Barndominium Construction Guide: Costs, Components & Building Types for 2025

Barndominiums—often called "barndos"—are becoming one of the most popular alternative housing options in 2025. Combining the rustic charm of a barn with the modern comforts of a home, barndominiums offer affordability, flexibility, and style. Whether you’re building one as a primary residence, a weekend getaway, or a multifunctional workshop-home combo, understanding barndominium construction is key to getting the most value out of your build.

In this guide, we’ll break down the best type of building for a barndominium, essential components, and the latest construction cost trends to help you plan your project with confidence.

What Is Barndominium Construction?

Barndominium construction refers to building a residential home that’s based on the framework of a barn or barn-style structure. Originally popular in rural areas and among horse owners, the modern barndo has evolved into a stylish, energy-efficient, and highly customizable dwelling.

Most barndominiums are built using metal or steel frames, but wood-framed structures are also common, especially when budget or regional building codes come into play. The process typically involves:

1. Laying a concrete slab foundation

2. Erecting the framing structure (metal or wood)

3. Adding roofing, siding, insulation, and interior finishes

Best Type of Building for a Barndominium

So, what’s the best type of building for a barndominium?

The clear winner for most homeowners in 2025 is metal or steel frame construction. Here’s why:

1. Durability: Steel is resistant to rot, pests, and fire

2. Low maintenance: No need to worry about termites or warped wood

3. Design flexibility: Wide-open interiors with fewer load-bearing walls

4. Speed: Metal building kits can reduce construction time significantly

While pole barns and wood-framed buildings are still used—especially in DIY or low-budget builds—they may require more maintenance over time. For long-term durability and resale value, a steel building is often the best type of building for a barndominium.

Key Components of a Barndominium

A successful barndominium construction project involves several essential components. Each part plays a role in comfort, function, and cost:

1. Foundation

1. Most barndos are built on concrete slabs, offering a stable and moisture-resistant base.

2. In some regions, pier and beam foundations may be used.

2. Framing

1. Steel frames offer structural integrity and fire resistance.

2. Wood framing may be cheaper but is more prone to rot and insect damage.

3. Roofing and Siding

1. Metal roofs and siding are common, offering durability and a clean aesthetic.

2. Options include standing seam metal panels, corrugated steel, or insulated panels.

4. Insulation

1. Closed-cell spray foam or rigid board insulation is often used to regulate temperature and improve energy efficiency.

5. Interior Layout

1. Barndos usually feature open floor plans, lofts, and high ceilings.

2. Integration with a garage, shop, or storage area is common.

6. HVAC, Electrical, and Plumbing

1. These systems are just like any traditional home and should be installed by licensed professionals to meet code requirements.

Barndominium Construction Cost in 2025

One of the biggest reasons people choose a barndominium is the cost. While prices have risen slightly due to inflation and material demand, barndos still offer great value compared to traditional homes.

Pro Tip: Always budget 10–15% for unexpected expenses, especially if you're building in a rural area where utility access might be limited.

Popular Barndominium Floor Plans

Barndominiums are all about versatility. Here are some trending layouts:

1. 3-bed, 2-bath family homes with an attached garage/shop

2. Single-story open concepts for aging in place

Whether you’re building 1,500 or 3,500 square feet, barndos can be tailored to fit your lifestyle and land.

DIY Barndominium Kits vs. Hiring a Builder

Thinking of doing it yourself? Here’s a quick comparison:

DIY Kits

Lower cost
More control over finishes
Requires time, tools, and experience
You’re responsible for permits and inspections

Professional Builder

Faster, turnkey process
Licensed work and code compliance
Higher overall cost
Less customization (depending on builder)

Many homeowners opt for a hybrid approach—purchasing a shell kit and hiring pros for the mechanicals and finish work.
