History
Anshen + Allen was founded by Bob Anshen and Steve Allen in San Francisco in 1940. Their relationship began while they were studying at the University of Pennsylvania School of Architecture. Upon graduation, they both received a traveling fellowship that eventually led them to San Francisco in 1937.

Their first project was the Davies House, a 6,000-square-foot (560 m2) Tudor Gothic inspired mansion in Woodside, California, commissioned by Ralph K. Davies, a senior vice-president ofStandard Oil of California. The house was completed on November 30, 1941. After the end of World War II, the firm as a generalist practice developed gas station prototypes for Standard Oil,parking garages and interior naval architecture.

Joseph Eichler, a residential real estate developer, commissioned Anshen + Allen to build the initial Eichler homes in the California Modernist style beginning in 1950.The firm continued to build tract housing until 1962. In the late 1970s and early 1980s, under the leadership of Derek Parker, the firm was transformed into a modern international architectural practice as it is today. In the mid-2000s, Anshen + Allen adopted the use of Building Information Modeling(BIM). In 2007, Anshen + Allen participated in the development of Integrated Project Delivery by serving on the IPD Definition Task Group of the American Institute of Architects (AIA) California Council.

Anshen + Allen repurposed shipping containers as clinics for Containers 2 Clinics (C2C), a non-profit organization that provides access to healthcare for women and children in rural areas.

Today the firm specializes in sustainable designs for the healthcare and academic markets.
