Post-Frame Building Kits: Pros, Cons & Budget Checklist

June 25, 2025

There’s something deeply satisfying about building something with your own two hands. Whether it’s a backyard fence, a new deck, or a full-on workshop, that sense of ownership runs deep. So it’s no surprise we get a lot of calls from folks asking, “Can I just buy a post-frame building kit and do it myself?”

The short answer? Yes—you can. But the better question might be: Should you?

Before you start pricing out post-frame building kits or watching time-lapse videos of barns going up in a weekend, let’s take a step back and look at the whole picture. Because while kits can be a smart, cost-effective option for the right kind of project, they’re not always the slam-dunk they seem at first glance.

This guide will walk you through the real pros, the real limitations, and the hidden costs you need to budget for. And if you’re not quite sure whether you need a kit or a custom build? Stick around to the end—we’ll help you figure that out too.

What Is a Post-Frame Building Kit?

A post-frame building kit is a pre-packaged set of materials you can order and assemble yourself (or with a little help from friends). Think of it as the IKEA version of a barn or garage: trusses, posts, fasteners, siding, roofing—all neatly bundled and delivered to your property.

Most kits come with detailed assembly instructions, and many suppliers will walk you through your options: size, colors, door placement, and roof style. These kits are popular with DIYers, farmers, and small-business owners looking for a quick and budget-friendly way to add storage or workspace.

The Upside: Why Kits Appeal to DIYers

There’s no denying the appeal of building it yourself—especially if you’re handy, have a bit of time, and love a good weekend project.

Cost Savings:

One of the biggest reasons people look at post-frame kits is price. Since you're not paying for labor, you can save thousands—sometimes even tens of thousands—depending on the size and scope of the project. A basic 24x36 garage kit might cost $12,000–$20,000 for materials, compared to $35,000+ for a professionally built version.

Speed of Delivery:

Because many kits are standard sizes and styles, they’re usually in stock or quick to manufacture. That means you can often get your materials delivered within a few weeks.

Simplicity (on Paper):

Post-frame construction is less complicated than traditional framing. That’s why it’s such a popular method in the first place. With clear plans and a level site, a kit can go up relatively quickly—especially if you’ve got building experience.

Satisfaction:

There’s a real sense of pride in saying, “I built that.” For DIYers, that’s worth a lot.

The Trade-Offs: What Kits Don’t Always Include

Here’s where the story shifts. Because while kits sound great in theory, they come with trade-offs that aren’t always obvious until you’re knee-deep in sawdust.

Limited Design Flexibility:

Kits are usually based on stock designs. That means fewer layout options, fixed door/window locations, and fewer finish choices. If you want a custom roof pitch, extra height, or stone wainscoting? That’s not always an option without going full custom.

Hidden Labor Costs:

Yes, you’re not paying a builder—but someone still has to do the work. If you’re not fully DIY-savvy, you might end up hiring a crew or subcontractors for certain parts (like concrete, electrical, or insulation), which quickly eats into those savings.

Permit and Code Hurdles:

Depending on your location, a building permit may be required—and not all kits come engineered to meet your local code. You’ll need to make sure your kit meets wind, snow load, and zoning requirements before you break ground. And if you don't? You could end up with a stalled project or costly retrofits.

Site Prep Isn’t Included:

Kits usually cover just the structure itself. You’ll still need to factor in costs for grading, concrete pads or piers, equipment rental, and debris removal—none of which come shrink-wrapped with your trusses.

Time and Tools:

Even a “simple” build can take weeks for someone without experience. You’ll need the right tools (like post-hole diggers, lifts, nail guns), plenty of free time, and often a second set of hands. If you're planning on tackling this alone, be honest with yourself about your skills and schedule.

When Does a Kit Make Sense?

For smaller structures like sheds, single-bay garages, or ag outbuildings where appearance and long-term use aren’t top priorities, kits can be a solid choice—especially if you’ve built things before and enjoy the work.

They’re also great if you:

  • Already own construction tools and equipment

  • Have help from skilled family or friends

  • Don’t need fancy finishes or plumbing/HVAC

  • Want to save upfront on labor costs

Just remember: the more complex your needs, the more value a professional builder brings to the table.

Post-Frame Building Kit vs. Custom Build: What’s Right for You?

Let’s say you want a place to park your camper, store your tools, and maybe add a heated workbench area. Can a kit get you there? Maybe. But it depends on how much time, effort, and flexibility you’re willing to trade for cost savings.

Custom builds come with big advantages:

  • Tailored design to your exact needs

  • Code compliance and stamped engineered drawings

  • Turnkey delivery with a predictable timeline

  • Expert project management (so you’re not Googling what flashing is at 11PM)

They also give you peace of mind. Our clients often tell us the biggest benefit of working with a team like Dutch Builders wasn’t just the end product—it was the smooth process that got them there.

Budget Checklist: Planning Beyond the Kit Price

If you’re pricing a post-frame building kit, make sure to include the full picture. Here’s what should be on your checklist:

✅ Kit Materials (structure, siding, roofing)
✅ Delivery Fees
✅ Site Preparation (clearing, grading, gravel)
✅ Foundation or Concrete Slab
✅ Permits and Engineering Fees
✅ Tools and Equipment Rental
✅ Labor (yours or someone else’s)
✅ Electrical, Insulation, and Interior Finishing (if needed)

By the time you factor in everything, that $20,000 kit could easily become a $35,000–$45,000 project. And if your time is valuable or your project is complex? You might come out ahead with a professionally built structure.
