5499 Dune Drive elevates coastal living through striking modern architecture. Set within Avalon's legendary High Dunes, one of only eleven properties occupying the island's highest natural elevation, the residence pairs bold contemporary design with one of the rarest settings on the eastern seaboard. Designed by acclaimed architect Mark Asher and meticulously crafted by JG Popper, the residence embraces a distinctly modernistic aesthetic, with clean lines, soaring expanses of glass, and a carefully curated palette of natural materials shaping spaces that celebrate light, views, and the surrounding landscape. Every line serves a purpose. Every space is composed to capture the dynamic natural glow from sunrise over the Atlantic to sunsets across the back bays. The materials are as carefully considered as the design itself. Custom Arcadia aluminum window and door systems frame uninterrupted views from ocean to bay while dissolving the boundary between indoors and out. Shou Sugi Ban cypress, weathered Alaskan yellow cedar, premium Ipe hardwood, bluestone, walnut, and Caesarstone were selected not only for their warmth and texture, but for their natural beauty and resilience in the coastal environment. The result is a home that feels equally refined and enduring. That same commitment to thoughtful design extends beyond what is immediately visible. Advanced acoustic insulation, precision engineered building systems, whole home automation, and integrated lighting and shading work quietly in the background, creating a residence that is as effortless to live in as it is beautiful to experience. Life unfolds across four thoughtfully composed levels connected by an elevator. The dramatic main living level brings together the chef's kitchen, dining area, living spaces, and temperature-controlled wine room beneath soaring walls of glass that open to expansive terraces overlooking both ocean and bay. A private wellness level, pool and spa, and a full floor primary retreat complete a home designed equally for entertaining, restoration, and everyday living. In a setting defined by rarity, 5499 Dune Drive stands apart for something equally uncommon: a home conceived with an ambition befitting its extraordinary location.
