Plaza Bonus

New York / Seattle

In exchange for providing certain public amenities, buildings may in some cases surpass the maximal values that normally apply (max. building height, utilization, etc.). A catalog specifies the levels of such bonuses for specific public features.

  • Another beautiful example of the outcome of the Plaza Bonus Rule, the Citi Corp Building from 1977.
