Cadillac Place

The former GM world Headquarters, now known as Cadillac Place, is a symbol of Detroit’s history as the industrial capital of the United States. The interior of this National Landmark features a stunning, historic plaster ceiling comprised of rows of hexagonal plaster ornament. In 2011 sections of the ceiling fell due to failed restoration attempts.

EverGreene was selected to fortify the ceiling support system, restore the ornamental plaster elements, and apply painted finishes of the entire 30 x 170’ ceiling. To match new work with the old, EverGreene conducted a paint analysis, and forensic studies of color samples in our laboratory and on-site. Custom colors, glazes, and techniques were created to give the ceiling the appearance of having been undisturbed since its original 1923 unveiling. The project involved the fabrication and casting many different decorative plaster pieces.

All work was completed in the evening to minimize interference with Cadillac Place’s operations. By night the lobby was a construction site, by day it welcomed office workers and visitors to a clean, safe environment.
