Day light floods into almost every corner of the very open floor plan. The clean lines of a rectangular box set off the beauty of carefully selected materials such as handsome hardwoods, brick and bluestone to create a warm and unique space punctuated by large windows, walls of glass and simple built-ins. Sitting high above the Stoney Brook on a sloping, terraced lot with views of nature and glimpses of a favorite Princeton neighborhood. The indoor/outdoor relationship that was a hallmark of its design was further enhanced by patios, breezeways, and the way that additions to the original house were connected. The entrance from the street is discreet with the excitement of this house unfolding dramatically once inside the front door. This is Marcel Breuer's Levy House with its earliest section dating to 1953. Known to scholars and followers of Mid-Century Modern houses, this fully evolved Breuer residence has two additions by the master architect and brings to life the very premise of good, affordable design that could be adapted and expanded with the needs of the owners. Furthermore, since it has been in the same family since construction, Breuer's principles have been upheld and cherished making it perhaps the purest surviving example of Breuer's residential work. Highlights include windows surrounded by polished hardwoods, glowing wood floors, built-in bookcases and accent windows. Perhaps most striking are the stairs made of thick wood planks and Breuer's signature metal stair rail. Or maybe it is the original paint colors on accent walls and ceilings. Then again it could be the lower level bedroom that has a built-in Japanese style soaking tub. It is the scale that makes the spaces comfortable, welcoming and familiar. The entrance level has Breuer's bold use of color along a corridor that leads to a serene family room with two full walls of glass, the understated elegance of a simple, two sided fireplace and wall of built in shelving. Beyond is the last addition to the house which features a bedroom with a sunken tub situated in front of another wall of glass looking out onto a private garden. The stairs to the second floor lead to the middle of the large open living room/dining room making one's arrival the center of attention. A wall of glass has openings to a large area poised for outdoor cooking, entertaining or relaxing. The second addition to the house was achieved by creating a floating breezeway connector.
