Kraner looked at modern-day police headquarters as well as cathedrals and old prisons for the three-story Gotham Police Precinct. Kraner was influenced by the aesthetic tone of the film Seven, "It’s dark but also very fluid in terms of the period it’s set in.""It’s timeless and not contemporary. We were very vague about the period". Graves added church lights to "bring a sense of the past to life and add a bit of character to the space." A gargoyle looms over the precinct’s bullpen.
