Historical Identity

Banque Brunner — and the first concrete dome of Brussels.

Built around 1860 and long known as Banque Brunner, the property embodies the restrained grandeur of Brussels' 19th-century institutional architecture. Around 1900, architect Léon Govaerts added a remarkable banking hall topped by a concrete dome — recognised as the city's first — creating a rare dialogue between classical residence, civic memory, and monumental light. Recently restored with care, the building combines heritage character with modern comfort.
