Demolition is now underway at 511 NE 15th Street where Mandala Holdings is planning to build a 40-story hotel tower designed by Allan Shulman. In May the developers received a demolition permit for the 4,457 SF of existing buildings on the 11,700 SF site, although a construction permit to proceed with the new tower has not yet been applied for. The new tower will rise 580' and feature 270 hotel rooms, a rooftop bar, office space and retail.  The tower's design will feature a unique curtain wall system of colored glass. The property, which is adjacent to the future site of Resorts World Miami, is located the main artery leading onto the Venetian Causeway and at the base of the Adrienne Arsht Center Metromover. Mandala Holdings purchased the lot for $8 million in 2016. PROFILEmiami previously reported that The Courtyard by Marriott would be the operating entity and that the project was expected to be completed by 2020.
