Built as a necktie, belt, and suspender factory shortly after the 1906 earthquake, the 20-foot wide Heineman Building is a registered landmark. At one time the tallest structure on the block, the “little building that could” is now dwarfed by its neighbors. But thanks to the massive Crown Zellerbach across the street, this gem of old San Francisco can now admire its own ten-story reflection in polished glass.
