Bureau de Change is an award winning architecture practice founded by architects 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.
