For the very first time, Glen Kernan's iconic ''Castle House'' is opening its doors, offering a rare opportunity to own one of Jacksonville's most exclusive and private estates. This Mediterranean masterpiece sits on an expansive golf-to-lake homesite and delivers unmatched architecture, craftsmanship, and character. A grand circular drive leads to the signature turret tower, both dramatic and timeless. Inside, sweeping ceilings, custom ironwork, intricate stone detailing, and a breathtaking spiral staircase create elegance at every turn. The brilliant floorplan offers formal and casual living spaces, a showpiece library, an entertainer's chef's kitchen with hidden prep kitchen and butler's pantry, and a dedicated primary wing with private balcony overlooking the course, sitting room with wet bar, wood-burning fireplace, and a luxury-inspired spa retreat.... The home's resort-style outdoor living is equally extraordinary. Through a series of French doors, the interior flows seamlessly to an expansive poolside portico complete with outdoor fireplace, dining space, and panoramic views of Glen Kernan's championship golf course and tranquil lake. Every sunset becomes a private showpiece. Additional highlights include elegant guest suites, an elevator, hand-crafted woodwork and stone features throughout, and a level of architectural detail that has made this property truly one of a kind. Set within one of Jacksonville's most exclusive country club communities, offering golf, tennis, swim, fitness, and dining, this estate presents an unmatched opportunity to own a true piece of Glen Kernan history. Iconic, unforgettable, and available for the very first time.
