A rare architectural statement set amid serene privacy and expansive grounds, this extraordinary residence by UKZ Architects introduced Modernism to North Caldwell just 19 miles from New York City. Celebrated and award-winning, the home is conceived as a livable work of art, defined by two intersecting L-shaped planes that frame the landscape and dissolve the boundary between indoors and out. The architecture invites nature into the experience of daily living, with a sculptural garden wall draped in wisteria that guides the eye from exterior to interior. Clean lines, intentional sightlines, and a seamless connection to the surrounding land create an atmosphere of quiet sophistication and retreat.The renovated kitchen is a study in modern functionality, featuring a Wolf range, oven, and microwave, Miele dishwasher, and Sub-Zero refrigerator perfectly suited for both everyday living and elevated entertaining. The private primary suite offers a tranquil escape, complete with a redesigned spa-inspired bath.Tucked away yet effortlessly connected to Montclair's dining, culture, and NYC train and bus service, this home offers the rare opportunity to live immersed in modern design, privacy, and nature where architecture, art, and lifestyle converge.
