House plans with large bonus rooms provide more square footage than a typical bonus room. They may be located over a three-car garage or utilize dormers and may include a bathroom or closet. Bonus rooms are considered unfinished space and are not included in the total square footage of a home unless the owner decides to finish the space upon building the home. Allowing you to finish the bonus room over the garage gives you the ultimate flexibility in creating the type of living space you want for a bedroom, office, media room, gym, etc.
