9515 Harbor Lights Dr. is more than a home - it is a lifestyle, a legacy, and an aspiration brought to life. Positioned in one of the most desirable waterfront settings in West Ocean City, this masterfully designed, custom-built waterfront residence sits on over 1.39 acres at the end of a private cul-de-sac, delivering estate-level privacy and an elevated coastal lifestyle within the Ocean Reef community. The setting offers panoramic views of the bay, the unspoiled natural beauty of Assateague Island - renowned for its protected shoreline, wild horses, and untouched coastal landscape - the Ocean City Inlet, and the iconic skyline of the world-famous Boardwalk, complete with the Ferris wheel and roller coaster. From the moment you step inside, the intention of design is immediately felt. A custom front door featuring circular glass detailing sets the tone, with this signature motif thoughtfully repeated in complementary architectural elements throughout the home. An elegant foyer with designer lighting opens to a dramatic great room, where walls of glass flood the space with natural light and frame sweeping water views. The kitchen is a true chef's playground, anchored by an oversized island, professional-grade appliances, custom cabinetry, and bayfront dining - designed for both elevated entertaining and everyday enjoyment. The open-concept layout ensures seamless flow between living, dining, and entertaining spaces, all oriented to maximize the home's breathtaking waterfront setting. This custom coastal residence offers 5 bedrooms, 3 full bathrooms, and 1 guest bathroom, along with a den/office/media room that could even function as a 6th bedroom, thoughtfully designed to balance luxury and livability. The owner's suite is a private sanctuary, generously scaled and appointed with a sitting area, wet bar, and gas fireplace set into a striking statement wall. A private balcony captures expansive bay views, while the spa-level bath and walk-in closets complete the retreat-like experience. A separate staircase leads to a beautifully appointed guest suite, a design choice focused on maximizing privacy, autonomy, and comfort - ideal for long-term guests, in-laws, or live-in staff. This suite features a combined living room and office space, sauna, bayfront bedroom, and en suite accommodations, offering a true secondary residence within the home. Outdoor living is elevated to a resort-caliber experience, with multiple levels of maintenance-free Trex decking creating distinct dining and lounge areas, complemented by a built-in grill and bar island with flexible seating, fire pit lounge, and tranquil fountain - perfect for entertaining against the backdrop of the bay. Completing the property is a collector's three-car garage with finished flooring and a built-in workstation, offering both functionality and refinement. Every element of this home reflects intentional design, curated craftsmanship, and a commitment to coastal luxury living at its highest level.
