Overview: It's all about girl power in this Boston episode. Designers Laurie Hickson-Smith and Genevieve Gorder race against the clock (and against each other!) to create two new bedrooms for a pair of 12-year-old neighbors. They get some help from the girls' parents and from carpenter Ty Pennington, who assembles a trundle bed in one room and a curtained sleep area in the other. Will it pass the 12-year-old taste test?
