Overview: In this special episode of George Clarke's Amazing Spaces, George and master-craftsman Will Hardie explore the ingenious small-space wonders hidden away among the snowy peaks of the Swiss, French and Italian Alps. Starting an epic road trip from an observation point 4000m above sea level, they set out on an adventure spanning mountain ranges, which takes in a secret ski lodge disguised as a boulder; a tree house resembling a giant acorn; a traditional Swiss cabin made almost entirely from concrete; and a tiny hamlet made up of eight 200-year-old chalets brought together from all over the Alps. And before heading home, George and Will visit a breathtaking mountaintop restaurant resembling a spaceship, before competing in a toboggan race.
