Carton123 is an architecture office founded in 2013 by Joost Raes and Els Van Meerbeek, both trained as engineer-architects at KU Leuven. After gaining experience at renowned practices such as Flores & Prats, WIT and De Smet Vermeulen, they started their own studio in Brussels. Over the years, the team has grown to six, with Jordy Van Osselaer (KUL Gent, 2013), Sara De Sterck (KU Leuven, 2019), Pauline Vermeulen (KUL Gent, 2020) and Inigo Custers (UGent, 2023) joining the practice.
