Finnish designers Aleksi Hautamäki and Milla Selkimaki have done what many only dream of — they have bought an entire island to construct a gorgeous off-grid retreat. Located on 5 acres of rugged landscape, at the edge of the Archipelago National Park in Southwest Finland, Project Ö includes two self-sustaining, solar-powered cabins that include chic living spaces as well as a sauna and a workshop. The ambitious designers purchased the remote island two years ago with plans to built a set of off-grid cabins.
