In mid-2007, GIPEC announced five finalist design teams, namely West 8, Diller Scofidio + Renfro, Rogers Marvel Architects, Quennell Rothschild & Partners, and SMWM. West 8 ultimately won the contest. The plan included of open space, as well as provided for the restoration of the historic district and a new park on the island's southern portion. Artificial hills were part of West 8's plan for the island, as were free bicycle rentals. Since the island was windy, West 8 designed their proposed topography to provide moments of shelter. Some plans were not implemented; these included an aerial gondola system designed by Santiago Calatrava, as well as a proposal by Center for Urban Real Estate (CURE) at Columbia University to physically connect Manhattan to Governors Island using landfill. A proposal to convert Castle Williams into a theater in the style of London's Globe Theatre was designed by architect Norman Foster in 2005, but was deemed unsuitable for the castle's design. Additionally, in 2008, there were unrealized plans to relocate the security and ticketing checkpoints for the Liberty Island and Ellis Island tourist ferries from the Battery to Governors Island, bringing as many as 500,000 additional people to Governors Island each year.
