Our team began the immense task of repairing and stabilizing the building envelope. Crews replaced the magnificent metal and slate roofs, locating matching slate and a matte-finished stainless steel to mimic the original tin. A new steel structure was installed to augment the original iron trusses and to improve seismic, wind, blast and snow-load performance. Inside, teams removed extraneous infill walls and uncovered elegant arched openings to recreate the original sight lines, allowing interiors to bask in natural light. Ornamental metal work was removed, restored and replaced, and the 17 historic interior spaces were exposed and emphasized.
