"Pyramid Apartment House" by Edwin A. Koch, as printed in Popular Science, July 1940.   "Carrying modern set-back architecture to its logical extreme, the huge building provides a private terrace, with penthouse airiness, for every tenant above the fourth floor. No windows face the interior, a naturally ventilated hollow core fourteen stories high. ... Open corners of the building’s cross-shaped base provide a two-way automobile drive, a parking space for visitors, and two covered garages for tenants."
