John and Bonnie have a very large family and a very small deck. And with their six adult children living nearby, they really want a place for the family to gather. So, they've decided to turn their old deck into the ultimate party deck. The Mega Crew is challenged to build a $300,000 deck that takes advantage of the gorgeous views and adds 1700 square feet of outdoor living space. The plans call for a comfortable living room with gas fireplace, a state-of-the-art outdoor kitchen, sliding glass walls, a dining area and a fire pit. The four-season living space will also feature some of the best ideas when it comes to improving outdoor privacy.
