The 12×20 Utility shed is the size most contractor-staging and equipment-plus-workshop customers settle on — 240 square feet, single-slope or A-frame roof, and double doors sized for a UTV, compact tractor, or a pair of motorcycles. At 20ft of length, this size parks equipment at the front and still leaves a long workbench wall with tool storage and a parts shelf. Common adds at this footprint: a second walk-through door on the long wall, two side windows for cross-ventilation, and dealer-installed shelving. This size is part of our Utility building line; if you need more length for stacked materials, related sizes include the 12×24 and the 12×28. Talk to a Cook dealer near you for delivery and pricing.

Frequently Asked Questions
How much does a 12×20 Utility cost?
A 12×20 Utility (240 sq ft) costs $7,565 cash, delivered fully assembled by your local Cook dealer. That price is for the standard building; options are quoted by your dealer.
What can fit in a 12×20 shed?
A 12×20 shed gives you 240 sq ft (12 ft by 20 ft) and 7'8" sidewalls — room for general storage, workshop, hobby space and home office.
Is a 12×20 shed delivered assembled?
Yes — a 12×20 shed is built at the factory and delivered fully assembled, usually in 7–10 working days. You will need about 14 ft of clear access width for the delivery truck and a reasonably level spot.
What base does a 12×20 shed need?
A 12×20 shed needs a level base at least 12 ft by 20 ft — a compacted gravel pad is the most common choice. Level ground protects the floor and keeps the doors square; your dealer reviews the site before delivery.
Do I need a permit for a 12×20 shed?
Whether a 12×20 shed needs a permit depends on your local building codes, not on Cook — check with your city or county before you buy. Cook provides building plans you can submit with your permit application.
How does the 12×20 Utility compare to the 12×24?
A 12×20 gives you 240 sq ft — 48 sq ft less than the 12×24 (288 sq ft) at the same 12 ft width, and about $434 more. Choose the 12×20 for a smaller footprint, or size up for extra length.
Can I customize a 12×20 Utility?
Yes — design a 12×20 in Cook's 3D configurator: choose siding and trim colors, place doors and windows, add a loft, then request a quote.
