Ultra-exclusive oceanfront living in Miami Beach is rare enough — but direct sand frontage inside a private gated enclave is almost unheard of.
That’s what makes Côte de Mar, a newly built $40 million architectural estate in Altos Del Mar, such a standout.
Designed as a sculptural, three-level modern retreat with its own private beach access, the residence offers 6,350 square feet of clean-lined coastal living shaped around Atlantic views.
Listed by Ruthie and Ethan Assouline of The Assouline Team at Douglas Elliman, the property sits on a 16,770-square-foot lot within Miami Beach’s only oceanfront gated community, long considered one of the city’s hardest-to-access pockets of real estate.
The home feels equal parts resort, gallery, and private escape — a contemporary statement piece designed around light, water, and indoor-outdoor flow.
A modern coastal design shaped by light and the ocean
Côte de Mar immediately sets a tone of calm architectural precision.
A sculptural façade of clean vertical lines and layering leads into a dramatic double-height entry, where natural light spills across stone floors and frames uninterrupted beach views.
The main level is designed for effortless flow with a sunken living room, elevator access, and a glass-encased wine cellar that anchors the central gathering spaces
The main kitchen combines clean architectural lines with luxurious utility: professional-grade appliances, minimalist cabinetry, and views that draw the ocean directly into the cooking space.
With lower level entertaining spaces
On the lower level, a secondary entertaining kitchen opens straight to the backyard, ideal for poolside gatherings, oceanfront dinners, and large-scale hosting.
Four secondary bedroom suites — each with walk-in closets and en-suite baths — occupy this floor, creating a rare sense of separation between guest spaces and the upper-level private quarters.
An entire third floor devoted to the oceanfront primary suite
In a design move that elevates the home beyond standard oceanfront builds, the entire third floor serves as the private primary level.
Wrapped in glass and opening to a spacious terrace, the suite delivers sweeping blue-water views at sunrise, sunset, and throughout the day
Every space is designed with a clean coastal aesthetic, creating a home that’s both visually striking and functional.
Dual walk-in closets, a spa-inspired bath, and a private lounge area complete the space, giving the primary suite the feel of a standalone retreat.
A private office, staff suite, and six-car parking bring function to the footprint
Beyond the architectural flash, the home offers practical amenities for long-term living, including:
- A private office with its own entrance
- Dedicated staff quarters
- Parking for up to six cars
- Solar panels for added efficiency
Rooftop views that define Miami Beach living
Above the primary suite, a full rooftop terrace offers panoramic views of the Atlantic coastline, Altos Del Mar’s contemporary estates, and the Miami Beach skyline.
Designed for sunrises, moonlit gatherings, and everything in between, the rooftop adds a signature touch to the property’s vertical living experience.
Outside, a saltwater lap pool stretches toward the dunes
Surrounded by multiple lounge areas, a sunken seating zone, and a private pathway that leads directly onto the sand — a defining feature of the property.
A rare oceanfront opportunity inside Miami Beach’s most exclusive coastal enclave
Altos Del Mar, with its gated access and direct ocean frontage, remains one of Miami Beach’s most difficult communities to enter.
Côte de Mar represents a rare chance to secure a contemporary estate on the sand — complete with private beach access, resort-style amenities, and a level of design that pushes modern coastal architecture forward.
With only a handful of true oceanfront homes in the city, Côte de Mar stands as one of Miami Beach’s most compelling luxury offerings of the year.
