Award-Winning Architecture Studio | London
Bureau de Change is an award winning architecture practice founded by Katerina Dionysopoulou and Billy Mavropoulos. Its work is a direct product of the founders' upbringing, passions and experiences - combining the pragmatism and formality of their architectural training with a desire to bring a sense of theatre, playfulness and innovation to the design of spaces, products and environments. The result is a studio where rigorous thinking and analysis are brought to life through prototyping, testing and making. Within the last four years Bureau de Change has won numerous awards from the FX Breakthrough Talent of the year 2016 to the Sunday Times Architect of the Year award 2019 and was most recently shortlisted for the RIBA Awards 2020. The studio’s work was selected as part of the 250th Royal Academy Summer Exhibition. Bartlett graduate Katerina Dionysopoulou trained at Foster+Partners before joining Heatherwick Studio. During this time she led the team designing the UK Pavilion at the Shanghai Expo, winning the coveted Lubetkin Prize. She later worked alongside Danny Boyle as the project leader for the iconic Olympic Cauldron for London 2012. Billy Mavropoulos studied at the Royal College of Art and trained at Foster+Partners. Prior to founding Bureau de Change, Billy worked as an independent design consultant on projects for the Tate Modern, Tate Britain and Selfridges. In 2010 he featured in Wallpaper magazine’s next generation issue as a designer who will change the face of design within the next 30 years. Billy and Katerina currently teach UG4 at the Bartlett School of Architecture.
