HMN Architects, Inc. worked with Clay County on a 28-Bed Detention Center and Sheriff's Office. This new building is on the site of the existing Sheriff's Office. Merging the jail with the Sheriff's Office meant that there were a variety of stakeholders involved in the design process. Recognizing the varied needs of staff and incorporating them into the design proved challenging, but HMN Architects listened to the client and was able to include their requests within the budget. By meeting with the Sheriff, Chief Deputy, Investigator, Jail Administrator and Board of Supervisors, HMN was able to design a facility that worked for all parties.

The new facility has 20 general population beds with another six dedicated to work release and two for medical / administrative segregation. The new booking area has six holding cells and gives the County a larger capacity for booking, along with the ability to classify inmates despite their small bed count. Using an indirect, single post supervision style, the jail has five dayrooms. The space also includes a warming kitchen, laundry and an indoor/outdoor exercise yard.

There are a few design features requested by the County that are unique to a jail of this size. The large evidence storage has been designed to accommodate the County's growing capabilities, and the evidence processing area has pass-through lockers. It was important to the Sheriff to provide a squad room with individual work spaces for road patrol, which was incorporated into the design. To accommodate the colder climate, the vehicular sally port allows for indoor parking. The facility also has a large training and meeting space that will be used by the community, as well as law enforcement. This area can also double as an emergency operation center with a concrete lid and masonry walls.

In terms of the exterior design, the administration uses fiber reinforced concrete skin over metal studs with a mixture of low slope roofs and standing metal seam slopes. Two colors of precast panels were used for the detention area. To design for the climate, the team utilized sustainability concepts and geothermal technology to increase efficiency.

The HMN team included a local architect with strong ties to the community who had an understanding of the community's design aesthetic.
