Site Renovation, Interior Renovation & Restoration
Garmann Miller has worked with Miami County on multiple phases of improvements to its historic 1888 courthouse, preserving the character of the landmark while improving safety, accessibility, energy efficiency, and the public experience.
The initial phase focused largely on the courthouse grounds and adjacent safety building. Existing conditions presented several safety concerns, including poor lighting, trip hazards, deteriorated pavement, and sunken areas above abandoned tunnels. Improvements included waterproofing the pedestrian tunnel between the two buildings and the courthouse below grade, abandoning several original brick and dirt tunnels, and reinforcing a tunnel for continued infrastructure use.
The project also revitalized the courthouse plaza while drawing inspiration from the building’s history. New site lights were selected to resemble gas lanterns, and the post-top fixtures on the courthouse's grand stairs were restored. Salvaged materials were incorporated throughout the design, including original wall stones reused as bench seating and stone from the former county jail incorporated into a new water feature. The plaza’s brick paving pattern was inspired by tile found inside the courthouse, further connecting the exterior improvements to the historic building.
Additional upgrades improved pedestrian access and ADA accessibility, increased exterior lighting for safety and security, enhanced wayfinding, and created a more welcoming space for community events. A color-changing lighting system was also installed to illuminate the courthouse, and the local police memorial was given a more prominent location accented by blue light.
More recently, GM’s work moved inside the courthouse with upgrades to the security checkpoint at the east entrance and restoration of the third-floor Grand Courtroom. The courtroom was repainted and received new wood benches and five pendant light fixtures, while existing woodwork was carefully restored.
The improvements continued throughout the three-story courthouse, including restoration and repainting of the second- and third-floor corridors. Updated signage and new lighting selected to complement the building’s late-19th-century character further refreshed the historic spaces.
Additionally, 105 windows were replaced throughout all three floors to improve energy efficiency and support the courthouse’s long-term preservation. The new aluminum windows were carefully detailed to replicate the appearance of the original wood windows, providing modern performance while maintaining the historic aesthetic.
Together, the improvements balance historic preservation with modern functionality, helping Miami County extend the life of its landmark courthouse while creating a more accessible and welcoming environment for the community.
