Which One, Two and Three Car Garages Do We Recommend?

Browse popular garage sizes, but any size is possible and customizable

Below we’ve provided our most popular garage sizes as recommendations for your project, but every General Steel building design can be tailored to your specific needs. That includes designing your garage based on your location. Many steel building distributers fail to take these important factors into consideration. General Steel ensures your garage will satisfy all of your local codes and guidelines, including seismic activity, wind loads and snow loads.

One-Car Garage Kits

If you are looking to shelter a single vehicle, our one-car garage kits are ideal. General Steel one-car garage kits have room to spare, which ensures that you’re able to comfortably get in and out of your vehicle while also leaving space for any smaller toys or future valuables. Sizes we recommend for a one-car garage:

12′ x 24′ One Car Garage KitInfo and Cost Considerations

General Steel offers several choices for 2-car detached or attached garages; sizes we recommend are:

Three-Car Garage Kits

In a survey we conducted with over 20,000 garage shoppers, the most common need were three-car garage kits. Most of those that responded to the survey used the three-car garage kit to house two vehicles and have plenty of extra space for storage. Other uses of three-car garages included RV storage, company fleet storage, classic car storage or constructing their “mancave”. We recommend a 24x36 kit or 30x40 kit for your three-car garage. Our top three-car garage recommendations are:

Why Your Garage is a Good Investment

Experts agree, adding a garage could increase your home’s value.

A well-constructed garage can be a significant boon to the value of your home. According to a study by Florida State University, homes with a regularly sized garage were valued at a 13 percent higher price than the same home without a garage. And for houses with an oversized garage, the increase in value was 14 percent. Those gains in home value are in addition to the benefits of sheltering expensive vehicles and supplies. Of course there’s a cost to build a garage, but General Steel garage kits has proven to be a reliable and valuable asset for many customers.
