Jonathan and Drew Scott have renovated hundreds of family homes on three hit HGTV series: "Property Brothers," "Buying and Selling" and "Brother vs. Brother." But they have never faced clients as tough as the ones in their newest adventure, "Property Brothers at Home." The series follows the twins as they complete a massive renovation of their own home in Las Vegas just in time for a family reunion. Joined by older brother JD, the two redesign and rebuild the plain 5,000-square-foot Mediterranean home into a perfect family retreat. Customized features include 24-foot built-in shelves that showcase unique keepsakes from around the world, and outdoor "fun zones" like a water slide, a putting green, a theater and a swim-up bar.
