When you’re planning a new custom building in Iowa or Illinois—whether it’s a post-frame shop, a steel-frame COMMERCIAL project, a GARAGE building, or a SHOME®, there are three things you never want to waste: TIME, PEACE OF MIND, and MONEY.
At Greiner Buildings, our design-build process was created to protect all three. Instead of juggling multiple contractors and hoping everything lines up, you get one dedicated partner guiding you from start to finish.
We combine in-house designers who developed our quoting and designing software, experienced builders, and a FREE 3-D Designer Tool to make your project faster, easier, and more cost-effective.
WHAT IS DESIGN-BUILD?
Traditional building often requires hiring an architect, bidding out the plans, juggling subcontractors, and managing communication between all parties. That process is slow, expensive, and stressful.
Design-build flips the script. Instead of managing multiple companies, you work with one team that handles your project from concept to completion.
At Greiner, our design-build process means:
- One contract. One partner for design and construction.
- One team. Designers and builders collaborating from day one.
- One timeline. Streamlined communication that keeps projects moving.
It’s a smarter way to build—ideal for Farm shops, Hobby Garages, and Equestrian Barns, as well as residential SHOME® homes designed for everyday living.
TIME: ONE TEAM, ONE TIMELINE
With design-build, you don’t have to coordinate between an architect, a builder, and a dozen subcontractors. Our in-house designers and crews work together from the start, which means fewer delays, fewer surprises, and a timeline you can actually count on.

STRESS: CLEAR COMMUNICATION AT EVERY STEP
Building something new should be exciting—not overwhelming.
With our design-build process:
- You’ll have one point of contact from start to finish.
- Our team walks you through each decision step by step.
- You’ll always know what’s happening, who’s on-site, and what’s next.
From Machine Sheds to Custom Workshops and Storage Buildings, we keep every project clear, simple, and stress-free.
MONEY: SMARTER PLANNING, BETTER VALUE
Because our designers and builders collaborate from the start, we spot potential issues early and solve them before they become costly problems.
That means:
- Fewer change orders (the #1 budget-buster in construction).
- Value-engineered solutions that save money without cutting quality.
- A final build that stays on budget and delivers long-term value.
Our design-build approach is trusted across the Midwest—powering Livestock Barns, Commercial Facilities, Event Centers, and barndominium-style SHOME® homes built to last for generations.
