Types of 30×40 Garage
Because all construction projects these days give builders multiple options, you should not be surprised to discover that the best way to begin your project is to identify the type of structure that best suits your budget, home’s design and needs. Here are the 4 most common 30 x 40 foot garage options:
Traditional type with straight walls.
Also called a “standard” garage, traditional garages are easy to identify because they serve no purpose other than to house one or more automobiles.
These structures have no additional features thus they are bare bones – and they’re the simplest to construct, no matter how many cars you have.
Further, if your vehicles are SUVs, look for plans or kits that expand on the garages height and width.
Quonset type garage
These are the easiest to identify due to their unique shapes and histories based on Quonset huts used to house GIs, operations and storage facilities on military installations.
Because they are fabricated of steel, these structures are easy to customize and can be custom-built to include features like vents and skylights.
Durable, affordable and highly protective, you don’t have to sacrifice style. Since steel is available in myriad colors these days, you don’t have to settle for the standard grey for which military huts are known.
These are most likely to be “straight wall” buildings offering maximum interior space and offering multiple exterior design and color options.
Like Quonset huts these straight wall garages are super strong and durable, won’t harbor termites, they’re fire resistant, easy to maintain and if you opt for recycled steel, your finished garage will be a model of earth friendliness, too.
The number of steel prefab kits on today’s market offer you a vast number of options.
Wood is most often chosen for aesthetic reasons and if you’re a trend watcher, you probably know that timber garages are back in style, reflecting the past when all garages were built only of wood.
In addition to being a sturdy, durable material wood can insulate an enclosure and many prefabs, built-from-scratch and kits are considered environmentally friendly because wood is a sustainable resource.
Downsides associated with this type of garage are the potential for termites, mold, mildew and even treated lumber can be flammable so you could wind up paying more for homeowner’s insurance if you choose this style when you build.
Attached vs detached? That is the question
While there are kits available for 30- x 40-square foot detached and attached garages, your home’s layout, property limits and zoning restrictions could force you to choose only one configuration, so it’s good to know the pros and cons of both types of garages in the event you are given a choice.

Mistakes homeowners make when adding or replacing existing garages
- Compromising on quality materials or labor. All costs considered, a steel garage is likely to outlast any wood structure and because even the worst steel will hold up better than some woods, you don’t want to face years of maintenance for yourself or pass the burden down to whomever buys the house when you sell.
- Ignoring aesthetics. In your quest to save cash by adding a 30- x 40-foot garage, it can be easy to compromise the home’s exterior look. For this reason, wood garages often have an edge because they deliver on more design options. That stated, today’s steel garages are getting more versatile and beautiful every day.
- Doing the job without proper skills or training. Not only do zoning laws exist in most communities but community regulations can require professional licensing by whomever does the build. Neighborhood associations are extremely picky about adding exterior features because changes can impact the value of homes on the entire block. If you live in a rural area that doesn’t require you to adhere to these types of standards, you’re in luck!
