New construction in 2026, this beautifully designed Colonial offers an exceptional blend of modern luxury and space for everyday living and entertaining. A welcoming two-story foyer introduces elegant millwork, hardwood floors, and a flowing main level where the expansive family room, complete with a fireplace and coffered ceiling, opens to a showstopping kitchen with an oversized waterfall island, premium appliances, and generous space for gathering. A dining area, bedroom with a full bath, and additional powder room complete the first floor. Upstairs, the spacious primary suite offers a private retreat with a custom walk-in closet and spa-inspired bath featuring a soaking tub and oversized shower. Three additional bedrooms offer comfortable accommodations, including two connected by a Jack-and-Jill bath and a third with its own private en-suite, complemented by the convenience of second-floor laundry. The finished walkout basement extends the living space with a large recreation area, den, bedroom, and full bath. Outside, enjoy a raised deck overlooking the expansive backyard, a lower-level patio, an attached garage, and a generous driveway. Conveniently located in Mountainside near Route 22, Echo Lake Park, Watchung Reservation, and shopping and dining in neighboring Westfield.
