The final cost of a 40×60 metal building with slab changes based on its use—storage, commercial, residential, or agricultural. Custom features such as HVAC, insulation, and interior finishing can increase price from $50,000 to $90,000. Define your purpose clearly to avoid under- or overbuilding.
1. Agricultural Use:
Barns and farm buildings often skip insulation or luxury finishes. A basic agricultural 40×60 building with slab can cost $50,000–$60,000. Durable panels and ventilation matter more than interiors, helping keep costs low.
2. Residential Garage:
For garages, add insulated panels, doors, electricals, and HVAC. This raises cost to $65,000–$75,000. Epoxy-coated slabs and finished interiors are popular for attached or detached garages used as hobby or auto spaces.
3. Commercial Office:
Office builds need HVAC, insulation, plumbing, and interior framing. Total cost ranges from $70,000–$90,000. Local code upgrades for fire exits and ADA compliance can add several thousand to your estimate.
4. Workshop or Studio:
Workshops may include loft storage, extra outlets, lighting, or reinforced slab for machinery. These features raise your budget to $65,000 or more. Consider utility line installation fees too.
5. Event or Recreational Space:
Buildings used for events, gyms, or game areas need flooring, restrooms, and insulation. These factors bump the cost to the $80,000+ range. Design early to avoid rework or budget overruns.
