This home evokes a sensuous St. Barth lifestyle on Lake Michigan, designed for globetrotting clients who wanted a weekend sanctuary near their primary residence in Chicago. The project brief included open plan living for entertaining, a family lounge, and bedroom suites for houseguests. The first level is a glass rectangular volume that makes the second level appear to float over the dune and offers water views through the structure. Clad in Accoya, the upper level will gray with age and blend into the landscape. These two horizontal volumes are connected by a double-height glass entry space that reveals a floating staircase. A contemporary beach aesthetic unifies the interior through an edited palette of materials, including white oak millwork, large-format porcelain tile, and a range of warm whites. Interior tile extends out to the pool terrace, uniting the spaces and amplifying the connection to the outdoors. The landscape design enhances the experience. A courtyard with sculptural Ginkgo trees offers refuge from lake breezes. On the pool terrace, custom Cor-Ten planters overflow with Russian Sage, selected for graceful foliage that sways in the breeze and offers a relaxing herbal aroma.
