The Short Answer
Yes — but not as much as the internet tells you. Barndominiums can cost 20–40% less per square foot. A finished barndominium in Ontario costs $175–$300 per square foot.
Head-to-Head: 2,000 sq ft in Ontario
| Category | Barndominium | Traditional |
|---|---|---|
| Foundation | $30,000–$50,000 (slab) | $50,000–$90,000 (basement) |
| Structure | $50,000–$90,000 | $80,000–$140,000 |
| Mechanical | $55,000–$90,000 | $50,000–$85,000 |
| Insulation | $18,000–$30,000 | $15,000–$25,000 |
| Interior | $70,000–$130,000 | $80,000–$150,000 |
| Total | $243,000–$430,000 | $300,000–$535,000 |
Where Barndominiums Save: Foundation (30–45%), Shell (35–40%), Speed (indirect)
Where They Cost MORE: Insulation (15–25%), Mechanical (5–15%), Fire separation ($5K–$15K)
The Real Math: Total Cost of Ownership (10 years)
| Factor | Barndominium | Traditional |
|---|---|---|
| Build cost | ~$350,000 | ~$425,000 |
| 10-year total | $412,000–$456,000 | $487,000–$525,000 |
A properly planned barndominium saves $30,000–$70,000 over 10 years.
The Bottom Line
The real savings are in foundation and structure. Everything else is comparable or slightly more. Shell price is not build price.
