Maine and an Underwater Basement

Mark Evans follows British-born Steve King and his friend Rick Keith, who meet up in Maine, New England, every year to restore old boats. Now Steve wants to make his own tiny floating home - and, by using recycled materials, he plans to spend no more than ú7000 on it. There's also Michelle Lanker and Bill Bloxom - outdoor-loving environmentalists who want to make a floating home with a breathtaking design: the curved roof of their boat will be covered in grass and solar panels. They also plan a huge underwater basement, with a window looking out into the fishy waters below. But making the window thick enough to withstand the elements proves a real struggle.
