Good work.
The preservation of Louis Comfort Tiffany Stained Glass Rose Window at Saint Mark’s Episcopal Church in Berkeley, California is a winner for the 2025 Preservation Design Award for Craftsmanship/Preservation Technology.
Though initially thought to be a relatively small repair of two, stained glass panels, discoveries in the initial survey phase revealed major disrepair of the entire west wall. Each of the 17 multi-layered (platted) window panels were removed and conserved.
Concurrently, the metal frame and supporting wooden architectural structure were reconfigured and reinforced to provide a stable framework for the conserved panels to be reinstalled. The new frame also accommodated new protective glazing with ventilation to the interior with an innovative cantilevered central section of the frame.
Additionally, the church took advantage of accessibility provided by scaffolding to replicate the exterior star encircling the window as some material components were failing.
The project required collaboration between engineers, restoration woodworkers and metalsmiths, roofers, painters and stained glass preservation specialists.
