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 — described as the city's first concrete dome — creating a rare dialogue between classical residence, civic memory, and monumental light. Recently restored with care, the building combines heritage character with modern comfort.

Densification Potential

A permitted vertical extension of two additional floors.

The asset benefits from an approved planning context for a vertical extension of approximately 420 sqm — the addition of two further floors above the existing volume. This is consistent with the broader densification framework for the surrounding block, which actively supports the addition of upper floors on existing structures along the corridor.

Subject to all applicable legal, planning, technical, and heritage approvals. Full permit documentation and surrounding-block redevelopment masterplan available upon request.
