Make sure you have a clear idea of what the purpose of your new garage is. If it is to park your car in overnight, make sure you have plenty room to open the car door and comfortably walk around. Also ensure that any shelving is away from the space the car will occupy in case anything is accidentally knocked off a shelf. If you are using your garage mainly for storage, make sure you look at all the latest ideas for storage. Floor, walls and even the ceiling in a garagecan be used as effective storage areas.
