On this episode of Trading Spaces: Family, Laura Day laces up her white boots and organizes a psychedelic dance-party straight out of the 70's for the green team. A fog machine and disco ball complete the transformation from a plain basement to a swinging lounge. But will the tri-colored stripes on the wall dry before it's time to boogie? Over at the neighbors' house, designer Christi Proctor wants to help an all-purpose office blossom for the blue team. Christi brings some of the Cape Cod's beauty indoors as she arranges a vibrant garden room under a white trellis. Meanwhile, Carter Oosterhouse is swamped in carpentry world with not one but two very different banquettes. Does Laura Day's funky basement jive with the green team, and will the blue team stop and smell the flowers in Christi's botanical office? More importantly, will Joe ever learn what a banquette is?
