Complex Security in a
Compact Footprint

Johnson County New Century Adult Detention Center Expansion
New Century, Kansas, USA

“HOK brought an extensive command of every subject to their work, from the latest in ACA interpretations to security hardware details to courthouse organizational concepts. … They were prepared, responsive and insightful. They questioned our preconceptions and respectfully defended their positions when we challenged them. As a result, our work together has been very successful. We look forward to working with HOK again.”

J. Joseph Waters
Facilities Department Director, Johnson County

The innovative design for this 554-bed expansion incorporates several specialized housing configurations on a site originally planned for 96 beds.

HOK and Treanor Architects designed several housing types, including segregation, maximum security, special needs and medium/minimum security. The compact footprint for this expansion follows the existing facility’s triangular configuration and fits within the existing road and utility network.

The poured-in-place, flat-slab concrete structural system provides flexibility to stack different housing unit configurations. Horizontal rear service chases simplified construction and allow staff to do maintenance work without entering the secure housing unit.

The team planned each housing unit to optimize sightlines and capture borrowed light. The separate segregation unit has a central control room that allows for direct observation of each of the four single-level housing wings, outdoor exercise areas and dayrooms. Detention center guards directly supervise the other housing units.
