One Kane is rising on Bay Harbor Islands as a waterfront trophy office tailored for the ultrawealthy, promising private yacht slips and dock-to-desk access that could change where Miami’s richest decide to actually show up for work. Developers are pitching the boutique building as a headquarters-style hideaway, with large floor plates, stepped-up privacy and security, and terraces at every office to lure family offices and principal-led firms. With billionaire sales and record residential pricing nearby, One Kane is being sold as the live-work luxury anchor of Miami’s so-called Billionaire's Triangle.
A New Map For Miami Office Demand
The storyline around the project leans on a commissioned report that argues wealth migration is tugging top-tier office demand away from downtown and into enclave neighborhoods. The Analytics Miami study, cited by CityBiz, frames One Kane as a 126,000-square-foot Class A+ office with direct frontage on Indian Creek, private dockage, and floor plates of roughly 12,000 to 18,000 square feet designed for headquarters-style occupancy. The report projects record-high global HNWI relocations and growing centi-millionaire populations as the engine behind a new $100-plus per square foot trophy lease tier in South Florida.
Developers, Financing And Approvals
The project is a joint venture between Miami-based Taubco and New York’s Landau Properties, which in late 2024 locked in construction financing to push the plan forward. Commercial Observer reported that Landau and Taubco secured a $74 million loan from 3650 Capital for the Bay Harbor site at 9551 East Bay Harbor Drive, and Bay Harbor Islands records show repeated site-plan approvals and revisions for One Kane Concourse. Cushman & Wakefield is handling leasing for the property, signaling that brokers are already quietly shopping large, single-floor blocks to financial and private-wealth tenants.
Bespoke Amenities For Family Offices
Developers and brokers are casting One Kane as a privacy-first alternative to Brickell and the urban core. "This is the only Class A+ waterfront office building on Bay Harbor Islands," Taubco principal Laura Tauber told CityBiz, while Jonathan Landau has emphasized the building’s private dock-to-desk access and large-format floor plates tailored to family offices. Planned perks include terraces at every office, private vehicular access, and a full-building generator to keep operations running when the lights go out elsewhere.
Pricing Benchmarks And The Trophy Market
Analysts say One Kane is arriving just as Miami’s highest-end office market is resetting its price ceiling. The Analytics Miami report tracks recent super-prime leases, from Tom Brady’s family office at The Well to UBS’s Coral Gables deal, and argues those tenants are creating a new $150-plus per square foot pricing framework. The Real Deal has also documented leases and letters of intent above $150 per square foot, and developers say discussions at One Kane have ranged between $175 and $200 per square foot, triple net.
What To Watch
All eyes will be on leasing chatter and whether family offices commit to full-floor headquarters instead of bite-size suites. Cushman & Wakefield’s property page lists about 73,973 square feet available and shows construction slated to begin in May 2027. If brokers can turn those letters of intent into signed pre-leases at the pricing being discussed, One Kane could lock in a new downtown-adjacent submarket where privacy and waterfront lifestyle command a serious premium. For now, the project stands as a flagship bet on South Florida’s wealth migration, and its lease-up will be a bellwether for how far Miami’s trophy-office boom is willing to go.
