About This Home

As of October 2025

***Offers due on Friday, September 19, at 10:00 a.m.*** Ultimate privacy in every direction, as 7 acres of surprisingly low-maintenance landscaping provide seclusion and inspiring nature views. Situated on a knoll graced with huge oak trees, this home’s only owner was a prominent local builder. Featuring nearly 10,000 SF of custom living space, it’s comfortable for everyday living but designed for entertaining on a grand scale in the wide-open foyer, living and family rooms with wet bar. On the entry level, the primary suite consists of a huge bedroom, adjoining office/gym, and an en-suite bath with spa tub and shower, and dual sinks, water closets and walk-in closets. Also on the main level are the dining room which easily seats 12, the kitchen and breakfast nook, both with treehouse views and nearby access to the 4-car garage. Light-filled with picture windows, this home sets up perfectly for multi-generational living, with a studio under the garage, and the mid-level bedroom both with direct exterior access. Lower-level bedrooms are en-suite, and everyone will enjoy the recreation room, which has a wet bar and room for gaming. The adjacent full bath, which also has a sauna and steam shower, serves the huge stone deck patio, swimming pool and spa, and grass play area.
