Japanese architect Sou Fujimoto and Belgian studio AWAA teamed up to design this mixed-use tower complex on the outskirts of Brussels, which will comprise a scooped roof and facade covered in tree-lined balconies.
Sou Fujimoto and AWAA won a competition launched by property developer Unibra and construction company Thomas and Piron, to design the Delta Tower in the Auderghem municipality.
