To take your Horizon Structures’ one car garage to the next level—literally—put a second floor on it! The two-story 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.
