How Much Does It Really Cost to Build a Barndominium?

Ah, the barndominium—a unique mix of rustic charm and modern efficiency that’s become super popular in recent years.

And for a good reason! They’re trendy, practical, and, when done right, can be much more affordable than your typical home.

But here’s the kicker: the real cost of building a barndominium can vary a lot. I mean, really, it’s one of those “how long is a piece of string” questions.

I’ve seen people make it happen on a tight budget, but I’ve also seen costs spiral for others, especially when they want custom features.

So, let’s break down some of the biggest costs involved, and I’ll give you a few lessons learned from people who’ve taken on barndominium projects themselves.

Spoiler: it’s more than just four walls and a roof.

The Basic Structure: Shell Cost

The first big chunk of your budget is going to be for the “shell.” Think of this as the outer skeleton of your barndominium—walls, roof, and the foundation.

A lot of folks go for metal frames because they’re durable, pretty low-maintenance, and quick to put up. And, of course, metal gives it that classic barn aesthetic that makes a barndominium a barndominium.

Now, on average, you’re looking at anywhere from $20 to $70 per square foot just for the shell.

I know that’s a huge range, but it really depends on factors like location, materials, and the type of company you hire to do it.

Some companies specialize in barndominium kits, which can lower costs. But beware: kits often include just the basics. They might not cover things like doors, windows, or insulation.

In the end, if you’re planning a 2,000-square-foot barndominium, the shell alone could run you between $40,000 to $140,000.

But remember, this is only the start—there’s plenty more to think about!

Foundation and Slab Costs

Most barndominiums use a concrete slab foundation. These are sturdy, simple to pour, and keep the whole process pretty efficient.

But here’s where I learned the hard way: do not skimp on the foundation. Depending on your soil and climate, you may need extra prep work, and you definitely don’t want to cut corners here.

A solid foundation can cost anywhere from $5 to $10 per square foot, so for a 2,000-square-foot space, you’re looking at an additional $10,000 to $20,000.

It might sound like a no-brainer, but if you’re in an area with a lot of rain, clay soil, or even just extreme temperatures, get a professional assessment.

It’s an upfront cost that could save you from some serious headaches (and repair costs) down the road.

Interior Finishing: Where Costs Can Skyrocket

Now, the inside of your barndominium is where you can either keep things affordable or watch your costs balloon.

A lot of people think, “Oh, it’s just a big metal barn—how expensive could it be?” But the inside work is actually where you’ll spend the bulk of your budget.

Basic insulation, drywall, and minimal finishing might cost you around $30 to $60 per square foot.

But here’s where preferences really come into play. If you’re looking for that “modern farmhouse” look with reclaimed wood beams, shiplap walls, and custom cabinetry, prepare to pay a lot more.

Plus, let’s talk about insulation: metal buildings can get pretty hot or cold, so you want good insulation.

Expect to pay around $1,500 to $3,000 to properly insulate a 2,000-square-foot space, depending on the climate in your area.

Plumbing and Electrical: Hidden Costs That Add Up Fast

Here’s a bit of an inside scoop: many people forget to budget properly for utilities.

Unlike a traditional house, some barndominiums require specialized work for plumbing and electrical, especially if you’re in a more remote location.

Costs can also vary based on how close your barndominium is to local services. Running new plumbing or electrical lines to a rural location can add thousands.

Generally, you can expect to pay around $3,000 to $8,000 for basic plumbing, but if you want a high-end kitchen or multiple bathrooms, that cost will rise.

Electrical work can run around the same price range—so for both utilities combined, set aside at least $6,000, but more realistically, around $10,000 to $15,000 if you want extra outlets, upgraded lighting, or anything custom.

Permits, Land Prep, and Unexpected Expenses

One thing I always tell people: expect the unexpected. Barndominiums don’t get a free pass when it comes to building permits, inspections, or zoning requirements.

Depending on where you live, permits can range from a couple of hundred dollars to a few thousand.

And if you’re buying raw land, you might need to clear trees, level the ground, or even install a septic system. Land prep alone can easily cost $5,000 to $15,000.

And here’s my favorite piece of advice—plan for a contingency fund. No matter how well you budget, unexpected costs will pop up.

Something as simple as upgrading to higher-quality windows or adding a porch can add thousands. I usually recommend setting aside at least 10-15% of your total budget for surprises.

So… What’s the Final Tally?

So, let’s break it down. For a basic, no-frills 2,000-square-foot barndominium, you could be looking at:

• Shell: $40,000 to $140,000
• Foundation: $10,000 to $20,000
• Interior finishes: $60,000 to $120,000
• Plumbing/Electrical: $10,000 to $15,000
• Land prep and permits: $5,000 to $15,000

Total: Anywhere from $125,000 to $310,000.

That’s a pretty big range, right? The truth is, building a barndominium can be as budget-friendly or luxurious as you want.

Just remember, there are plenty of ways to cut costs, like doing some of the finish work yourself or sticking with simple materials.

But don’t skip the essentials like a solid foundation and good insulation—they’ll save you a lot of money and stress in the long run.

Building a barndominium is one heck of a journey. It can be challenging, but for so many people, the end result is worth every penny.

Just make sure you know what you’re getting into, and go in with a solid budget and a little bit of flexibility!
