Johan graduated with high distinction from La Cambre-Horta in Brussels, spending part of his studies on exchange at Keio University in Tokyo. He later joined the office of Junya Ishigami, where his Franco-Japanese sensibility took root: a deep attention to materiality and spatial precision. After several years running his own practice in Brussels as a DPLG-qualified architect, he joined Hamonic+Masson & Associés in 2026.
