A newly listed oceanfront estate in Bridgehampton comes with both architectural pedigree and a backstory rooted in the art and diamond worlds of 1980s New York.
The trophy Hamptons property at 15 Dune Road, now asking $45 million, was built by the late Ara Arslanian, a second-generation diamond dealer known not only for rare stones but also for his close ties to artists including Jean-Michel Basquiat, Keith Haring, and Andy Warhol.
Arslanian spent nearly a decade planning the home, shaping it as both a private residence and a setting for his contemporary art collection.
That dual purpose is still visible throughout the property, where museum-level materials and carefully controlled natural light were integrated into a structure designed to face the ocean at every turn.
The estate is listed with Kyle Rosko, Keren Ringler, and John Gomes of Douglas Elliman.
Built along the shoreline so every room faces the water


Set on 1.91 acres, the 7,059-square-foot residence follows a linear layout that stretches along the shoreline rather than stacking views into a single façade.
This design allows every principal room to look directly out to the Atlantic Ocean, while the opposite side captures views of Mecox Bay. The result is a house that moves with the light — from sunrise over the ocean to sunset across the bay — without requiring a change in vantage point.
Balconies and terraces extend this experience across multiple levels.

Designed by Mark C. Matthews with interiors by Francis D’Haene
The standout home at 15 Dune Road at was designed by Mark C. Matthews Architecture in collaboration with Francis D’Haene of D’Apostrophe Design.
Inside, the materials and proportions are restrained but deliberate. Full-height sliding glass walls frame the surrounding landscape, while custom millwork and controlled color palettes keep the focus on the setting rather than decorative excess.

With rooms positioned to take in the ocean views
The main living, dining, and kitchen areas are arranged as a single continuous space oriented toward the water.


Arcadia glass walls installed to protect museum-grade art
One of the home’s more unusual features is its use of UV-protected Arcadia glass throughout.
The glazing was selected specifically to shield artwork from coastal exposure, reflecting Arslanian’s intent to display works by artists such as Basquiat, Haring, Warhol, Jeff Koons, and Julian Schnabel inside the home.

This level of consideration is rarely seen in oceanfront properties, where expansive glass is often prioritized without the same level of protection.
A three-story glass elevator keeps the ocean in view
A glass elevator connects all levels of the home, positioned so that ocean views remain visible throughout the ride.
It reinforces the home’s central idea: maintaining a continuous visual connection to the water, regardless of where you are in the house.

Living spaces open directly to a heated oceanfront pool
The main living areas open onto a heated gunite saltwater pool positioned on the ocean side of the property.
From here, the transition from interior to exterior is immediate, with lounge areas, terraces, and direct access to the beach just beyond.

The pool sits parallel to the shoreline, keeping the ocean as the dominant backdrop.
Seven bedrooms, multiple levels, and spaces for work and leisure
The home includes seven bedrooms, nine bathrooms, and multiple levels designed to balance privacy with shared spaces.
Additional rooms include a dedicated office with a wood-burning fireplace, a gym, and a media room. Each space follows the same design logic, with materials and sightlines aligned toward the surrounding landscape.



Direct beach access and outdoor spaces shaped around the coastline
The property includes direct access to the ocean beach, along with multiple outdoor areas arranged across different elevations.
These include patios, balconies, and an outdoor shower, as well as a rooftop space that offers additional potential for customization.

The layout keeps the coastline within reach from nearly every part of the property.
A Bridgehampton oceanfront shaped by art, design, and setting
At 15 Dune Road, the design decisions are tied closely to the owner’s background — not just in luxury real estate, but in art collecting and cultural circles.
The result is a home that was built with a specific purpose in mind, where architecture, materials, and setting are aligned from the outset.

Now listed for $45 million, the property offers a rare combination of location, scale, and intent — one that reflects both the Hamptons’ oceanfront market and the legacy of the individual who created it.
