Exceptional Mansion – Prestigious Offices

A remarkable Beaux-Arts style mansion, built in 1916 for the Vaxelaire family and extended in 1928, the Hôtel Vaxelaire is an exceptional property located in the heart of Saint-Josse-ten-Noode, just steps from Place Madou, the European Quarter and Brussels’ inner ring road.

The building, whose front façade and roof are listed, elegantly combines architectural heritage with a contemporary extension (1989), offering spaces that are both prestigious and functional. The original reception rooms, carefully restored, have retained their outstanding features: a marble ceremonial staircase, reception rooms, decorative wrought ironwork, period parquet floors, original wood panelling and marble fireplaces.
A modern wing completes the ensemble, providing bright office floors arranged around a central glass roof.

Set back from Avenue de l’Astronomie, behind an ornate wrought-iron gate with motorised entrance, the property enjoys a rare architectural presence and a prestigious setting, while benefiting from excellent multimodal accessibility (Madou metro station, numerous public transport connections and immediate access to major road links).

The property offers approximately 3,255 m² over 7 levels, comprising approx. 2,065 m² of office space and approx. 1,190 m² of archives, technical rooms and communal areas. It is further complemented by a buildable plot located on Rue de l’Alliance, in a residential zone, offering additional development potential (subject to planning permission).
