The kitchen introduces a contemporary counterpoint with sleek European-style cabinetry, granite countertops, and a full suite of high-end stainless steel appliances. It flows naturally into a bright breakfast nook, and a powder room completes the main level. Upstairs, the expansive primary suite serves as a private sanctuary, with two walk-in closets and a light-filled dressing room with a dedicated makeup vanity. The en-suite bath is elegantly appointed with dual vanities and a skylit shower-tub combination.

The lower level is designed for both relaxation and entertaining, centered around a generous recreation room with concealed storage. A bonus room, powder room, and laundry area complete the space. Outdoors, the parklike grounds provide a private and inviting environment, enhanced by the scale of the double lot. A freeform swimming pool is surrounded by flagstone hardscaping, creating a natural focal point for outdoor living. The charming bi-level pool house, finished in a lodge-inspired style with rich wood paneling, stacked stone, and slate tile, offers additional living and entertaining space, including a full bath on the upper level. Throughout the property, curated gardens, tucked-away seating areas, and a pergola contribute to a quiet sense of seclusion.
