Description

Welcomed by a gated private drive and set on over 9 acres of pristine grounds, this iconic 1916 manor has been meticulously restored and strategically enhanced to meet the expectations of today's most discerning buyer. Historic architecture remains intact, while systems, technology, and modern amenities have been elevated to a truly exceptional standard.

The grand formal living and dining rooms feature museum-quality millwork and cabinetry, offering a refined setting for both intimate gatherings and grand entertaining. The gourmet kitchen is designed for serious cooking and seamless entertaining, flowing naturally into the home's primary living spaces. An impressive paneled library with a wood-burning fireplace provides a cozy and private retreat, while the stunning 21' x 40' living room, designed by Smiros & Smiros, commands attention with 16' ceilings and a dramatic stone fireplace – built for memorable entertaining.

The primary suite functions as a true private residence within the home, complete with a separate sitting room, a coffee bar and powder room, a spa-level marble bath with radiant heated floors, and two walk-in closets. Five additional bedroom suites, including a fully ADA-accessible suite, along with an office overlooking the gardens, complete the second floor.

Amenities rival those of a private resort, including a paneled elevator, an indoor infinity lap pool, a catering kitchen, a dog spa, a fully renovated gym, and a discreet panic room/safe with interior access, offering an elevated level of security.

For the car collector, the property offers rare flexibility: a heated three-car garage with high ceilings designed to accommodate lifts for up to six vehicles, complemented by two additional one-car garages.

The grounds are equally intentional. A new slate roof, heated gunite pool, Har-Tru tennis court with lighting (recently resurfaced and fenced), putting green, English gardens, playhouse, and curated exterior lighting create a private, park-like setting designed for year-round enjoyment. Extensive masonry restoration, irrigation repair, landscape clearing, and exterior updates have been executed on a grand scale.

Behind the scenes, the home has undergone substantial systems modernization, including new and revised HVAC systems, complete attic insulation, comprehensive electrical upgrades, restored fireplaces, enhanced pool infrastructure, a fully revised gate and telecommunications system, and corporate-level security with AI-enabled cameras and Wi-Fi coverage throughout the property. The interior has been fully renovated with freshly painted finishes, restored hardwood floors, custom window screens throughout, and exterior finishes replaced with durable Azek for longevity.

This is not simply a restored property – it is a fully realized modern compound where legacy architecture meets visionary execution.
