Located on the premises of Camp Wandawega in Elkhorn, Wisconsin (a 1920s lakeside resort revitalized by husband/wife team David Hernandez and Tereasa Surratt), the just-completed Wandawega Tree House is now available for vacation rentals. The couple enlisted a group of friends (furniture makers, artisans, and builders) to collaborate on the three-level structure, which features reclaimed wood, vintage windows, and interior touches like pillows made from flour sacks and out-of-print books on Wisconsin history. Go to Camp Wandawega for more information; to read more about the tree house, go to Chicago Home + Garden.
