Giles is a founding member of Assemble, a multi-disciplinary collective working across architecture, design and art. Founded in 2010 to undertake a single self-built project, Assemble has since delivered a diverse and award-winning body of work, while retaining a democratic and co-operative working method that enables built, social and research-based work at a variety of scales: both making things, and making things happen. Assemble won the Turner Prize in 2015.
Giles studied architecture at the University of Cambridge and the Royal College of Art. He has taught architecture at the University of Westminster and has lectured widely internationally. In 2016/17, Giles is co-leading the Design Think Tank New Knowledge with Anthony Engi-Meacock.
