Exceptional Hudson Valley Estate, Where Modern Living Meets Mountain Majesty. The uniqueness of this impressive property begins with its siting. Nineteen acres at the base of Mount Washington, flanked by Taconic State Park to the east and the Harlem Valley Rail Trail to the west, deliver sunrise over the Taconic Range and spectacular sunsets over the Catskills, with open Hudson Valley views. Opportunities for biking, hiking, snowshoeing, skiing, and kayaking abound, surrounded by regular sightings of blue herons, bald eagles, hawks, cardinals, and hummingbirds. This architecturally refined 5,540 sf home offers 5 bedrooms, 2 offices, two five-fixture bathrooms, one three-fixture bathroom, and a powder room--made for entertaining indoors and out, yet equally comfortable for two. The entire interior was redesigned and renovated beginning in 2020. At the heart of the home is a state-of-the-art kitchen featuring a Sub-Zero 36'' refrigerator/freezer, Wolf 6-burner range with griddle and dual ovens, Wolf stainless hood, Miele dishwasher, dual sinks with disposals, quartzite countertops, custom Italian cabinetry, two appliance garages, and a 10' entertaining island. Just steps away, a 50' lap pool and 8'×8' hot tub anchor the outdoor living area. The L-shaped layout of the house allows required pool fencing to run contiguous with the structure, naturally creating a more informal, secured southern end--with pool and garden--and a formal northern end with living and dining rooms. The living room features a soaring vaulted ceiling and an enormous bay window that puts the Catskill view center stage, anchored by a carved limestone fireplace. The expansive primary suite is a private retreat with a gas fireplace, smart bidet toilet, double sinks, soaking tub, and luxurious rain-and-waterfall shower. Four guest bedrooms, two home offices (one perched high atop the house), formal and informal dining rooms, a mudroom, large gym, and two laundry rooms provide both practicality and flexibility for remote work or multigenerational living. The three-car radiant-heated garage is a dream for collectors and hobbyists, with a new polyaspartic floor, granite-topped workstation with sink, and 240V EV outlet. Long-term peace of mind is supported by a whole-house generator, new roof (2024), and Buderus heating oil boiler. Fresh well water is centrally filtered and conditioned, and a residential elevator connects all three levels. Five-zone radiant heat runs throughout the floors--complemented by central air conditioning and blown hydronic heat for year-round efficiency. Additional highlights include two monitored alarm systems, a smart water monitoring system with automatic shut-off, and a private fiber optic internet line.
