Better than new construction, this exceptional custom home delivers sophisticated design, incredible indoor-outdoor living, and a spectacular backyard created for entertaining. A heated saltwater pool, bluestone patio, remarkable four-season room, and finished living space above the detached garage set this home apart, while four beautifully finished levels offer a thoughtful combination of luxury, functionality, and style. The heart of the home is a stunning O’Brien Harris kitchen featuring custom cabinetry, an oversized island, premium Wolf and integrated Sub-Zero appliances, and an adjoining scullery complete with prep sink, warming drawers, extensive cabinetry, and additional workspace-ideal for effortless entertaining. The open-concept kitchen flows seamlessly into the spacious dining area and inviting family room, where a gas fireplace, wide-plank hardwood floors, and abundant natural light create an elegant yet comfortable gathering space. Designed to make the most of every season, the exceptional four-season room features heated floors and dramatic accordion doors that open completely to the bluestone patio, creating a true extension of the home’s living and entertaining space. Beyond, the private backyard retreat centers around a heated saltwater pool with automatic cover, surrounded by mature privacy hedges and generous space for gathering, dining, and relaxing. A conveniently located powder room with dual access from the mudroom and four-season room is perfectly positioned for both everyday living and poolside entertaining. The second-floor primary suite is a serene retreat with vaulted ceilings, a private deck overlooking the backyard, custom walk-in dressing room with built-in makeup vanity, and spa-inspired bath featuring dual vanities, a soaking tub, and oversized walk-in shower. Two additional bedrooms, a dual-access hall bath, and a well-appointed laundry room complete this level.

The finished lower level provides even more space to unwind and entertain, with generous recreation areas, a custom wet bar with wine refrigerator, full bath, fitness area with a full-spectrum infrared sauna. Adding remarkable versatility is the finished space above the detached two-car garage. Skylights and a dedicated mini-split heating and cooling system create an ideal private office, studio, or flexible bonus space separate from the main residence. Additional highlights include Lutron lighting throughout, a thoughtfully designed mudroom, two 200-amp electrical panels, dual tankless boiler system, whole-house reverse osmosis water filtration system, water softener, humidifier, radon mitigation system, and dual sump pumps with battery backup.
