Around The Infinity






Who It's For
The Infinity is for buyers who want full service and a real choice of homes: downtown workers who want to walk to the office, swimmers who will actually use the lap pool, and anyone who wants Bay Bridge views. The mid-rises are one of the better values for a full-service building in South Beach.
The Backstory: A Whaling Ship Underneath
The Infinity was built on a surface parking lot at Folsom and Spear. During excavation in 2005, crews found a buried ship about 20 feet below the street, sitting on fill from an old ship-breaking yard. It turned out to be the Candace, a whaler built in 1818 that ended its days on the Gold Rush waterfront. The project itself was approved in 2003 alongside its sister, Lumina. Tishman Speyer finished the four buildings in 2008 with Heller Manus Architects and Arquitectonica, and the curving glass towers are still the signature of the South Beach skyline.
Floor Plans
One-bedrooms are mostly about 650 to 850 square feet, two-bedrooms about 1,150 to 1,350, and three-bedrooms start around 1,300 square feet, with penthouses up to about 3,000. Plan names differ by building, so start with the address. Insiders will find the plans and documents we have on file at the bottom of this page.
