An emblematic monument from 1970s in Brussels, the building of the former Royale Belge served as the headquarters of AXA Belgium until 2017, but is completely empty today. A reconversion project is now being rolled out for this magnificent and immense monofunctional building with its bronze-tinted glass and weathering steel frame, surrounded by a green estate spanning some ten hectares. This is a mixed project that will integrate a wide range of functions with due respect for the architectural heritage.
