Structures / Hallidie Building
The Hallidie Building is an office building located at 130 Sutter Street, between Montgomery Street and Kearny Street. It is credited as the first West Coast building to feature glass curtain walls over a steel frame.
The building was designed by architect Willis Polk and is named in honor of San Francisco cable car pioneer Andrew Smith Hallidie. It has been referred to as the most architecturally important building in San Francisco, with the exterior balconies and fire escapes instantly recognizable. In 2010, these portions of the building were deemed unsafe, and a two-year restoration began. This was completed in 2013, with care taken to restore safety without altering the original exterior.
The building was the first example in San Francisco of a glass curtain wall over a steel frame, a system utilized today in nearly every new high-rise in the city.
