Johnson County’s new courthouse in Olathe, Kansas, pairs a contemporary civic image with references to the region’s geology and history. A curving Kansas-limestone screen wall frames the main entrance, while glass curtainwall and punched windows make the building feel more connected to its surroundings. Inside, a two-story public lobby called the “Emporium of Justice” brings frequently used services to the front door instead of hiding them deep in an institutional plan.
The courthouse is more than a prominent façade. The project profile published by Building Enclosure on February 3, 2021, describes a 356,831-square-foot facility with 28 courtrooms, capacity for six to eight more, separate secure circulation for in-custody transfers, and sustainability targets intended to support a 75-year service horizon. Those details are reported project claims; current certification, measured energy performance, and present-day visitor procedures were not independently confirmed.

A civic exterior rooted in Kansas
The limestone screen wall
The most recognizable gesture is a curving screen wall clad in Kansas limestone at the principal entrance. The project profile says the form draws from Kansas geology and from the Conestoga wagons associated with the nearby Santa Fe Trail. That reference gives the entry a local narrative without reproducing a historical building style.
As a screen, the wall does several jobs at once. It establishes a visible threshold for a large public building, gives the entry a solid civic presence, and creates a surface whose texture can be read at pedestrian scale. The curvature also contrasts with the more regular geometry expected from courtrooms, offices, and circulation corridors behind it.
Glass used to signal access
Glass curtainwall and punched windows support the design’s stated sense of openness between inside and outside. In a courthouse, transparency is symbolic as well as practical: people arriving for jury service, hearings, records, or assistance can see activity rather than facing an opaque administrative block.
That openness is selective. The public-facing glazing does not eliminate the need for controlled entries, screening, or separated circulation. Instead, the envelope presents an approachable civic face while the interior plan handles the security requirements that courts demand.
The “Emporium of Justice” makes public services visible
The main entrance leads to a two-story lobby named the “Emporium of Justice.” According to the project profile, the concept places high-use public functions near the entry and makes those functions legible to visitors. Curtis Fentress, principal in charge of design at Fentress Architects, described it this way: “The ‘Emporium of Justice’ is an innovative design feature that was incorporated into the building’s architecture to create a truly open, accessible, and convenient environment for the community.”
Services located near the front door
The named services are:
- Law Library
- Court Administration
- District Attorney
- Court Clerk
- Help Center
- Court Trustee
- Justice Information Management
- Sheriff’s Office
Grouping these destinations at the public threshold can reduce the intimidating effect of a large courthouse. A visitor who needs a clerk, help center, or trustee service can orient from a common lobby rather than searching through secured courtroom floors. The arrangement also separates public transactions from spaces where judges, jurors, staff, and in-custody individuals require different levels of control.
Rank #2
Openness without exposing sensitive movement
The lobby’s visibility should not be mistaken for unrestricted access throughout the building. Court facilities must distinguish between public queuing, staff work areas, courtroom circulation, jury movement, and prisoner transport. The courthouse addresses that conflict through zoning: public services are presented openly, while secure elevators, holding areas, and transfer routes remain controlled.

A broad judicial program
The reported program includes 28 courtrooms and hearing rooms supporting criminal, civil, juvenile, child-in-need-of-care (CINC), family, probate, traffic, and small-claims matters. That range matters because each case type can create different scheduling, technology, privacy, and participant requirements.
The plan also reserves flexible space for six to eight additional courtrooms. The project profile does not state exactly when those rooms would be built out or what construction cost would apply. The important planning decision is that future expansion was considered in the original layout rather than left entirely to an addition that might disrupt operations.
Raised access flooring in the well
The courtrooms are described as adaptable, with raised access flooring in the well area. The underfloor zone can make it easier to reroute power, data, audio-visual connections, and other services when courtroom technology or furniture arrangements change. In a facility expected to serve for decades, that capacity can reduce the need for disruptive demolition.
Raised access flooring does not make every courtroom reconfigurable for every use. Fixed walls, sightlines, acoustics, judicial protocols, and life-safety systems still constrain changes. Its value is more specific: it provides a service-distribution strategy that can accommodate upgrades without treating the original technology layout as permanent.

Security is designed into circulation
Security is not presented as a separate equipment package in the project profile; it is embedded in the building’s routes and levels. Brian Chaffee, a Fentress principal and FAIA, summarized the design priorities as: “Security, flexibility, and efficiency were key elements of our design.”
Rank #3
In-custody transfer route
The basement has direct vehicle access for in-custody transfers. The profile also describes an underground tunnel connecting the courthouse to the Central Booking Facility. This arrangement can move detainees between facilities without sending them through public entrances, sidewalks, or shared lobbies.
Controlled vertical movement
Secure elevators and temporary holding areas support the same separation strategy. Public elevators and circulation can serve visitors and court participants while secure vertical routes handle movement that must remain out of public view. The February 3, 2021, Building Enclosure profile reports these as design details, not as the result of an independent security assessment.
Site stand-off
A 50-foot stand-off around the site is another reported security measure. A stand-off creates distance between vehicles and the building envelope, giving site planning a role in threat mitigation. The profile does not identify the specific engineering standard, threat model, or operational procedures used to establish that dimension.
Spaces that support jurors, staff, and community use
Jury assembly and deliberation
The jury assembly space connects to a community room and an outdoor terrace. That relationship gives jury operations access to a larger communal area while providing an exterior setting within the courthouse program. Jury deliberation suites are described as having access to daylight, an important quality for people who may spend long periods in concentrated discussion.
Daylight access is not a substitute for acoustic privacy or controlled circulation. Deliberation areas still need to prevent contact with unauthorized people and avoid visual or audible exposure to courtroom activity. The design’s reported approach combines those operational requirements with a less enclosed environment.
“Open Prairie” public art
The building includes a public art installation titled “Open Prairie” by Ball-Nogues studio. Its inclusion places an artistic interpretation of the region inside a justice facility whose exterior already references Kansas landscape and history. The available project description does not provide the installation’s dimensions, materials, commissioning budget, or maintenance plan.
Rank #4
District Attorney workplace
The District Attorney’s office occupies a floor with open workspaces and collaboration areas. That workplace pattern suggests an emphasis on shared work and case coordination rather than a fully cellular office arrangement. The profile does not state how private attorney-client meetings, records storage, or security controls are handled within that floor.
Sustainability goals and the limits of the evidence
The courthouse was designed with a goal of LEED Gold and according to WELL Building Institute principles. The profile lists several strategies:
- Daylighting
- Water-efficient plumbing
- Energy-efficient building systems
- Measures intended to reduce the heat-island effect
- Low-emitting materials
- Durable materials selected for long service
The county also set a 30 percent energy-reduction goal. Because the source reports an objective rather than post-occupancy data, it would be inaccurate to describe the building as having achieved that reduction. The same caution applies to LEED Gold and WELL: the project was aimed at those frameworks, but the available material does not confirm certification.
Why durability is a sustainability issue here
A courthouse planned for a 75-year service horizon must be evaluated beyond its opening-day energy model. Durable exterior materials, accessible building services, and adaptable courtrooms can extend useful life by making repairs and upgrades less disruptive. The reported Kansas limestone screen wall, raised access flooring, and reserved courtroom capacity all fit that long-range logic, although actual lifecycle performance would require operational data.

The project description anticipates growth of 10,000 residents per year. That assumption helps explain why the design combines a large initial courtroom program with space for six to eight more rooms. It also explains the emphasis on an easily understood public lobby: increasing case volume can increase the number of occasional visitors who are unfamiliar with courthouse procedures.
Growth planning has trade-offs. Unbuilt expansion space can preserve flexibility, but it also occupies area that may not generate immediate operational value. A future build-out must maintain secure circulation, mechanical capacity, technology infrastructure, and life-safety separation. The source does not state whether those future systems were sized for all additional courtrooms or how expansion would be phased.
What the design says about contemporary civic architecture
The courthouse’s design language combines three ideas that can conflict in public projects:
- Institutional dignity: the limestone screen wall and two-story entry give the judicial function a clear civic presence.
- Public accessibility: the “Emporium of Justice” places essential services where visitors can find them and uses glazing to communicate openness.
- Operational control: basement transfers, a tunnel, secure elevators, holding areas, and site stand-off keep sensitive movement separate from public activity.
That combination is the project’s central architectural argument. Openness is expressed at the envelope and public lobby, while security is handled through circulation, zoning, and site distance rather than by making every part of the building look defensive.
At the virtual opening ceremony, Marla Luckert, chief justice of the Kansas Supreme Court, said: “Its beautiful design creates an image that conveys and reflects a sense of the importance of the judicial process and the values of the judicial system—openness and fairness.” The statement captures the intended public message, while the actual success of that message depends on wayfinding, staffing, courtroom operations, and visitor experience that are not documented in the available profile.

How to read the project’s claims responsibly
The courthouse profile provides a detailed account of design intent and reported program. It does not independently verify current certification status, energy savings, post-occupancy performance, or public access procedures. Readers looking for present-day visiting information should confirm hours, screening rules, accessible entrances, and courtroom schedules with Johnson County before traveling.
For architects, contractors, and owners, the more durable lesson is the coordination between image and infrastructure. Local material references establish identity; a visible service lobby improves orientation; raised access flooring protects future technology changes; and secure routes are planned as part of the building rather than appended after the design is complete.
Johnson County’s courthouse therefore stands out not because it chooses openness over security, but because it gives each requirement a different architectural response. The public sees limestone, glass, daylight, art, and an identifiable front door. Behind that civic face, adaptable rooms, reserved capacity, controlled circulation, and long-term material strategies are intended to keep the facility useful as the county changes.
