Garage floor plans with unfinished bonus space above the garage parking level or the available space above the parking area are very popular.
Your reasons for building a new garage are uniquely your own, so carefully evaluate your current and anticipated requirements regarding the structures dimensions. You will never regret having the additional bonus space for hobbies, future office, or even an additional future sleeping space for an older child. This bonus space can be finished at a later date keeping your initial cost of construction lower.
