The Miami luxury office market just received a massive vote of confidence with a $100 million redevelopment that transforms traditional workspace into a five-star wellness destination. Located at 1691 Michigan Avenue, just steps from the world-famous Lincoln Road promenade in Miami Beach, this project signals a new era for how the ultra-wealthy work, heal, and socialize in South Florida.
Developer Robert Rivani has branded the 163,000-square-foot building as “Class X” ā a category-defying concept that combines luxury hospitality, cutting-edge wellness technology, and premium office space under one roof. The project comes as Miami-Dade County now hosts 19 of Florida’s 20 richest billionaires, according to data published earlier in 2026.
Miami Billionaire Migration Reshapes Real Estate
The transformation of Miami from vacation playground to billionaire headquarters has accelerated dramatically in recent years. In 2025, a home in the city sold for more than $100 million for the first time ever, marking a historic milestone for the South Florida real estate market.
Jeff Bezos has assembled more than $230 million in property on Indian Creek Island, the guarded enclave known as the “Billionaire Bunker.” Citadel CEO Ken Griffin relocated his company’s headquarters to Miami, while tech titans Mark Zuckerberg, Larry Page, and Peter Thiel have all purchased property in the area.
The draw remains powerful: no state income tax, year-round sunshine, and a business-friendly climate that the COVID-era remote work revolution only enhanced. Meanwhile, Miami’s millionaire population has grown 75% over the past decade, fueled partly by California’s Proposition 40 ā a proposed one-time 5% wealth tax on billionaires that has sent some Californians packing for the East Coast.
Class X Luxury Office Concept Redefines Workspace
Robert Rivani, a Beverly Hills-born developer who built his career buying shopping centers after the 2008 crash and later pivoted into Miami hospitality, sees opportunity where others see crisis. While many investors fled the office market, he dove in headfirst.
“When everyone thinks it’s falling apart, that’s when we’re jumping in.”
The building, formerly known as The Lincoln, was purchased for $62.5 million in 2024. The prestigious Rockwell Group gutted and redesigned the space into something resembling a five-star hotel rather than a traditional office environment. Rivani dismissed conventional amenities like gym memberships and free snacks as “gimmicky” approaches to tenant retention.
For residents tracking Miami’s evolving identity as a world-class city, this development represents another milestone in the region’s transformation into a global hub for wealth and wellness.
Wellness Amenities Include Stem Cell Clinic
The amenity deck serves as the heart of the Class X development, featuring an unprecedented array of health and wellness services. The Monarch Athletic Club performance center anchors the wellness offerings, complete with cold plunge pools and infrared saunas ā marking the club’s first location outside of California.
Perhaps most striking is the on-site stem cell clinic where a longevity doctor administers peptide treatments and other cutting-edge therapies. This focus on health optimization reflects Rivani’s personal journey with autoimmune issues, which inspired the project’s wellness-centric design philosophy.
“The [two things] money can’t buy are time and health. And that’s where the concept came together. I said: ‘Okay, we’re not doing office. We are defining what office should look, feel, act like.’ And that’s where the brand and the whole concept came about.”
Additional wellness features include a members-only speakeasy that remains private for tenants during business hours but opens to the public after hours. The development also boasts an omakase restaurant, dedicated concierge services, and a hospitality director managing the guest experience.
Vegas-Style Valet Creates Dramatic Arrival
The Class X valet experience takes inspiration from Las Vegas showmanship, creating a theatrical entrance that matches the building’s luxury positioning. Rivani designed the arrival sequence to impress from the very first moment.
“Our valet is supposed to be this shock-and-awe, Vegas-style valet. You have a twinkle-light ceiling. As soon as you hit the pavement, it follows your car all the way through in the valet with 150 feet of linear waterfall.”
This attention to experiential detail distinguishes Class X from conventional office developments. Every touchpoint, from the twinkle-light ceiling to the 150-foot waterfall feature, reinforces the message that this is not your typical workspace. The valet service sets the tone for what tenants and their guests can expect throughout the building.

Celebrity and Corporate Tenants Anchor Development
The Miami luxury office project has already secured an impressive roster of high-profile tenants that validates the Class X concept. Playboy is relocating its global headquarters from Los Angeles to a 20,000-square-foot penthouse in the building on a 10-year lease ā a major coup for the Miami Beach location.
Shark Tank star Daymond John has signed on as a tenant, bringing his entrepreneurial empire to the Class X building. Major financial institutions including Morgan Stanley and Raymond James have committed to space, alongside technology company Wix and media giant Comcast.
Real estate firm Coldwell rounds out the corporate tenant roster, while a collection of longevity-focused businesses aligns with the building’s wellness mission. This diverse mix of entertainment brands, financial services firms, and technology companies demonstrates broad market appeal for the luxury office concept.
The tenant roster reflects Miami’s emergence as a serious business destination, not just a party town. Companies that once would have automatically chosen New York or Los Angeles are now selecting South Florida as their base of operations, attracted by the same factors drawing individual billionaires to the region.
For those following Miami’s rapid evolution, the Class X development represents more than just a real estate project ā it’s a statement about the city’s future as a global business capital. With its wellness amenities, celebrity tenants, and luxury positioning, the building at 1691 Michigan Avenue offers a glimpse of how the ultra-wealthy will work in the coming years.
The $100 million investment arrives as Miami continues attracting wealth at unprecedented rates, with the city’s millionaire population growth of 75% over the past decade showing no signs of slowing. As Class X welcomes its first tenants, Playboy’s official headquarters relocation from Los Angeles is expected to complete by early 2027, marking another chapter in Miami’s transformation into the nation’s premier destination for luxury living and working.
