The beauty of New York City is that it’s always evolving, with modern new towers springing up next to iconic skyscrapers. The Big Apple’s famed skyline is always in flux, and perhaps nothing illustrates that point better than our Photo of the Week, which was taken (and tweeted) by CORE CEO Shaun Osher — who wisely pointed out that both buildings, the landmark Madison Avenue Clocktower and the glassy One Madison Park, happen to be vacant at the moment. Empty or not (there are big plans to change the fortunes of both in the near future), they make for a fascinating pair of neighbors.
