Six Cromwell Lane is a stunning fusion of classic and modern design, set on over six private, lush acres along a bucolic country lane. A tree-lined drive leads to the double-door entry and an understated, elegant foyer with views stretching to the backyard terrace, setting the tone for refined living. Flanking the entrance, the refreshed dining and living rooms impress with voluminous ceilings, expansive windows, and a cozy fireplace. The great room, with multiple French doors opening to the landscaped grounds, a handsome entertainment bar, fireplace, and coffered ceiling flows seamlessly into the oversized gourmet kitchen, where a wall of windows, turreted skylights, and generous gathering space create an inviting hub for cooking and conversation. A refined wood-paneled library with built-in bookcases opens to a glass-enclosed sunroom for quiet luxury. The serene first-floor primary suite features a fireplace, abundant natural light, a spa bath with steam shower and soaking tub, and a private hall connecting to a gallery-style dressing room and custom walk-in closet. Two formal powder rooms, a laundry suite, and an expansive mudroom with a secondary entrance from the four-car garage complete the level. Upstairs, three well-appointed ensuite bedrooms offer spacious sleeping and lounge areas, spa-worthy baths, and custom closets, while a front-to-back bonus room serves as a gym, media room, or second family room. Outdoors, the property engages all the senses with a cascading waterfall flowing into a koi pond beside the home's glass walls, stone footpaths for quiet reflection, a bluestone patio, and pristine tiered lawns. Mendham's highly rated schools, including the International Baccalaureate program, along with abundant parks and proximity to vibrant Morristown with shops, dining, and NYC transit, further enhance this magnificent property.
