One might think combining business with family would create an unworkable dynamic for brother and sister Steve and Leanne Ford, but that couldn't be further from the truth. "We feel comfortable pushing each other to new limits to get the most out of each design," says Leanne, who works with her sibling to enliven older Pittsburgh homes with beautiful, unique custom renovations. An interior designer, Leanne creates new looks and floor plans for the homes, many of which are a bit out of the ordinary and unconventional. Steve is a licensed contractor with "MacGyver-like" carpentry skills. He's adept at executing his sister's vision to maximize the charm and functionality of the properties.

Twin brothers Jonathan and Drew Scott aim to help couples find fixer-uppers and transform them into dream homes. The brothers use state-of-the-art imagery programs to unveil their plans for how the properties will look after the transformation. But the potential home buyers have to take a risk to make the twins' vision come true, and it's up to Jonathan and Drew to convince the couples that purchasing an older home in need of work is the best option.

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.

Seizing on the popularity of "Flip or Flop," starring Tarek and Christina El Moussa buying, renovating and then selling houses in Southern California, HGTV expands the franchise to include new duos in cities across the U.S. The first offshoot is set in Las Vegas, where Bristol Marunde and his wife, Aubrey, take on one of the country's most expensive, competitive, and unpredictable housing markets. After buying dilapidated properties via auction sales and real estate sites, the couple do most of the construction work themselves to keep their margins high. Aubrey is the designer and real estate agent; Bristol is the general contractor -- and his background as a mixed martial artist comes in handy during demolition. Together, they showcase their skills to complete stunning showpieces worthy of their top dollar zip code.

HGTV's "Flip or Flop" franchise moves to the Lone Star State, where military veterans Andy and Ashley Williams purchase rundown properties in and around Fort Worth and transform them into modern family homes.

Episodes also highlight the couple's commitment to hiring fellow veterans to assist on the projects. Andy and Ashley met while serving in the United States Armed Forces in Iraq.
