The best is that the purchase of this building comes with a bonus of over 3,700 square feet, including a 1,000-square-foot permitted ADU. The oversized 7-car garage and large living room could even be used as a clubhouse. This timeless 5,306-square-foot residence, nestled in the prestigious Country Estates community, blends historic charm with refined luxury. Originally a grand library, the residence retains its architectural splendor, with soaring ceilings and expansive windows bathing the interior in natural light while offering sweeping views of the surrounding landscape. This is the only hilltop property in the Country Estates community where both buildings are situated on flat land.
Situated on nearly 1.5 acres, the property offers ample space, privacy, and a resort-style lifestyle. The main house boasts 5 bedrooms and 4.5 bathrooms, with a thoughtfully designed layout, including a first-floor master suite, perfect for entertaining family, friends, or guests. A chef's kitchen with a separate prep kitchen is perfect for entertaining, while a private wine cellar enhances the residence's refined charm.
Outdoors, a beautiful pool provides the perfect spot for relaxation and gatherings under the open sky.
This extraordinary estate, boasting iconic architecture, modern amenities, and spaces for living, working, and entertaining, is a rare find in one of the area's most sought-after communities.
