To take your Horizon Structures’ one car garage to the next level—literally—put a second floor on it! The one car, two-story garage configuration gives you the chance to save space by building up, instead of out. The upper level is tall enough to stand in and is accessible by our full-size staircase, providing an attractive and out-of-the-way place to store holiday decorations, the kids’ sleds, and your golf clubs. What’s even better about our structures is that they are 100% PORTABLE buildings! Your neighbors won’t believe it. So peruse our gallery, and call us at 888-447-4337 when you’re ready to discuss your own single car, two-story prefab garage.
