This design’s “Wow-factor” is the exterior plaza replacing the outdated rectory building. Inspired by St. Peter’s Square in Rome, the new plaza and enclosed colonnade make the cathedral church and chapel buildings much more visible and accessible, while providing a welcoming exterior urban space for downtown Indianapolis. The addition also includes a new main entrance from the parking lot, gathering space, large multi-purpose meeting room, and related support facilities. The interior renovation of the church features new radial seating around a modified sanctuary platform with an integral handicap ramp and a new marble altar, pulpit, and cathedra. The existing walls, classical pilasters, and coffered ceiling will receive a new color scheme featuring faux marbling, gold-leaf capitals, and blue highlights that correspond to the restored stained-glass windows and heighten the sense of the sacred. New decorative icons above the apse’s archway further accentuate the existing marble reredos and icon of Saints Peter and Paul. The former school building will be fully renovated and converted into a new rectory and pastoral center with the cathedral’s administrative offices. Other improvements include exterior restoration work, a new vehicular entrance and drop-off, and a new organ and lighting system in the cathedral.
