One Police Plaza is rectangular in plan and is an inverted pyramid in elevation. It is a 13-level, horizontally-oriented brutalist building designed by Gruzen and Partners in 1973. A expansion project was completed in 2011. Although the project did not add any new floors to the building, it did add new computers and equipment. Angry Lower Manhattan residents held a rally on August 27, 2008 near One Police Plaza to protest the addition, and tenants of three neighboring co-ops filed a lawsuit to force the NYPD to undergo environmental and land use reviews.
