There are many options out there when it comes to prefab garages, but there are few that compare to the Castle Mountain Garage. Garages don’t need to be ugly or boring, and the Castle Mountain is proof. If you’re looking for a garage that will give your property an upgrade in style and beauty, then this is your shed. 

The Castle Mountain Garage is another model in our line of prefab garages. This garage is built structurally similar to our A-Frame Garage but comes with an upgraded exterior. The end result is a garage that is both functional and beautiful.

Heavy Duty Flooring

One of the most important features of a garage is the floor. You want your garage floor to stand up to heavy use, so we’ve built a heavy floor. Our garage floors are rated for 288 pounds per square inch, plenty for a full-size truck, and more than 40% better than our competition.

Large Overhead Door

The distinct thing about this garage is the looks. We’ve given this garage some styling upgrades, like the archtop gable vents, faux shutters, and a half-glass entryway door. These subtle design additions give it a beautiful profile and appeal you wouldn’t expect from a garage.

Beauty may not be the first thing you think about when considering a garage or shed. However, at The Shed Center, we think that a shed’s value comes not just from its usefulness but also from its aesthetic appeal. We want to make the world a better place, and making quality, beautiful products is one way we do that.
