A Designer Builds a Scandinavian-Inspired Sauna That Floats Off the Maine Coast

Brendan Ravenhill likes to describe his summers in Maine as half vacation, half working meditation. Most of the year, he’s in Los Angeles, where his design studio is primarily known for lighting fixtures. But when he returns to his family’s homestead on Little Cranberry Island, a short boat ride southeast of Acadia National Park, he tends to personal projects: building wooden boats, a pondside tea house, and, over the course of three months last year, a floating sauna.
