for different purposes, such as she sheds or home art studios.
Introducing the 12×18 High Barn Sheds: an excellent option for maximizing space within your shed. With a wall height of 75″, these sheds come with a built-in loft, and you have the choice to add another. If you’re seeking a shed that maximizes storage in its compact size, look no further.
The low barn shed has the design profile seen in the high barn sheds, yet it distinguishes itself with its lower sidewalls. This shed is an excellent option for efficiently storing a variety of gardening tools in a space-saving way. Its affordability adds to its appeal, making it a practical choice for those seeking budget-friendly storage solutions.
The quaker shed features a beautiful A-frame design with an offset roofline, providing extra overhang on the front of the building. This unique design profile instantly upgrades the style of your backyard.
The studio shed, also known as the modern shed, comes with a single-slope roof. It’s an ideal choice for those who prefer a modern style and is perfect for specialized uses like backyard offices, man caves, art studios, she sheds, and more!
In most areas, you will need a permit to install a 12×18 shed since a 12×18 shed exceeds 120 square feet. However, it’s crucial to verify any specific regulations or requirements with your local permit office before buying a shed of any size.
If you reside in North Dakota, please consult our shed permit guide for that state.
Establishing a foundation for 12×18 sheds typically means you’ll need around 3.5 cubic yards of gravel. We recommend extending the foundation’s dimensions by a foot on all sides compared to the shed’s size. Thus, you’ll need a pad measuring 14×20. We advise a depth of at least 4″. These calculations assume a level site. On sloped terrain, more gravel might be necessary. For comprehensive site preparation details, refer to our site prep page.
The overall footprint of 12×18 sheds is 216 square feet. However, bear in mind that the usable interior space will be slightly less due to wall thickness.
To calculate the usable floor space, subtract roughly 5″ from each side of the interior dimensions. This accounts for wall studs (3.5″) and exterior sheathing and siding (up to 1.5″).
Hence, for the calculation, multiply 11 feet 7 inches by 17 feet 7 inches, yielding an estimated interior space of approximately 187.5 square feet.
