This boutique hotel on Norway's Manshausen Island is made up of four sea cabins—one of which juts out from a natural ledge. Each of them fit two to four travelers or a family of five.
Architect Michael Cobb used Douglas fir harvested from the site throughout the house, such as on a sliding door outfitted with Swiss Rod SS hardware from the Real Carriage Door Company.
For the walls surrounding the living room fireplace, Cobb specified high-volume fly ash concrete made with a by-product of burning coal in power plants that usually ends up in landfills.
