This one-of-a-kind, award-winning residence is truly a work of art. Designed by the renowned UKZ Architects, this architectural masterpiece introduced Modernism to North Caldwell and remains a landmark of timeless sophistication just 19 miles from New York City. The first floor features soaring 10 to 12-foot ceilings and is bathed in natural light, thanks to dramatic floor-to-ceiling window walls and expansive windows that invite the outdoors in. The seamless connection to nature continues in the beautifully landscaped garden, adorned with a romantic wisteria vine, and the impressive 34' x 23' Entertaining Terrace perfect for hosting under the open sky. Meticulously renovated in 2023, the home is now the epitome of Super Chic 21st-century living. The designer kitchen boasts top-tier appliances, including a Wolf stove, oven, and microwave, a Miele dishwasher, and a Sub-Zero refrigerator. The spacious primary suite is a private retreat, featuring a cathedral ceiling and a stunning, newly designed 22-foot-long spa-like bath. Throughout the second floor and family room, exquisite new custom herringbone hardwood floors enhance the luxurious feel. Additional features include a strikingly updated powder room, a wine room, a cedar wardrobe closet, and an oversized two-car garage accessed via a private motor court. Conveniently located near shopping, dining, libraries, Montclair, and public transit to NYC, this home combines high design with everyday ease.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
