Header: Our Basement is "Finished". Family finished their basement with a slide, swing, and on a budget. I would change the color of the rooms, but awesome ideas!
Teens may not care about a lot of floor space, so seating like this Cushy Lounge Sectional from PBteen creates a study nook and hangout area worthy of having friends over.
