Find out what it took to build the first-ever real-life Barbie DreamHouse with unseen footage of each challenge, new interviews, outtakes, trivia and takeaway.

Christina Hall and James Bender take on Michel Smith Boyd and Anthony Elle. Then the four finalist spaces compete at a "Pink Carpet" event. One space is voted the winner, and a fan wins a stay in the DreamHouse. Appearance by Barbie star, Margot Robbie!

Keith Bynum and Evan Thomas transform the front exterior, adding a gigantic handle on the roof, to compete with Brian and Mika Kleinschmidt's backyard pink party pad. Actress Marsai Martin joins the judges to choose one team to move on to the finale.

Jonathan Knight and Kristina Crestin must create Barbie's iconic bedroom suite, as they battle Alison Victoria and Ty Pennington, who are building a first-ever den for Ken. Special guests Allison Holker Boss and ET's Nischelle Turner join the fun.

In the premiere, Ashley and the competitors will take an inspiring trip to Mattel headquarters and get a mind-blowing Barbie surprise. Kicking off the competition, real estate and design power couple Egypt Sherrod and Mike Jackson (Married to Real Estate) will face-off against expert builder Jasmine Roth (Help! I Wrecked My House) and Food Network's Antonia Lofaso (Beachside Brawl) for a first-floor showdown.
