Built on a challenging hillside site and tucked behind a thicket of trees, the Bridgman, Michigan, house designed by Scott Rappe provides a modern weekend retreat for a Chicago couple. “One of my first responsibilities was getting the owners up to their house and essentially on one level. Because of the pie-shaped property, we needed to push the building up the hill to provide square footage for the program. By keeping the building perpendicular to the slope, using piloti on one side and a retaining wall on the dune side, we were able to insert foundations with minimal disturbance," says Rappe.
