A sense of balance and proportion defines this thoughtfully renovated residence, where carefully considered updates have refined the home’s original design. A wood entry door opens to a light-filled foyer, where expansive windows and long sightlines extend through the interior to the landscape beyond. Straight ahead, French doors lead to the terrace, establishing a natural connection between indoor and outdoor spaces. The main level is arranged with both clarity and purpose. To the left, a formal living room with fireplace opens to a private office enclosed by double French doors and detailed with custom floor-to-ceiling built-ins. To the right, the dining room connects to a well-appointed butler’s pantry with wine refrigeration and an integrated ice maker, providing a practical transition into the kitchen. The kitchen has been extensively updated and serves as the central gathering space. A marble island anchors the room, complemented by a Thermador six-burner range with griddle, double ovens, and a built-in Sub-Zero refrigerator. A window-lined breakfast area overlooks the grounds and opens directly to the patio. Just beyond, a step-down family room with fireplace and custom shelving offers a comfortable setting for daily living. Additional spaces on the main level include a walk-in pantry, secondary office, mudroom with generous storage, powder room, and access to the three-car garage. The lower level has been fully reworked to support both recreation and wellness. A custom bar with dual wine coolers, Viking appliances, a large island, and stone backsplash anchors the space. A recreation area, mirrored gym, and a private theater with sound insulation complete this level. Upstairs, the layout includes multiple bedroom suites, including a guest suite accessed via a secondary staircase. Additional bedrooms offer walk-in closets and well-finished baths, along with a spacious laundry room and dedicated storage and hobby areas. The primary suite reflects a more recent renovation, with a custom closet and a seating area set within a windowed alcove. The marble bath includes radiant heated floors, dual vanities, a soaking tub, and a glass-enclosed shower. Outdoor spaces are designed for ease of use, with a terrace overlooking landscaped grounds and a gated pool and spa with a cascading water feature. A home that reflects a thoughtful evolution over time—where meaningful updates have enhanced both function and comfort, and where each space connects with a quiet sense of continuity. Designed to support both daily routines and more relaxed gatherings, it offers a setting that feels considered, enduring, and easy to live in.
