Bracke-Hayes-Miller-Mahon Architects (BHMM) of Davenport began working with the parish in 2012 to develop a plan to update the parish facilities. A new handicap-accessible entrance on the east side of the cathedral was completed in January 2013. In September 2016 construction began on the new hall immediately behind the cathedral. It includes a gathering space, restrooms, a handicap-accessible entrance on the west side, a reception hall, and classrooms. Mark Miller was the principal architect and Swanson Construction of Bettendorf was the contractor. The hall was dedicated by Bishop Thomas Zinkula on November 19, 2017. It was named for parishioners Weir and Pat Sears who gave the first $1 million for the $7 million project. The gathering space was named in honor of Antoine and Marguerite LeClaire. A new parking lot completed the project.
