The 'Design Star' winner is challenged to a home makeover and must unveil the results to family and friends.

The competition heats up as eleven designers arrive in Hollywood to begin their quest to become HGTV's Design Star. Host Clive Pearse reveals their first challenge: to design rooms in the historic Hollywood home where they will be living. With the largest budget in Design Star history, the designers split into teams to design a massive living room, a dining room and three bedrooms, all in just 32 hours. Some designers shine, revealing amazing creativity, while others are unable to complete their vision.

The nine remaining designers face the classic Design Star White Wall challenge, but this time it takes place on a famous soundstage at Paramount Pictures. In this individual challenge, each designer must create a 10x10 room using only items purchased at a surprise location. Where innovation and creativity are key, some of the designers prove their potential, while others fall short.

In a brand new challenge, the designers compete to turn two messy garages into beautiful living spaces. Each of the two teams deals with unforeseen circumstances and personal conflicts. With a tight budget and only 22 hours, the remaining competitors not only have to please their clients but also the judges.

The six remaining designers are deployed to a military base where the drill is to turn two drab rooms into stylishly, comfortable entertainment spaces. However, both teams struggle with in-fighting that threatens to leave two deserving military families in the lurch.

In a Design Star first, the final four designers must work as a team to design and renovate a 10,000 square foot backyard. In their quest to create a modern oasis, tensions run high as the four strong voices struggle to be heard. When budget problems arise, all of their fates hang in the balance.

What would Design Star Hollywood be without a challenge involving celebrity clients? The three remaining designers face off as they decorate a home office for Kathy Griffin, a guest bedroom for Tiffani Thiessen and a baby's nursery for Jason Priestley. With 30 hours of work time and a budget of $20,000, only two designers will survive to compete for a 50-50 chance at winning their own show on HGTV.

The final two designers go head-to-head in the biggest Design Star challenge yet: making over a deserving family's entire home. Even with the help of a crew of carpenters, it's a daunting task that takes everything they've got. When the dust settles, the final two designers stand before the judges one last time, and a new Design Star is chosen.
