About This Home

89-91 Mosle Rd

Set behind a gated entrance on 10 private acres in the Somerset Hills, 89–91 Mosle Road is a rare two-residence estate compound totaling approximately 15,000 sqft. With a substantial main residence, an independent second residence, resort-caliber outdoor amenities, and sweeping views across the full property, the estate offers a level of privacy, scale, and multi-structure living that is rarely available in one offering. The main residence at 91 Mosle Road offers approximately 10,000 sqft, with 7 bedrooms and 8.2 baths. Positioned high on the property, the home is oriented toward broad views over the pool, lawns, second residence, and surrounding acreage. Its scale and setting create a distinctive estate experience: the grandeur is delivered from within the home and across the landscape, with the main house visually commanding the full property. Inside, a two-story foyer with herringbone floors opens to elegant formal living and dining rooms, a cherry-paneled office, and a dramatic sunken great room with coffered ceiling and fieldstone fireplace. The newly reimagined 2024 Arclinea chef’s kitchen is a major centerpiece, featuring Wolf, Sub-Zero, and Cove appliances, an oversized island with integrated dining, built-in breakfast / coffee bar, and separate prep kitchen with large pantry. The recently renovated private primary wing includes a fireplace, multiple walk-in closets, and a spa-style bath with heated floors and Porcelanosa fixtures. Complementing the private primary wing, the main residence includes six additional bedrooms, each paired with a newly renovated, high-quality bathroom finished with thoughtful materials and a refined aesthetic. One bedroom is located on the first floor, offering convenient accommodations for guests or extended-stay needs, while the remaining bedrooms are arranged on the second level, providing beautifully updated private spaces for family and visitors. The walk-out lower level expands the lifestyle offering with a pub-style bar and billiards room, wine cellar, media / recreation space with projector, gym, and abundant storage. The second residence at 89 Mosle Road offers approximately 5,500 sqft, with 3 bedrooms and 4.1 baths, creating a true independent living environment rather than a conventional guest house. Designed with modern farmhouse character, it features 12-foot ceilings, a cathedral living room with barnwood beams, a two-story double-sided fieldstone fireplace, and walls of windows overlooking the estate. The residence includes a designer kitchen with marble counters and Bertazzoni range, first-floor primary suite, upper-level loft and en-suite bedrooms, including a second primary bedroom, full oversized professional level gym, and dedicated altitude-training room. The grounds are designed for resort-style use, with expansive bluestone patios, heated pool and spa, fully equipped pool house, gated drive, broad lawns, and exceptional privacy. With two substantial residences across approximately 15,000 total sq ft, a rare 10 acre setting, and a main house overlooking the full property, 89–91 Mosle Road offers a distinctive compound lifestyle in the heart of the Somerset Hills.
