The Europa building is situated on the former site of the partially demolished and renovated Bloc A of the Résidence Palace, a complex of luxurious apartment blocks. Its exterior combines the listed Art Deco facade of the original 1920s building with the contemporary design of the architect Philippe Samyn. The building is linked via two skyways and a service tunnel to the adjacent Justus Lipsius building, which provides for additional office space, meeting rooms and press facilities.
