The 12×28 Utility shed is the size that lands when a single building has to handle a workshop, equipment, and bulk storage in one footprint — 336 square feet, single-slope or A-frame roof, and double doors sized for a tractor, UTV, or trailered equipment. At 28ft of length, this size leaves room for an equipment bay at the front, a full workbench wall mid-building, and stacked feed or lumber storage at the back. Common adds at this footprint: a second walk-through door on the long wall, two or three side windows, and dealer-installed shelving. This size is part of our Utility building line; if you need maximum length for a two-bay workshop, related sizes include the 12×24 and the 12×32.

Frequently Asked Questions
How much does a 12×28 Utility cost?
A 12×28 Utility (336 sq ft) costs $9,935 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 12×28 shed?
A 12×28 shed gives you 336 sq ft (12 ft by 28 ft) and 7'8" sidewalls — room for general storage, workshop, hobby space and home office.
Is a 12×28 shed delivered assembled?
Yes — a 12×28 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 12×28 shed need?
A 12×28 shed needs a level base at least 12 ft by 28 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 12×28 shed?
Whether a 12×28 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 12×28 Utility compare to the 12×32?
A 12×28 gives you 336 sq ft — 48 sq ft less than the 12×32 (384 sq ft) at the same 12 ft width, and about $1,140 more. Choose the 12×28 for a smaller footprint, or size up for extra length.
Can I customize a 12×28 Utility?
Yes — design a 12×28 in Cook's 3D configurator: choose siding and trim colors, place doors and windows, add a loft, then request a quote.
