One Bayfront Plaza would primarily consist of offices and hotel space, but also would include a retail mall, condominiums, and parking garage on the lower levels, as well as possibly an observation deck at the top.

[5] One Bayfront Plaza has gone through several design revisions since its original proposal as a single, 80-floor, 1,180 feet (360 m) tower, which exceeded height restrictions.

The development was planned to include an adjacent, connected 850-room hotel tower referred to as 100 South Biscayne II.

The FAA reasoned that the skyscrapers interfered with their radar, in addition to being a physical hazard to landing planes.

[8] The redesigned One Bayfront Plaza was approved at its exceptional height of 1,049 feet due to its determination by the city as a significant landmark and because it got a Major Use Special Permit (MUSP).

[2] The major feature of the new design was the incorporation of a separate hotel building to be located adjacent to the tower.

In the fall of 2008, the building's height was scaled back again slightly due to new zoning laws to its current design as a single, 80-floor, 1,010-foot tower.

[A] This design of the tower was to incorporate fluid dampers used to absorb wind gusts and create energy efficiency for the skyscraper.

A pedestrian bridge will connect it to the Bayfront Park Metromover station located directly in front of it.

However, as recently as March 2011, three-year leases were being offered on the existing building, suggesting a new start date no earlier than 2014.

[2] One Bayfront Plaza would surpass the 868-foot (265 m) Panorama Tower, which is currently the tallest building both in Miami and the state of Florida.

[18] 100 South Biscayne II was the name of the proposed hotel tower that would have been located adjacent to the main One Bayfront Plaza tower in the 100 South Biscayne complex, connected at the bottom by the large retail area and parking garage making up the podium.
