The Crown Zellerbach Building was
the first glass skyscraper built in San
Francisco when finished in 1959.
Wonderful floor-to-ceiling green
tinted glass and beautiful details can
be seen all over it.The most striking
features though are the sunken garden
at the ground level plaza, the elegant
glass pavilion lobby and finally the
offset opaque service core facing
Market Street as a wonderful
counterbalance to the glass office
Thanks for your help.
