Perched along distinguished Upper Mountain Avenue -- where the town meets the mountain. This 3 Bed/1 Bath/2 Powder Room Colonial offers the rare pairing of Montclair's desirable uptown setting with a true backyard retreat. Inside, a panoramic glass Living Room fills the home with natural light, while the Chef's Kitchen w/ appliance garage and eat-in space at a bay window anchors everyday living. A large Office/Library, an expansive Mudroom, and a finished Basement, all add exceptional practicality. Upstairs, the Primary Bedroom and 2nd Bedroom host king size beds, while the Primary Bedroom and 3rd Bedroom each have attached Bonus Rooms. See Floor Plans. Situated into the mountainside, the property offers a quiet seclusion uniquely found in Montclair. A mature perennial garden surprises with new color and texture throughout the seasons. An architecturally significant fieldstone terrace and mountain-view backdrop feels private and elevated. Extensive exterior lighting and hot tub. Two train stations seven minutes away. Ideally positioned near Upper Montclair Village and the natural beauty of Mills Reservation, the home is moments from Presby Iris Gardens, the town pool, public tennis courts, soccer fields, and the beloved sledding hill. A stand out property among this Spring Market.
