A garage apartment is essentially an accessory dwelling unit (ADU) that consists of a garage below and living space over the garage. This type of design offers garageowners extra space to store their stuff in one section and host guests, parents or older kids in the other section. COOL Garage Plans offers unique garage apartment plans that contain a heated living space with its own entrance, bathroom, bedrooms and kitchen area to boot. You can use any of our building plans to construct a brand-new unit or add extra living space to your existing property. Plus, our garage plans with apartments are available in one, two, and three car configuration, which you can choose from based on your preferences.
