What’s the cost to build a 10,000 sq ft steel cold storage (cooler vs. freezer)?

For budgeting, a 10,000 sq ft cooler often pencils near the lower–middle of the above range; a freezer sits higher due to thicker insulation, floor heat, and heavier refrigeration. A Canada-focused cold room guide cites $100–$300 per sq ft as a typical planning band, with smaller rooms at the high end.
