I need a 20x40 garage. What is the cost?
No matter what type of construction you are doing, to do an accurate estimation you have to consider many factors. Costs of material, labor, foundation, and finishes plus your chosen location all impact the cost of your building.
A garage that is 20x40 foot will have square footage in the amount of 800 feet. The material itself for the prefab garage will be about $6,400 if each square foot costs $8. It must be delivered to your job site. The cost for this will vary based on your location. You have to add in $4 to $8 a square foot for the laying of the foundation. If you need someone to help you construct the building, you will need to add in labor costs. After all these considerations, the cost will be between $16 and $20 per square feet, or $12,800 to $16,000 for a 20x40 garage.
However, you can reduce this cost by pouring your foundation and assembling your building yourself.
If you were building a traditional wooden framed garage, your costs would run an estimated $45 per square foot when you consider labor and materials. That would be a $36,000 total, much higher than a steel building.
