Una Residences was developed by OKO Group, led by Vladislav Doronin (chairman of Aman Resorts), in partnership with London-based Cain International. The combination of Doronin’s global hospitality vision and Cain’s institutional capital creates a developer profile that’s unique in the Miami market. Here is the full story.
Who Is Vladislav Doronin and OKO Group?
Vladislav Doronin is one of those developers whose name you may not recognize immediately, but whose projects you’ve almost certainly seen or heard about. He’s the chairman and CEO of OKO Group, a New York-based real estate firm, and — crucially for understanding Una — the chairman of Aman Resorts, one of the most exclusive luxury hospitality brands on the planet.
Aman properties are legendary in the ultra-luxury travel world. They’re known for understated elegance, extraordinary locations, and a level of service and curation that goes well beyond what typical five-star hotels deliver. When you understand that the person directing Una’s development is the same person who oversees Aman’s global portfolio, the building’s design and amenity philosophy makes complete sense.
OKO Group’s portfolio spans New York and Miami, with projects that consistently target the ultra-luxury segment. Doronin doesn’t build commodity product — his developments are curated statements that draw from his hospitality background. For Una, that meant commissioning world-class architects, insisting on hospitality-grade amenity programming, and bringing in Enzo Enea for landscape design under his personal aesthetic direction.
What Is Cain International’s Role?
Cain International is the co-developer and financial partner for Una Residences. Based in London, Cain is a real estate investment firm with a substantial portfolio across luxury residential, hospitality, and commercial sectors in key global markets.
For buyers, Cain’s involvement provides an additional layer of institutional credibility. They bring rigorous financial discipline to the development process — the kind of oversight that ensures projects are properly capitalized and delivered on time. In a market where some developments have faced delays or financial complications, Cain’s track record is reassuring.
The OKO-Cain partnership combines creative vision (Doronin’s hospitality expertise and architectural ambition) with financial discipline (Cain’s institutional capital and project management rigor). That’s a powerful combination, and it shows in the execution at Una.
Why Did They Choose Adrian Smith + Gordon Gill?
When you’re Vladislav Doronin and you want to build a bayfront tower in Miami, you don’t hire a regional firm. You go to Adrian Smith + Gordon Gill Architecture — the firm that designed the Jeddah Tower, the building that will eventually surpass the Burj Khalifa as the world’s tallest structure.
AS+GG brought their signature approach to Una: forms inspired by classic yacht design, a sweeping glass curtain wall that maximizes panoramic views, and a sculptural presence on the skyline that sets the building apart from every other tower in the corridor. They also handled interior design, which is relatively unusual — typically, developers hire separate firms for interiors. The result is a more cohesive design vision from the lobby to the penthouse.
Enzo Enea’s landscape architecture completes the picture. Enea is one of the most sought-after landscape architects in the world, and his work at Una was directly guided by Doronin’s Aman aesthetic. The gardens and outdoor spaces aren’t typical Miami landscaping — they’re sculpted, intentional, and designed to create a sense of place that extends the interior experience outdoors.
What Does the Aman Connection Mean for Residents?
This is where it gets interesting. Doronin didn’t just design Una to look like an Aman property — he brought elements of the Aman service philosophy into the building’s lifestyle programming.
Una residents get a personal lifestyle curator, sommelier-curated wine events, a house car service to the airport and Grand Bay Beach Club in Key Biscayne, pet services, and a range of curated experiences that go beyond what typical condo associations provide. This is hospitality programming, not condo amenities — and the distinction matters.
The Grand Bay Beach Club access is worth highlighting specifically. This gives Una residents a private beach experience in Key Biscayne, extending the lifestyle beyond the building itself. It’s the kind of amenity that a developer with a hospitality background thinks of — and that a conventional developer simply wouldn’t.
How Does Developer Reputation Affect Your Investment?
In luxury real estate, the developer’s name carries real weight on the resale market. Buyers in the $5M+ range do their research — they want to know who built the building, what else they’ve done, and whether the quality of construction and management will hold up over time.
OKO Group and Cain International bring institutional credibility that smaller or less established developers can’t match. The Aman association specifically creates a brand halo that resonates with a global ultra-luxury buyer pool — the same people who book Aman resorts in Bali, Tokyo, and Venice are potential buyers for Una.
For context, compare that to some branded residence projects in Brickell where the hotel brand (like Cipriani or Waldorf Astoria) provides the name recognition. At Una, the developer himself provides that caliber of brand association through Aman — without the hotel management overhead and restrictions that come with branded residences.
That’s a nuance worth understanding: Una gives you the hospitality pedigree without the hotel brand limitations. You own a freehold residence in a building shaped by Aman’s founder, but you’re not subject to the rental restrictions or management fees that branded hotel residences typically impose.
