Architecturally significant mid-century modern designed by Harvard architect Carl Koch who studied under Gropius and Breuer. Stunning custom and rare example of Koch’s TechBuilt homes set on wooded lot with its own spring and waterfall, only ten minutes from Yale in the heart of Spring Glen. Large windows throughout bring the outdoors in with beautiful views. The dramatic upstairs living/dining room with high ceilings and walls of glass is partially cantilevered toward the spring creating a treehouse effect. Illuminated trees in the evening and the sound of the spring bring you to the middle of the woods. The four-to-five bedroom bi-level house has been carefully preserved with many original details intact including original hanging globe pendant lights, period appropriate cork floors throughout, and original well maintained kitchen cabinets. Other renovations include an imported tile bathroom with an extra large curbless shower. On the first level, with its own additional entrance, is the generous sized family room with a wall of glass abutting the spring, and two bedrooms, a bath and efficient home office. On the second level is the living/dining room, master bedroom with tall ceilings, another light-filled bedroom/home office, the open floorplan kitchen/great room with a beautiful exposed fireplace, and a wall of glass to the backyard. This is a one-of-a-kind home. Minutes to Yale, downtown New Haven, Hamden center.
