Shirley and Russ want to join a community of 600 floating homes in Canada. They're set on a luxury ranch-style floating home with wraparound decks, but the launch is hair-raising - one slip and it will be a disaster. Also, Glenn and Margaret build a nautically themed floating home with a high barrel ceiling in a marina on Vancouver's north shore.

Susan Dunn is passionate about building a stunning floating home using the latest in contemporary design in Seattle, Washington. And Harry Janzen and Tina McComb dream of a massive three-storey wilderness retreat.
