Commercial Projects

OSF Ministry Headquarters | $10,000,000

Renovation of a historic 275,865 sq ft building with seven levels, a penthouse, basement and sub-basement, originally built in 1905. Due to the block’s historic landmark status, the Illinois Historical Society and National Park Service had to sign off on everything. Along with providing a renewed space for 600 staff members, the building will utilize a café and curated outdoor areas to further engage the public and reinvigorate the community for decades to come. Completed in 2022.

ISU Bone Student Center | $4,200,000

Revitalization of the four-story, 118,669 sq ft, 47-year-old campus hub, which has 5,000 daily visitors and hosts more than 4,500 events each year, was much-needed. This work consisted of the main renovation which included Brown Ballroom, Welcome Center, relocating the catering kitchen, redesigning the loading dock, renovating the vacated second floor catering kitchen space to accommodate an expanded food court and Student Involvement Center, a new bookstore, improving entrances on the building’s west side, and renovating offices. The Concourses were renovated in two phases and there was a new restaurant added. Completed in 2020.

Bradley University Hayden Clark Alumni Center | $1.7 Million

The Hayden-Clark Alumni Center is an expansion of Bradley Hall, Bradley University’s founding structure constructed in 1897. The addition is styled after Collegiate Gothic architecture featured across campus, with a limestone exterior that matches the character of the existing building. The central tower is topped with four hand-carved gargoyles, two of which match those atop Bradley Hall and two that represent the campus’ western expansion.

Livingston County Courthouse Remodel | $860,000

To renovate the circa-1875 courthouse, we repaired the building’s windows, wood trim, doors, wainscot, and other finishes. The HVAC, plumbing, fire protection, security, and IT systems were replaced. The county supported our vision for restoring the courtroom space to its full height and original design, bringing the vaulted ceilings, hidden for years behind acoustic ceiling, back to life. In addition to the courtroom renovation, the main hallway and staircase were restored, offices were remodeled and reconfigured, and the basement was remodeled.

Bradley University Westlake Hall | $770,000

Our modernization of the second oldest building on campus has made Westlake Hall six times its original size, with a new center atrium, classrooms, labs, resource areas, an auditorium, offices, and conference spaces. All spaces in the building now provide students with an inviting place for collaboration, supporting cross-disciplinary study and problem-solving.

Methodist College of Nursing | $1 Million
