The life's work of Arthur and Cynthia Wood, Broken Angel was cited for numerous building code violations after a fire in 2006, and the Woods were forced to dismantle an incredible, multi-story rooftop structure they had built. For a look at many of the building's unique features, check out this photo gallery posted by the Woods' son, Chris. The NY Times also has a terrific shot of the whole complex.
Cynthia died in 2010 after a battle with liver cancer, and Arthur lives here alone now. Brandon Stanton spent some time with him last summer, and wrote about the experience for his Humans of New York project.
