Welcome to 46 Audubon Lane, a magnificent custom-built two-story estate nestled on a private, exceptionally quiet preserve homesite with zero road noise in Sugar Mill Plantation, Flagler Beach. Blending timeless architectural heritage with modern luxury, this home incorporates authentic elements repurposed from the historic 1916 Ponce de Leon Golf Course Clubhouse-including the striking original 10-foot geometric wood front doors, a magnificent marble-surround living room fireplace, and an exquisite historic chandelier gracing the soaring two-story family room.

Offering over 5,000 square feet of meticulously maintained living space across a versatile 5-bedroom plus office, 4 full-bath, and 2 half-bath layout, the home features an expansive open-plan interior enhanced by stunning travertine flooring throughout the downstairs, brand-new Hallmark LVP flooring upstairs, elegant crown molding, and custom built-ins in the oversized walk-in coat closet which functions as a second pantry. The gourmet kitchen is fully equipped with premium appliances-including a gas range, microwave/oven combo, refrigerator, and dishwasher-effortlessly connecting via impact glass sliding doors to the covered lanai featuring a motorized power screen and resort-style outdoor living spaces. Flexible spaces abound, including a formal dining room, a main-floor guest/in-law suite option, a dedicated front office/study with custom built-ins and frosted-glass double doors, a glass-enclosed wine room near the foyer, and a luxurious main-floor master retreat.

French doors open from the upper suite to an expansive stone-paver balcony with motorized awnings-offering a private vantage point for evening stargazing or watching live rocket launches, all while taking in panoramic preserve and pool views.
