What Is a Barndominium?

What Is a Weld-Up Building?

A barndominium — or "barndo" for short — is a hybrid structure that combines a metal building shell with the comforts of a modern home. Originally inspired by converted barns, today’s barndominiums are custom-designed residential or live/work spaces built using welded steel framing and metal siding, offering durability, flexibility, and affordability.
Barndominiums typically feature:

• Spacious, open floor plans
• High ceilings and wide spans (thanks to steel construction)
• A mix of residential and functional areas, like living quarters + workshops or garages
• Low maintenance exteriors with energy-efficient insulation
• Full plumbing, electric, HVAC, and custom interior finishes

🛠️ Weld-Up vs. Pre-Fab:
Most barndominiums built by Waco Mobile Welder use a weld-up steel frame, meaning the structural components are cut and welded together on-site. This allows for complete design freedom and a more solid structure than typical bolt-together kits.

Whether you're building your dream country home, a hunting lodge, a shop-house combo, or a guesthouse on your land, barndominiums offer the best of both worlds: strength and simplicity of steel with the custom features of a modern home.

​And yes — you can live in one full time. In fact, many people prefer it.

A weld-up building is a type of metal structure that’s built by cutting and welding raw steel components on-site, rather than assembling pre-engineered pieces with bolts. This method offers more flexibility, strength, and customization than traditional bolt-together kits.

​🏗️ Key Features of Weld-Up Buildings:

• Custom-Cut Steel: Beams, columns, and trusses are measured and welded during construction — no pre-punched holes or fixed layouts.
• Stronger Joints: Welded connections are more rigid and seamless than bolts, offering better support for heavy loads or large open spans.
• Design Freedom: You can tailor the size, layout, and framing style to fit your exact needs, whether you're building a barndominium, shop, garage, warehouse, or livestock shelter.

🔧 Weld-Up vs. Bolt-Up:

• Weld-Up:
  • Built on-site by a skilled welder
  • Fully customizable structure
  • Stronger joints and fewer limitations
  • Requires experienced labor
• Bolt-Up (Pre-Engineered):
  • Factory-made pieces assembled with bolts
  • Faster for simple builds, but limited in design
  • May require long lead times for ordered components

At Waco Mobile Welder, we specialize in weld-up metal buildings because they offer our clients strength, adaptability, and cost efficiency — especially when building on rural land or customizing a home/shop combination.

​If you want something solid, lasting, and truly made for you — weld-up is the way to go.

Are Barndominiums Cheaper to Build Than Traditional Homes?

Yes — barndominiums are typically much more affordable to build than traditional stick-frame homes, often costing 30–50% less per square foot, depending on materials, layout, and finishes. That’s one of the main reasons they’ve become so popular across Texas and beyond.

​💰 Why Barndominiums Are More Cost-Effective:

• Steel construction is faster and simpler
  Weld-up frames go up quickly with fewer trades involved, reducing labor time and overhead.
• Open floor plans reduce framing costs
  The wide-span design of metal buildings allows for fewer interior load-bearing walls.
• Exterior and roofing are built in
  Metal siding and roofing are installed as part of the building’s structure — no extra framing or shingles needed.
• Lower long-term maintenance
  Steel is termite-proof, fire-resistant, and far more durable in extreme weather than wood-framed structures.
• Multi-use functionality
  Many barndominiums combine living space with garages, shops, or barns — so you get more for your investment in one structure.

At Waco Mobile Welder, we specialize in weld-up barndominium frames that give you full customization without the markup of a pre-fab kit or builder package. You decide the size, layout, and purpose — we bring the steel and the skill to make it happen.

​Do I Need a Foundation for a Metal Building?

Yes — every metal building needs a solid foundation. Whether you're constructing a barndominium, shop, garage, or storage building, a proper foundation anchors the structure, ensures long-term stability, and keeps everything level, square, and safe.

​🧱 Types of Foundations for Metal Buildings:

• Concrete Slab Foundation (most common)
  A flat, reinforced concrete surface that supports the entire structure. Ideal for barndominiums and weld-up buildings, offering durability and clean finish floors.
• Pier Foundation
  Concrete piers poured under each column, often used for smaller metal buildings or uneven terrain. Sometimes combined with beams or skirting.
• Perimeter Footing + Slab Combo
  A concrete footing around the perimeter for walls and support columns, paired with a slab for the floor. Excellent for load-bearing and stability.

🛠 Why Foundations Matter:

• Prevents settling, shifting, or cracking
• Anchors welded steel columns and framework securely
• Meets building codes and inspection requirements
• Adds value and durability to your structure

At Waco Mobile Welder, we work directly with your contractor or concrete crew to ensure your weld-up metal building is anchored to a strong, level foundation — because solid steel still needs a solid base.

​How Long Does It Take to Build a Barndominium?

The timeline for building a barndominium can vary based on size, design, and the complexity of your interior build-out — but in general, most barndominiums can be completed in as little as 4 to 6 months, and sometimes even faster.

​🕒 Typical Barndominium Build Timeline:

1. Site Prep & Foundation – 1–3 weeks
   Grading, clearing, and pouring the concrete slab or foundation.
2. Weld-Up Steel Frame Construction – 1–3 weeks
   Our team at Waco Mobile Welder cuts, fits, and welds your custom steel frame directly on-site. Welded buildings go up faster and stronger than traditional wood frames.
3. Roofing, Siding & Shell Completion – 2–4 weeks
   Metal panels, insulation, windows, and doors are installed. At this point, the building is “dried-in.”
4. Interior Build-Out – 8–16 weeks
   Includes plumbing, electrical, HVAC, drywall, flooring, cabinetry, and custom finishes — timing depends on design complexity and contractor availability.

⚡ Faster Than Traditional HomesCompared to traditional stick-built homes — which often take 8–12 months or more — barndominiums are significantly faster to build, especially when you choose a weld-up construction method.
And because you’re combining home + shop + garage in one structure, you’ll save time and money by streamlining your entire build process.

​Can You Customize the Layout of a Metal Building?

Yes — one of the biggest advantages of a metal building, especially a weld-up build, is complete layout flexibility. Unlike pre-engineered bolt-together kits that limit your design to factory specs, welded steel framing allows for total customization of both your exterior and interior layout.

​At Waco Mobile Welder, we fabricate and assemble your steel structure on-site, which means we can tailor it to your specific needs, property layout, and lifestyle — not the other way around.

🏠 What Can Be Customized?

• Overall size and shape (length, width, height, pitch)
• Interior floor plan (open concept, walls, rooms, lofts, etc.)
• Door and window placement
• Add-ons like porches, breezeways, lean-tos, or attached shops
• Second stories, mezzanines, or bonus storage lofts
• Garage bays, RV ports, horse stalls, and more

🔧 Weld-Up = Design FreedomBecause the structural steel columns and trusses are welded on-site, you’re not locked into fixed spacing or dimensions. We can adjust framing to accommodate your ideas — whether it’s a massive open-concept living room, a high-clearance workspace, or a mix of living and working zones in one structure.

​If you’re building your dream barndominium, workshop, or multi-use building, our job is to make the layout work for you — not the other way around.

Are Barndominiums Energy Efficient?

Yes — barndominiums can be highly energy efficient when built and insulated properly. Despite their steel structure, modern barndos are built to meet or exceed residential energy standards — often outperforming traditional homes in efficiency and long-term savings.

​The key lies in the quality of the insulation, proper building orientation, and the use of high-efficiency HVAC systems and windows.

🌡️ Energy Efficiency Features of a Well-Built Barndominium:

• Spray Foam Insulation
  Seals gaps and provides a high R-value barrier against Texas heat and cold, perfect for metal structures.
• Continuous Roof & Wall Insulation
  With fewer seams than wood framing, metal buildings can be easier to seal and insulate thoroughly.
• Reflective Metal Roofing
  Light-colored metal roofs reflect sunlight, reducing attic temperatures and overall cooling costs.
• Open Floor Plans
  Make airflow and zoning more efficient, especially with modern HVAC systems.
• Efficient Windows & Doors
  Double-pane, energy-rated windows and insulated doors help maintain indoor comfort with less energy use.

💡 Welded Builds Support Smart Energy DesignWith a weld-up barndominium, you get full control over your insulation choices and energy-efficient upgrades from the ground up. This lets you design a building that’s not only tough and beautiful — but also cost-effective to live in long-term.

​Lower energy bills, better comfort, and less waste — barndominiums can do it all.
