Common Uses
Putting 1,600 square feet to work in a 40x40
Wide-open interiors and the lowest cost per square foot in the business mean a Keen's 40x40 works as hard as you do. These are the setups our specialists see most often.
Multi-Bay Garage & Shop
Several vehicles, a shop and storage under one roof. Wide truss spans keep the interior open and column-free.
Commercial & Fleet Storage

Horse Barn / Riding Setup
Room for a full row of stalls, tack and a wash or grooming area, or a covered work area for livestock.

Tall-wall options clear Class A motorhomes, large boats and lifted rigs, all under one open, drive-through cover.
Agricultural Equipment & Hay
Shelters large tractors, combines, sprayers and stacked hay, with 12 ft post spacing for easy equipment movement.
Workshop / Light Manufacturing
Clear-span floor for fabrication, welding or assembly work that needs room to maneuver materials and machinery.

Frequently Asked
40x40 pole barn questions, answered
How much does a 40x40 open pole barn cost?
Pricing on the 40x40 depends on your wall height (10 to 20 ft), and add-ons like windows, walk doors, roll-up doors and a 26-gauge upgrade, plus whether you choose a DIY kit or professional installation. Call 386-339-1676 for a firm, out-the-door quote in your county. Every installed barn qualifies for $0-down financing or rent-to-own with no credit check.
Why is the 40x40 built with 8x8 posts?
On 40x40 and larger pole barns we build with heavy-duty 8x8 pressure-treated posts as standard - the added load and uplift capacity is what these wider clear spans need. 6x6 posts are offered on our smaller buildings up to 24 ft wide.
What's included with a 40x40 open pole barn from Keen's?
Every 40x40 ships as a complete open post-frame building: 8x8 pressure-treated posts, engineered steel or metal-web trusses, a Galvalume metal roof at a 3/12 pitch, all framing and fasteners, and stamped, certified engineered plans for permitting. Installed orders in FL and GA are set up on your prepared site by our own crews; delivery is quoted by distance.
What can you fit in a 40x40 pole barn?
At 1,600 square feet, the 40x40 fits a multi-bay garage and shop, a full row of horse stalls, large RVs and boats, or commercial and agricultural equipment. Tell us how you'll use it and we'll help you spec the right height, posts and door layout.
What heights does the 40x40 pole barn come in?
Choose from 10, 12, 14, 16, 18 or 20 foot eave heights. Lower heights suit garages and workshops; 14 ft and up gives clearance for RVs, boats and tall equipment. Select your height in the options above.
Should I buy the DIY kit or have it installed?
A DIY kit ships pre-cut with all hardware and instructions to 13 Southeast states and usually saves 15 to 25 percent. Professional installation is available in Florida and Georgia, where our crews set the whole building. Delivery is quoted by distance to your site.
Do I need a permit for a 40x40 pole barn?
Most counties require a permit for a structure over 200 square feet, and a 40x40 is 1,600 square feet. Keen's provides stamped engineered plans sealed by a licensed Florida Professional Engineer with every pole barn, which is what your building department needs. Your specialist can help coordinate the submission.
How is the building engineered for wind and weather?
Keen's pole barns are engineered and certified to meet or exceed 150 MPH wind loads with posts set on 12-foot centers as standard (10-foot centers available as an upgrade). The Galvalume roof carries a 40-year paint warranty and resists Southeast humidity and salt air.
Can I add sides or close in a 40x40 pole barn?
Yes. The 40x40 is an open building by default, but you can add partial or full side panels, end walls, lean-tos, and walk or roll-up doors. Configure it in the 3D designer or call 386-339-1676 and we'll price the closed-in version for you.
Does Keen's deliver and install in my state?
Professional installation is available anywhere in Florida and Georgia, with delivery quoted by distance to your site. DIY kits ship to 13 Southeast states: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, Virginia and West Virginia. Call 386-339-1676 to confirm coverage.
