New York City has a once-in-a-lifetime opportunity to create a new iconic landmark in Midtown, potentially with the help of Donald Trump. However, the proposed redevelopment may be compromised due to the presence of Madison Square Garden, which sits right on top of everything. James Dolan, who owns the Garden, has been adamant that his prize building is staying where it is. Of at least three plans submitted to the federal Transportation Department’s beauty contest for the redevelopment, only one involves moving the Garden to a vacant block across the road to make way for a soaring classical architectural masterpiece. The Grand Penn Alliance has proposed a plan that includes a train hall that echoes the McKim, Mead & White architectural treasure that was demolished in 1964. However the final decision on the Grand Penn proposal is set to be made by next month.
