Whether you’re a farmer in Des Moines, a business owner near Cedar Rapids, or managing a property in Peoria or Springfield, our team delivers buildings that combine strength, functionality, and long-term durability.
Our machine sheds and shop buildings are engineered to withstand the Midwest’s toughest weather conditions, providing reliable protection for farm equipment, vehicles, and machinery. Every Greiner post-frame building is constructed with premium materials and backed by decades of expertise, ensuring a long-lasting investment.
Greiner Buildings specializes in machine shed and shop combination buildings that give you both storage and workspace under one roof. Whether you need a large shed for tractors and combines in Davenport or Rockford, or a fully insulated shop for year-round maintenance in Iowa City or Bloomington, our team customizes every design to meet your exact needs.
These flexible layouts allow you to maximize efficiency, save time, and create a multipurpose building that grows with your farming or business operation.
We install only the highest-quality insulation systems for post-frame buildings in Iowa and Illinois, ensuring superior moisture resistance and long-term protection. Our insulation helps prevent mold, mildew, and corrosion while keeping your shop clean, efficient, and easier to maintain. It also reduces heating and cooling costs for better long-term savings.
Whether you’re storing heavy machinery near Springfield, IL, or creating a climate-controlled workshop in Cedar Rapids, IA, our insulated shop buildings provide year-round comfort and performance.

Top-Quality Insulation for Year-Round Comfort
We always use the best materials on the market. The insulation we use expands after it’s placed, and perfectly fills every gap inside your walls, leaving your building completely and thoroughly insulated. Our insulation ensures consistent temperatures during the heat of summer and chill of winter, even through the Midwest’s unpredictable weather.
High-Quality Machine Sheds with Seamless In-House Service
Our team builds durable machine sheds with unmatched personal service and quality. We handle every step of the building process in-house, ensuring efficiency, reliability, and cost savings.
The cost of a machine shed varies based on size, design features, insulation, and site conditions. We offer custom quotes tailored to your specific needs and can help you find the right solution to fit your budget and usage goals.
Machine shed size depends on what you plan to store or use it for. Common sizes range from 40×64 to 80×160 feet or larger. We’ll work with you to determine the ideal layout and square footage based on your equipment, vehicles, and any workspace requirements.
While the terms are often used interchangeably, a pole barn is a type of post-frame construction, and a machine shed is typically a specific use case. Our machine sheds are post-frame buildings engineered for storing and protecting equipment, with optional features like insulation, lining, and overhead doors.
Timelines depend on project complexity, weather, and material availability. On average, most machine sheds can be completed within a few weeks once the site is prepared and materials are delivered. We’ll give you a clear schedule up front and keep you updated every step of the way.
You wouldn’t believe the amount of compliments I’ve gotten about the building. I will recommend Greiner Buildings to others and use them for future projects.
