Host Matt Blashaw challenges Rizal and Mahana Coleman and their three kids to convert their huge run-down backyard into an outdoor oasis. Matt and landscape designer Joan Grabel will inspect the new space and estimate its cost. If their estimate is more than what was actually spent, the Colemans win the difference in cash!! Rizal and Mahana's yard is 7000 square feet, but it's divided in two by a huge row of hedges. They haven't put any time or money into making the space functional, so it's sat neglected for five years. Now, they're ready to tackle the job, but haven't ever landscaped a yard before. Also, Rizal and Mahana own their own business, and work together all the time already. Will working together 24/7 to complete the renovation be too much to bear?
