Mini Storage Buildings

Mini-storage buildings with maximum return.

Business owners and entrepreneurs throughout the Midwest choose FBi Buildings again and again for their mini-storage buildings. With low maintenance requirements and hassle-free construction, a post-frame building is the perfect solution for every growing business.


Not only do our post-frame buildings go up quickly and easily, they give you the design freedom to customize your floor plan to your unique needs. You can also put doors and windows just about anywhere without compromising structural integrity, and choose from a variety of attractive exterior finishes for greater curb appeal. And with our quality gutters and downspouts, the interior units will stay dry, giving your customers peace of mind that their valuables are safe.


No mini-storage building is too big or too mini. We’re with you every step of the way, from sales to design and construction, as well as help in zoning, permitting and financing.


Integrity, collaboration and experience—it’s all part of what separates us from the rest.
