Two Popular Rural Building Paths, One Important Decision
Across rural Ontario and beyond, two building types have captured the imagination of homeowners, farmers, and agritourism operators: the barndominium and the converted barn. Both offer open interiors, rustic aesthetics, and strong connections to the landscape. But when comparing barndominium vs converted barn, the two paths differ significantly in cost, performance, permitting, and construction complexity.
A barndominium is a new build designed to look and feel like a barn, while a converted barn transforms an existing agricultural structure into a modern, comfortable home. Each path has advantages and limitations. This guide lays out the technical and practical differences to help you choose the approach that best fits your goals, property, and long-term plans.
What Each Building Type Is
What a Barndominium Is
A barndominium is a custom-designed home that uses large-span structural systems-steel, post-and-beam, or engineered wood-to create open interiors with barn-inspired form and functionality. Because it's a new build, everything from the foundation to the envelope to the mechanical layout is engineered for year-round comfort.
Common features include:
- Tall ceilings and open-concept layouts
- Attached workshops or garages
- Durable metal or wood cladding
- High-performance insulation and air sealing
- Modern window, roof, and mechanical systems
- Flexible layouts that adapt over time
What a Converted Barn Is
A converted barn starts with an existing agricultural structure-timber frame, post-and-beam, stone, or steel-and transforms it into a home or mixed-use building. The character is already there, but significant structural and envelope upgrades are required to support occupancy.
Common characteristics include:
- Historic beams, timbers, and joinery
- Pre-existing roof lines and footprints
- Legacy foundation conditions
- Need for full mechanical, insulation, and structural upgrades

How They Work: Structure and Building Logic
Barndominium Logic
Because a barndominium is built from scratch, it benefits from structural clarity. Engineers can design:
- Straight, predictable load paths
- Strong spans for large, open rooms
- Foundation systems that match soil conditions
- High-performance wall and roof assemblies
- Proper ventilation and moisture control from day one
This makes barndominiums easier to bring to modern performance standards.
Converted Barn Logic
A barn conversion begins with the structural realities of whatever currently exists. This means:
- Assessing timber conditions (rot, insects, movement)
- Reinforcing or replacing aging beams or trusses
- Upgrading or rebuilding foundations
- Designing around heritage proportions and roof lines
- Preserving character while improving durability
Converted barns require more investigative work early in the project.
Performance and Energy Efficiency
Barndominiums
New construction makes it easier to achieve high-performance standards. You can design:
- Continuous exterior insulation
- Airtight layers without interruption
- Triple-glazed windows
- Properly vented roof assemblies
- Clean mechanical pathways for heat pumps and ERVs
Because everything is coordinated from the start, achieving long-term energy efficiency is straightforward.
Converted Barns
Energy efficiency in a converted barn is absolutely achievable but requires deliberate planning. The biggest challenges include:
- Irregular framing
- Existing air leakage paths
- Moisture-sensitive historic timber
- Limited wall thickness
- Uneven foundations
Exterior insulation strategies-"wrapping the barn"-are often the best approach because they preserve the interior timbers while improving thermal performance.
Cost Considerations
Barndominium Costs
Building new offers predictable cost management. While barndominiums are not "cheap builds," they often cost similar to or slightly more than conventional rural homes, depending on:
- Structural system (steel vs timber)
- Shop integration
- High-performance envelope choices
- Rural site work (well, septic, driveway, utilities)
The benefit is that money goes directly toward long-term durability and performance-not repairing old issues.
Converted Barn Costs
Barn conversions frequently cost more than new barndominiums because:
- Structural reinforcement is unpredictable
- Foundation upgrades are often required
- A full mechanical retrofit is necessary
- Insulation and airtightness must be delicately integrated
- Heritage materials may require specialty trades
Owners choose conversions for character and history, not low budgets.
Permitting and Approvals
Barndominiums
New homes follow standard rural permitting pathways:
- Zoning compliance
- Building permit
- Septic approvals
- Conservation authority review (site-dependent)
The process is clear-cut but can still take time due to rural bureaucracy.
Converted Barns
Barn conversions often require:
- Change-of-use approvals
- Structural engineering reports
- Heritage review (if applicable)
- Additional fire separation requirements
- Conservation authority clearance
Because the structure was never intended for residential use, the approval process can be more complex and lengthy.
Suitability for Rural Land
Barndominiums
Best for property owners who want:
- Clean building lines
- A predictable budget
- High energy performance
- A workshop integrated with the home
- A long-term, low-maintenance structure
Barndominiums are ideal for owners starting with raw rural land.
Converted Barns
Best suited for properties that already have:
- A structurally sound barn worth preserving
- Heritage character or sentimental value
- A desire to reuse historic materials
- A clear vision for adaptive reuse
- Adequate site access and space for upgrades
Conversions work best when the existing barn is truly worth saving-not just because it's already there.

Barndominium vs Converted Barn: Common Questions
Below are the most common questions rural property owners ask when deciding between a barndominium and a barn conversion.
Which is cheaper: a barndominium or a converted barn?
A barndominium is almost always more cost-effective. Converted barns require structural repairs, new foundations, and careful envelope upgrades. Owners choose conversions for character-not affordability.
Which one performs better in cold climates?
Barndominiums typically achieve higher performance more easily due to predictable framing and envelope design. Barn conversions can also achieve excellent performance with careful exterior insulation and airtightness strategies.
Which option is faster to build?
A barndominium is usually faster. Barn conversions require assessments, repairs, and detailed envelope integration that lengthen timelines. New builds follow more straightforward construction sequencing.
