University of Oklahoma Gibbs College of Architecture Dean Hans E. Butzer returned to one of his most significant works on December 15, joining survivors and past and present board members for the groundbreaking of a $15.8 million expansion of the Oklahoma City National Memorial & Museum.
The event brought together the design team of Butzer, his wife and design partner Torrey Butzer, and exhibition designer Patrick Gallagher, alongside Bob Johnson, the memorial foundation's first chairman, and others who have been connected to the project since its inception following the April 19, 1995, bombing that claimed 168 lives.
Speaking to attendees on a cold December afternoon, Dean Butzer outlined how the expansion will transform the visitor experience by creating stronger connections between the museum's interior spaces and the outdoor memorial elements.

"We will be expanding outwards, moving out from the historic building closer to the street, to better engage the public, to be more welcoming," Butzer explained. The reconfigured entrance and children's area will provide two and a half times more space for visitors.
The expansion's design incorporates salvaged materials from the original Alfred P. Murrah Federal Building. Granite that has been preserved in storage since 1995 will greet visitors at the new entrance, while Vermont slate from the current children's area will be restored and repurposed. Even the existing entry tiles and signage will find new homes within the expanded facility.
A new southwest-facing entrance will open directly toward the memorial's Gates of Time, connected by a glass elevator and grand staircase spanning three floors. The ground level will house an expanded lobby and retail space, while the second floor will feature a Civic Lab and recording studio. On the third floor, a new orientation gallery will help visitors understand the moments before 9:02 a.m. on that April morning.

The expanded lobby will accommodate large groups as they learn the story of the bombing, many for the first time. While most of the current exhibition spaces within the historic brick walls of the museum will remain intact, the addition will allow visitors to discover this story like never before.
Torrey Butzer emphasized the team's attention to continuity with the existing memorial. "We chose materials that felt like they belong, that they were of this place," she said, noting how the metal facade echoes the Gates of Time and the base stonework matches materials around the Survivor Tree.
A temporary lobby and limited gift shop are now open as site work progresses on what will be an approximately 16-month construction schedule.
During the Spring 2026 semester, students in Interior Design Studio IV and Graduate Studio IV gained hands-on experience in educational facility design through a semester-long partnership with MA+ Architecture.
The Christopher C. Gibbs College of Architecture congratulates Dr. Tammy McCuen, Robert E.

Following years of contributions to the College’s research and strategic initiatives, Gibbs College shares that Associate Dean for Research and External Engagement Angela M. Person, PhD, will step down from her position at Gibbs College as she moves to Tucson with her family, effective June 30, 2026.
