Besides a brand new room, there are plenty of other benefits that come with remodeling garages. First and foremost, if you simply update your garage with new flooring, windows, insulation or garage organizers, you instantly increase the value of your home. While you may not see a 100% return on investment the day you sale, you will surely get more than you would have before the garage renovation.
A garage remodel is usually much cheaper than a home renovation because the foundation, roof, and walls are already built. Many garages also have electrical and plumbing installed to some extent. The actual cost of a garage remodeling project, however, depends on what the renovated space will be used for. While a new home gym won't require much in the way of amenities, converting a garage to an office, apartment, or bedroom requires adding significantly more creature comforts.
