Trading Spaces has taken over the Northern Liberties section of Philadelphia, one of the new hip and trendy neighborhoods being reclaimed in the city. In this episode, we have four young urban pioneers ready to tackle two days of hard work. Designer Laurie Hickson Smith wants to create a basement lounge with the help of her homeowners. The only problem is that her homeowners are not that skilled in redecoration. In the other house Doug Wilson gives free reign to carpenter Carter Oosterhouse to build an armoire. And as unbelievable as it may seem, Doug is not happy with the result! Shocking! Paige might have to step in to mediate yet another disagreement on the set. Will Doug and Carter resolve their differences and will Laurie have to simplify her design? Tune in and find out.
