The Center for the Preservation of Modernism at Thomas Jefferson University will host a panel, tour and demonstration of the Hassrick House as part of the 2022 Docomomo US National Symposium. The event will be comprised of two parts: 1) talks and panel discussion by modern conservation experts and 2) conservation workshop offering demonstrations of modern conservation techniques as they relate to the preservation of The Hassrick House, designed by Richard Neutra and completed in 1961.

The Hassrick House will serve as a case study for the preservation and conservation of mid-century modern residences. Discussion and demonstrations focus upon ways to conserve modern design, materials, and details, such as Pennsylvania Bethayres concrete block, large expanses of glass doors and windows, flat roofs, and cork flooring. Preservation experts will explain and demonstrate advanced digital techniques, including thermography, photogrammetry and LiDAR scanning.
