According to Curbed NY , a proposal for Roosevelt Island by architect Victor Ostojic:

… imagines a cantilevered, glass-covered ferry terminal on the western side of the island, which would serve as a major transportation hub for the rapidly-developing area…

and:

… the cantilevered building would have ground-floor retail, a food court, offices in the middle portion, and a luxury hotel on top. In addition, Ostojic has proposed digging out the island behind this new ferry terminal and creating a marina that would better connect the island to Queens…
