Passive security in architecture can be broadly defined as “a design feature which deters threats while remaining largely invisible to its users.” 

Architectural applications which employ passive security can take many forms, from entire building annexes, to artfully perforated fence systems, to blockades disguised as art installations. What these security measures have in common is a strategy for reducing conspicuous security measures. It's the idea that threat deterrents don't have to be overtly visible. 

The benefit of this philosophy is an improvement in quality of life for a building's occupants. Learn more about passive security here, or view below an updated listing of projects completed by Zahner which feature this design philosophy.
