You may have noticed construction work speeding along at the corner of 13th St. and 4th Ave. This is to be an 11-story, 162-room hotel in the medium price range. It’s being built by Sam Chang, the king of New York hotel development. He’s famous for finding ways to squeeze hotels onto tiny lots. In this case he’s keeping the facade of the former building as a kind of pedestal. Unusually sensitive for a developer who is usually accused of having no architectural taste whatsoever.
