Classified Private Mansion, Ideal for an Institutional Headquarters, Embassy, Private Club, or Major Cultural Project.
Between the hushed murmur of the European institutions and the verdant breath of the Brussels Park rises, opposite the Royal Palace, a residence where time still bows to elegance. Built around 1860, this listed mansion, long known as the “Banque Brunner,” embodies the very essence of Brussels prestige, a perfect dialogue between memory and modernity, between stone and light.
Beneath its noble mantle of blue stone, the façade unfolds like a classical score across three levels of grace. Ornate balustrades, sculpted frames, and a central balcony answer one another like notes in a harmonious architectural theme. At the top, a delicately decorated entablature ends in a stone balustrade, a gesture of reverence to the beauty of a bygone era. Inside, the house reveals the discreet grandeur of the great 19th-century residences. The carriage entrance opens onto a sequence of adjoining salons where silence still seems alive with the rustle of fabrics and the whispers of past receptions. The grand staircase leads to the state rooms on the first floor, while the upper levels offer the serene intimacy of private apartments.
Around 1900, architect Léon Govaerts gave this jewel an audacious extension : a banking hall topped with Brussels’ first concrete dome. Beneath this vault of stone and light, a marble staircase unfolds its pure lines, magnifying the solemnity of the setting and lending the whole an exceptional institutional majesty.
Recently restored with exemplary care, the building now combines respect for heritage with the precision of modern comfort. Its remarkably generous volumes extend over more than 2000 m2 of built space on a 628 m2 plot. The property totals 2,066 m², including a 600 m² basement that still houses the original bank vaults. The front section comprises a ground floor of 233 m2, a first floor of 233 m2, a second floor of 230 m2, and a third floor of 210 m2. It is worth noting that a vertical extension of two additional floors, totaling 420 m2, could be envisaged. The central space beneath the majestic dome offers 210 m2of unparalleled character. The rear section features a ground floor of 185 m2, a mezzanine of 33 m2, and a first floor of 132 m2.
This building, located on one of the capital’s most emblematic thoroughfares, No. 78, Rue de la Loi, stands as a true symbol of power and diplomacy, offering an unrivalled strategic position near European institutions, public transport, parking facilities, and direct access to the historic centre.
More than a property, it is a living, breathing piece of history, a testament to elegance and influence, ready to embrace a new destiny : an institutional headquarters, an embassy, a private club, or a major cultural venture.
Beneath the dome of light, every stone still seems to whisper the legacy of a century of excellence. Here, prestige is not merely admired… it is deeply breathed.
