830 Brickell did something Miami hadn’t seen in decades: it built a premier standalone office tower on spec and filled it before the doors opened. Rising 724 feet over the Brickell financial district, the 55-story tower leased out during construction to a tenant roster that reads like a relocation story for American finance and tech.
Project Scope. Developed by OKO Group and Cain International and designed by Adrian Smith + Gordon Gill, the firm behind some of the world’s tallest buildings, 830 Brickell delivers roughly 640,000 square feet of Class A office space. The tower topped out in 2023 and moved through phased occupancy as tenants built out their floors. Its roster includes Microsoft, Citadel, Kirkland & Ellis, Thoma Bravo and Santander, several of them firms that expanded or relocated to South Florida.
Why It Matters. For years Miami’s office market ran on converted space and mixed-use podiums. 830 Brickell proved there was real demand for trophy office product in the city, and its lease-up during construction validated the bet that the Sun Belt migration of capital was durable rather than a pandemic blip. It reset what a Miami office tower can command, the same trophy-office demand now showing up in markets like Austin’s Sixth and Guadalupe, and cleared the way for the next round of Brickell high-rise development.
