Chateau Group is requesting permission from the FAA to build two 700-foot towers at 600 Biscayne Boulevard and 700 Biscayne Boulevard.
Two separate condo towers had been proposed for the sites in the mid-2000s, including a controversial proposal behind and adjacent to the Freedom Tower. The properties were later acquired by Chateau Group, and are used for surface parking an billboard advertising.
In 2013, the FAA issued approval to build up to 700 feet on both sites. An extension was granted in 2015, but the approval is set to expire in January 2017.
