San Francisco’s North Beach library, which AN reported on today is finally under construction after more than two years of delays, is the last of more than 20 city library branches to be repaired or rebuilt thanks to a $105 million bond measure that SF voters passed in 2000 called the Branch Library Improvement Program (with the unfortunate acronym, BLIP). The measure has spurred innovation from several of the city’s top firms, and we couldn’t resist sharing more of their work in the slideshow below. Only two remain: North Beach and the Bayview Branch Library, designed by THA Architecture in collaboration with Karin Payson A+D, which is scheduled to open later this month.
