Working with Mike Killeen in a fun, collaborative process, this Des Peres couple designed their dream home -- a single-story, prairie style house with horizontal lines, ample natural light, green features and modern touches. The 5400 ft² home includes a large clerestory skylight inspired by Frank Lloyd Wright's Robie House in Chicago. The skylight's exterior brick detail presented design challenges for the structural engineer, who designed steel i-beams to support the weight. The clerestory windows, tall ceilings, and transoms give the home a bright, airy feel. The main floor has a combined kitchen, living and dining area with built-in shelves and cabinets. A large custom fireplace and integrated entertainment system preside over the great room. The residence includes three bedrooms, two project rooms, and 3 garage spaces, including a Corvette bay. A wide open staircase leads to the finished basement used for entertaining. The house has two full- and two half-bathrooms, all with built-in sinks and wall-mounted European-style fixtures. The master bathroom includes a walk-in shower, his-and-her sinks, separate toilet room and custom make-up vanity.
