7. The Corbin Building (next to Fulton Center)

The Corbin Building is now attached to the Fulton Center Transit Hub, and got a renovation thanks to that project. In fact, the quaint brick building was almost demolished but preservationists convinced the MTA to save it. A new foundation had to be dug for the building (by hand because the site was too narrow for machines!) and significant archeological finds from the work are now in the NYC Archaeological Repository.
