Welton Becket’s most #iconic Bay Area structure may well be the Kaiser Center, a 25-story, gently curved office complex overlooking Lake Merritt in Oakland. Becket built the Center—then the tallest office building West of Chicago—for $45 million in #1960 (same year as Bethlehem Steel!) as the center for #industrialist Henry J. Kaiser’s #aluminum, #shipbuilding, #automobile, #hospital, and #Hawaiian real estate empire. (1) Becket’s #1958 model for the site, showing the influential rooftop garden above the parking garage (Calisphere). (2) The Rooftop, seen in a mid-#1960s postcard (Playle’s). (3) Part of the original @holynamesuniv #campus, constructed in #1878, was #demolished in #1957 to make way for the center. The @bostonglobe captured its topple. (4) The #topping out in #1958, showing the Center’s preeminence over the rest of the Oakland skyline (@sfchronicle). (5) A blueprint of a typical floor and the remarkably complicated lobby level, which included shops, a pool, medical space, and a pedestrian bridge to the parking lots. (6) Joseph Magnin’s dress shops, for whom Becket had also designed a @stonestowngalleria branch, opened up in the lobby (both @archrecordmag, #1960). (7) The #1960 @aianational convention included an invitation from Kaiser to visit the new landmark. (8) The size of building necessitated all sorts of #bureaucratic innovations, like “magnetic memory” paper conveyers (Recordlifts) that distributed mail across the building (@archrecordmag, #1960). (9) Kaiser had a large #architectural footprint in the Bay. Their employee hospitals, which eventually grew into @kaiserpermanente, were scattered throughout. Here’s their #1954 SF campus, by frequent Kaiser collaborator, Portland architect George Wolff, advertising Ariston Windows (@archrecordmag, #1954). (10) Sutroid mainstay John Carl Warnecke designed an 85-acre Kaiser research complex in Pleasanton’s Amador Valley, completed in #1973. Seen here is the #jutting front of the administration building, where Kaiser worked on new #aluminum coloration processes (@archrecordmag, #1973). Today, the Kaiser Center houses @bankofamerica, @aecom, @sfbayarearapidtransit, and the @kaiserfamilyfoundation.
