Charles Tashima was born in New York City and has lived internationally until settling in London. He received his Bachelors in Liberal Arts at Wesleyan University in 1987 and his Masters in Architecture at Harvard University Graduate School of Design in 1991. Upon graduating with honours, he was recipient of the Thesis Prize for his final design project. In that year he was also awarded the prestigious Harvard University Kennedy Traveling Fellowship to study vernacular architecture and landscape for a one-year “grand tour” through Eastern Europe, Turkey, Greece and Italy.

Charles' engaging and collaborative approach comes from his extensive years of teaching. From 1993-1996 he was a design tutor with Marcel Meili and Markus Peter at the Eidgenössische Technische Hochschule (ETH) in Zürich. Following on, he taught at The Architectural Association in London as Unit Master from 1997 to 2006 and Academic Head from 2009-11. He has been a visiting critic, juror and external examiner at a number of schools internationally, including a Visiting Professorship at the École Polytechnique Fédérale de Lausanne (EPFL). 

He has worked in practices in the US, Switzerland and Germany before founding Charles Tashima Architecture in 1999.
