Trading Spaces has always tested friendships and challenged neighbors to find out exactly how well they know each other, but there was one thing they could always count on -- they were in it together. Not anymore. Everything will change this spring when TLC's Trading Spaces reveals its most ambitious renovation yet: Trading Spaces: Home Free, a new eight-episode series that pits neighbor against neighbor in a tournament-style competition with new twists and turns, top secret surprises and fabulous prizes. Home is where the "start" is as homeowners race to redesign their neighbors' homes in the hopes of winning the ultimate grand prize -- their mortgage paid off. Sponsored by The Home Depot, the nine-hour series will premiere in a two- hour special on Sunday, March 7 from 7 PM to 9 PM, with subsequent airings weekly on Sundays at 8 PM ET/PT. Trading Spaces: Home Free will then culminate in a spectacular live reveal, as America finds out who wins their home free. Plus, one lucky viewer will also win his/her mortgage in a parallel online competition.
