3-Car Garage Plan refers to detached garages designed to store up to three automobiles. A wide range of floor plans is available when garage doors, bays, size, and style are considered. Three small overhead doors, or one large door and one smaller door, may be used in the 3 Cars Garage Plan. They may also have one or more bays with a door at the back, forming a Drive-Thru garage bay. The depth of the garage bays contributes to their usability and functionality. Deeper and taller bays are ideal for oversized vehicles such as trucks or SUVs, and some are even deep enough to store boats.
