Steven Holl is globally renowned for monumental works that specifically invoke light, color and porosity in both programmatic and aesthetic ways. Holl can also be thought of as an artist’s architect—his firm has done work for many arts institutions, he methodically sketches his projects in watercolors, and his style is heavily influenced by art practice and theory. He’s also very interested in the phenomenology of architecture—how it’s sensed by humans, and its impact on our existence. We spoke in a totally unremarkable conference room at the Salk Institute in La Jolla, California, the day before Holl was scheduled to give a keynote presentation for the Academy of Neuroscience for Architecture’s conference.
