From Modernism to Regeneration - The Transformation of ING Marnix HQ
The ING Marnix headquarters by A2M – Moreno Architecture & Associés transforms Gordon Bunshaft’s 1960s Banque Lambert iconic listed building into a benchmark for regenerative urban retrofit. The 54,058 m² office underwent a comprehensive upgrade that reconciles heritage fidelity with rigorous environmental performance through a clear manifesto: design with climate, design with nature, design with people. The project achieved BREEAM Outstanding and WELL Platinum certifications while meeting carbon-neutrality targets.
Rather than starting from scratch, the intervention builds on Bunshaft’s original principles - transparency, wellbeing, art, and innovation. The former basement was opened into a 6,000 m² super-duplex connecting to landscaped patio and sculpture garden and activating previously residual space, integrating coworking areas, an art gallery, hospitality, catering experiences, and lounge spaces accessible to all users. It acts as a climatic urban cooling device. A vertical void now cuts through every floor, bringing daylight, while acting as a spatial spine and social catalyst. Internal connections were redefined to unify the two volumes and strengthen openness toward the public realm.
Architecturally, the building retains its original prefabricated concrete exoskeleton façade, an innovation from 1964 that liberates interior floor plates. Today, this structure is reinterpreted as an effective solar protection system, contributing to thermal comfort in a future climate scenario projected for Brussels at +4°C. A new high-performance envelope - triple glazing, thermal-bridge mitigation, and airtightness around 0.6 ACH - reduces operational energy by approximately 84% and carbon emissions by 75%. Biogenic insulation, material reuse, and circular strategies reduce embodied impact, while annual energy savings approaching several million euros confirm the economic viability of deep renovation.
Internally, daylighting, flexible workspaces aligned with New Ways of Working, passive climate strategies, and biophilic design promote wellbeing and adaptability.
The result is a structure that breathes again, demonstrating that regenerating heritage can become a powerful act of contemporary architectural creation.
