One of the first things to consider is the size of the garage. A 3 car garage requires a significant amount of space, so you'll want to ensure that the area you have available is sufficient. You'll also want to think about the style of the garage, including the type of roof, walls, and doors. A modern, sleek design can be a great way to add curb appeal to your home, while a more traditional design can provide a sense of nostalgia and familiarity.
