Alongside his practice - Office for Cities -developing strategic research projects and urban development schemes, his writing aims to fuel the social, political and cultural debate on built environment issues. Recently, Flavien curated and animated The Bedford Tapes - a day of public debate gathering for the first time a bench of emerging engaged protagonists questioning through their practice the agency of the architects and its impact on societies and territories. Flavien taught at the Architectural Association - Oracles for Europe Unit 13 - and is a regular guest critic at the Royal College of Arts, London Metropolitan University and ETH Zurich.
