Property Description
Hidden among 5.5 private wooded acres, this one-of-a-kind mid-century modern home, designed by architect Gordon Kovell, was thoughtfully built into the hillside to embrace its natural surroundings. Designed to bring the outdoors in, soaring brick walls, dramatic skylights, warm wood ceilings and beam details, and walls of glass create the unforgettable feeling of living in an architectural treehouse. A spectacular skylit atrium welcomes you inside and serves as the heart of the home, featuring soaring exposed brick, an open staircase, and a unique indoor planting area that beautifully reflects its connection to nature. The living and dining areas showcase vaulted tongue-and-groove wood ceilings, hardwood floors, a striking fireplace, and expansive windows framing peaceful wooded views. The thoughtfully designed kitchen honors the home's architectural heritage with beautifully preserved custom wood cabinetry, quartz countertops that complement its timeless design, and an efficient layout. A private main-floor office with custom built-ins provides an inspiring workspace, while a three-quarter bath and laundry room complete the main level. Upstairs, four bedrooms continue the home's warm architectural character with vaulted wood ceilings and abundant natural light. A distinctive upper-level office with unique architectural windows and a charming loft creates an inspiring retreat for work or creativity. The primary bedroom and an additional bedroom open to a private upper-level balcony overlooking the surrounding woods, while the full bath is framed by dramatic windows that further reinforce the home's seamless connection to nature. Lovingly maintained and rich in authentic mid-century modern character, this exceptional home offers timeless architecture, exceptional craftsmanship, and a setting that simply cannot be replicated.
