Gazing from a cramped deck is no way to take in gorgeous mountain views, so the Mega Team has big plans to knock it down and create a larger, enclosed space that the homeowners can enjoy throughout the year. But as the crew uncovers a retaining wall below, the plans for expansion come into question. They also battle cold temperatures, icy terrain and hoisting a 500-pound door over the edge of a 25-foot cliff. In the end, the custom fire rail, full glass enclosure, skylight, custom kitchen and private master suite deck make it worth all the effort.
