Impeccable construction, a gracious layout, and idyllic landscaping – inspired by stately English country homes – are all on display in this distinguished 6,000 sf 5-BR beauty. Designed in 1915 by world-renowned American architect Wilson Eyre in the Queen Anne Revival Style, this spectacular home is nestled in Irvington’s esteemed Ardsley Park, a mere 40-minute train away from GCT. A graceful circular gravel drive enters the peaceful, 1.7-acre parklike property where one can delight in a vast level yard, stone terraces, and a range of bucolic sites for lounging (full of potential for future pool area). Some of the home’s distinctive features include a handsome brick facade, towering bay window, authentic slate tiles (1” thick at the eaves), and four unique working fireplaces! Enter through a majestic arched front door to find original wood-paneled walls and decorative ceiling beams in a towering stair hall, where the impressive triple-height bay windows flood the space in southern light. From there, all main-level rooms reveal the beauty of the home’s exquisite rear lawn, with its backdrop of flowering trees and picturesque rose garden wall. An expansive living room, bathed in natural light, flows into a wondrous sunroom where sweeping oversized arched windows frame stunning backyard views in 3 directions. A warm and inviting dining room offers an original wood-fired fireplace, sumptuous oak wall-panels, and French doors to a generous backyard stone entertainment terrace. Wood sliding doors reveal a magnificent oak-paneled library with fireplace and views to soaring trees at the property’s edge. Renovated in 2024, a modern, sun-filled chef’s kitchen includes top-of-the-line stainless appliances, white marble counters, and a spacious 6-seater island – just perfect for company while prepping. A separate butler’s pantry and cheerful breakfast room sit beyond. Upstairs, enjoy a private primary suite: luxurious bedroom, two discreet dressing rooms with backyard vistas, luminous bath, and adjoining sitting room/home office. Three additional bedrooms and two baths are found on this level, with a dedicated guest bedroom and bath beyond. Below, a huge walk-out basement with 9’-high ceilings provides even more: family room with brick-arch fireplace and bar, exercise room, laundry room, bath and sauna. The home’s walk-up third level attic and detached 2-car garage offer even more storage. With easy access to two equidistant Rivertown villages, the beloved Aqueduct Trail, picturesque Halsey Pond, Ardsley-on-Hudson train station and award-winning schools, the pastoral elegance of this exceptional gem of a home is truly one-of-a kind!
