It sure looks like it is either:
a. Designed by Frank Lloyd Wright
b. Designed by the Taliesin Fellowship
c. Designed by a follower of Wright
We are fortunate to have a book, The Sidewalk Companion to Santa Cruz Architecture , so duh...I looked it up.
It was designed by a San Francisco architect, Aaron Green. Mr. Green assisted Wright on many projects and was associate architect for the Marin County Civic Center.
Aaron Green 1917 -2001
Aaron Green was born in Corinth, Mississippi in 1917 and grew up in Florence, Alabama.
Aaron Green studied as an architect at Cooper Union in New York City, New York, which is where he was first introduced to the works of Frank Lloyd Wright. Green first met Wright when asking the renowned architect to design a house for Stanley Rosenbaum. Green was invited by Wright to join Taliesin as an apprentice in the early 1940s, from which point the two maintained a close friendship. Green enlisted in the Air Force during World War II, serving as a bombardier in the Pacific theater.
After the war, Green moved to Los Angeles and worked as an interior designer with industrial designer, Raymond Loewy. During this time, he married and began a family. In 1951, Green moved to San Francisco and founded Aaron G. Green Associates, Inc., an architectural practice dedicated to service-oriented design. In this organization, Green acted as Wright's West Coast representative.
Green participated in forty of Wright's projects. At the time of Wright's death in 1959, the Marin County Civic Center was uncompleted, and Green saw the project through to completion.In 1968, Green became a member of the College of Fellows, American Institute of Architects. He taught as a lecturer and critic at Stanford University's department of architecture for fifteen years. In 2001, Green became the first recipient of the Frank Lloyd Wright Foundation's Gold Medal.
Green died on June 5th of 2001 at the age of 84.
