[2][4] The complex is named after New Jersey Democratic politician Frank J. Guarini.

The complex, while sharing a single foundation, includes three buildings: a five-story offices and courthouses, a one-and-half story building for Surrogate court, and a six-story, 471-space parking garage.

A three-story ramp will connect the lobby with the main courthouse, providing access while avoiding the higher security lower levels.

[4][5] The building will have several structural safety features, including ballistic rated windows and protection from a total collapse due to an explosion.

[5] The new complex will also seek to address security issues that the previous building had, including separate entrances for the public, staff, and inmates, as well as having areas with differing levels of security based on their function.
