Transforming a home's 20-year-old wooden deck with views of Pikes Peak, Colorado, into a $400,000 mega deck requires a complete demo and rebuild, complete with 13-foot-tall stone wood-burning fireplace, sliding glass panels to enclose the living area, gas fire pit, two dining areas and a grill station complete with granite countertops and a kegerator. Plans also include redoing a kids' play deck and a master bedroom deck. The challenge is that the property sits on the side of a cliff, with 40-foot drops off the deck level and no access from the postage stamp-sized backyard. Master builder James resorts to innovative building methods to get the job done, all while battling 60-mph wind gusts, blinding fog and death-defying heights.
