I understand your concerns because I was in a similar position and ended up researching a lot before making my choice. I came across a two story one car garage that was prefabricated and was intrigued by the design flexibility and the space it offered. What stood out for me was the balance between cost, build quality, and customization potential. The prefab process generally means reliable standards since parts are made in controlled environments, which lessens weather-related delays or quality fluctuations. The second story space is usually designed for storage or a workshop, depending on your needs, and that extra level really helps to maximize usable area without taking up much yard space.
