The M-22 House by Michael Fitzhugh fits within Northern Michigan’s landscape while also taking advantage of renewable energy available on site. Modern design and decor are tempered with natural materials and lots of glazing to enjoy the beautiful natural setting on West Grand Traverse Bay, and geothermal heating and cooling works alongside a unique hydropower system to run the lakeside retreat.

M-22 House is located on a tall ridge overlooking Grand Traverse Bay with views that encourage discovery of the landscape. Inspired by the elements of fire, earth, wind and water, the home comprises a play on nature as well as a way to interact with it. Low maintenance materials like concrete, steel, and composite siding make up the exterior and carefully placed windows let in natural lighting.

Michael Fitzhugh Architect completed the M-22 House in October, 2013. It is partially built into the hillside to take advantage of the earth and hilltop views. The home also incorporates an innovative energy system composed of both geothermal and hydropower. A traditional geothermal system provides energy efficient heating, cooling and domestic hot water with the help of heat pumps and radiant floors. Meanwhile, a hydroelectric power generator uses rainwater, geothermal water and gravity to produce power. A schematic diagram at OneKindDesign gives an overview of the system, which is wired for future solar and wind generators.
