Dubbed the “Nautilus House” for its shape, this Ann Arbor home received certification as Michigan’s second U.S. Green Building Council LEED Platinum-level whole-house remodel. The client, a found-object artist and metal worker, “wanted this house to be a harbinger of innovative green design and construction,” architect Michael Klement says.

Without increasing the home’s footprint, Klement radically changed this typical suburban colonial into a visually arresting and environmentally sensitive residence where beauty meets functionality. “This is a dream house for a lot of people,” the judges said. “It’s sheer innovation and rule-breaking.”

The project uses state-of-the art building envelope techniques including cellulose insulation, engineered-wood products, spray polyurethane foam, and structural insulated panels (SIPs) to minimize energy loss. A photovoltaic roof array allows the home to make more energy than it uses during the summer. The standing-seam metal roof, which lasts longer than a standard roof, delivers clean water to rain-saving catchment containers, which can be used for the outdoor shower. Inside, flexible design strategies and an open floor plan make the 3,220 square feet of living space seem larger.
