Mill Valley home revealed to be unheralded work of famed architect Joseph Allen Stein

A MODEST HOUSE in Mill Valley was honored Tuesday as a “lost work” of renowned architect Joseph Allen Stein, who fled the Bay Area to Mexico with his family in 1950 before it was built.

The mid-century modern — an efficient glass-dominated design that housed a family of five in just 1,100-square feet — was commissioned by William Hogan, former long-time San Francisco Chronicle book editor, and his wife, Phyllis, a teacher and former journalist.
