Diamond Heir's Oceanfront Bridgehampton Estate Asks $45M

A Bridgehampton oceanfront designed as a gallery-like retreat for art collector Ara Arslanian hits the market on Dune Road.

Published on Mar. 6, 2026

The $45 million oceanfront estate at 15 Dune Road in Bridgehampton was originally built by the late Ara Arslanian, a prominent figure in the international diamond trade and a serious collector and patron in the 1980s New York art world. The home was designed with UV-protected Arcadia glass walls and top-tier glazing to safeguard Arslanian's art collection from coastal exposure.

Why it matters

It features a three-story glass elevator, an open-concept living, dining and kitchen area, a gym, a media room, and a rooftop deck with 360-degree views. The property also has direct access to Mecox Beach.
