Often located above the garage, the bonus room is normally designed and framed, to be finished at a future date. The bonus room could be completely private, with a separate stairway leading up from the garage. Or the bonus room could be located at the end of the upstairs hall, easily accessed from other bedrooms. The bonus room floor plans could be finished as a playroom, an art studio or even a bedroom for a noisy teenager. Or how about adding a bath and renting out the space to a single working adult or a college student?
