Polk County Criminal Courts

OPN Architects as Architects

To transform a former eight-story county jail into a criminal courts facility, the top six floors were removed while the remaining two were taken down to structure. Three new floors were then added to create a five-level, 110,500 square-foot building. Use of Indiana limestone, glass curtainwalls, and zinc cladding at exteriors unify the urban courts campus and reinvent the nearly windowless brick façade of the 1980s-era jail.

On the public side of the courtrooms, wood and zinc elements identify the courtroom entrances and complement the exterior material pallet. These material accents along with clearly defined circulation and wayfinding, warm and effective daylighting, and comfortable seating combine to create a calming environment for what can be a chaotic, stressful experience.

As a criminal courthouse, maintaining separate circulation patterns for the public, judicial staff, and detainees to ensure public safety was critical to the design. Detainee holding in the basement allows a secure and isolated location for drop-offs while a separate stair and elevator core between courtrooms allows detainees to travel vertically. Judicial circulation is pulled to the exterior of the building, with general public access to the courtrooms at the center.

Six high-volume criminal courtrooms and four criminal jury courtrooms are now located in the building, with the flexibility to add five more in the future. These now serve court functions with adjacent support spaces for attorney negotiation space, jury deliberation, assembly rooms, clerk functions, chambers, detainee holding and support staff. All courtrooms are also equipped with state-of-the-art technology, security, and access control systems.
