In 1957, Alcoa Care-free homes designed a 1900 square foot home constructed completely of plate glass, framed by aluminum and supported by posts that were clad in aluminum. Today, only a few of these Alcoa homes remain in anywhere near their original form. Whitney and Robert McChane didn't mean to buy a piece of history, but now that they did, they're intent on keeping it as close to original as possible. With the help of Host Amy Matthews and a savvy real estate agent, they'll help the McChanes make the right restoration choices so they get the biggest bang for their 20k budget.
