Situated on 2.3 acres with almost 300 feet of ocean frontage, this restored and expanded modern stucco Norman Jaffe design features a stone, steel, and concrete structure. With seven bedrooms, seven bathrooms, an elevated dining area, stone patios, a heated spa pool, and tennis court, this Hamptons retreat is the ideal spot for family gatherings and large social functions, not to mention a little down time to meander along the dunes.
