Frequently Asked Questions

How much does a shed cost?

The cost of an outbuilding depends on a few factors; first, the size of the building package. Larger structures cost more but are cheaper when considering cost per square foot. Second, building prices are determined by design, including the custom features that you select for your shed. Lastly, the price of steel at any time can fluctuate based on market performance. These factors combine to set your final price.

Why is a prefabricated building the best choice for a shed?

A prefabricated building provides the best value due to its design versatility, strength, durability, and efficient construction. A metal shed requires a high degree of customization, and a preengineered building kit from General Steel provides the functional and aesthetic components that make your shed your own.

What should I factor into my building budget?

Budgeting should be a careful process, as unexpected costs are sure to arise. Direct building costs such as atmospheric conditions, building use, and the price of steel are more easily accounted for than buying land, permits, and utilities. Be sure to factor in more than just the building itself.
