The Berchmanianum in Nijmegen is not your typical project brief. A monumental Jesuit seminary built in 1904, the building has served as a spiritual retreat, an academic conference centre, and now as a thoughtfully repurposed workspace destination. When Werk Solutions was brought in to rethink the interior furnishing strategy, the challenge was clear: honour the heritage of the space while ensuring every material decision aligned with circular design principles. The result is one of our most technically demanding and rewarding projects to date.

Why Should Circular Furniture Design Start with Reuse?
Before a single new piece of furniture was specified, our team conducted a full inventory audit of what already existed within the building. This reuse-first approach is central to circular methodology. Rather than treating the existing stock as an obstacle to clear, we identified which pieces could be refurbished, reupholstered, or redeployed in new zones. Solid timber pieces that had been stored in the building's lower levels were stripped, re-treated with water-based finishes, and returned to active use in the reading rooms and quiet collaboration areas.
For the pieces that could not be recovered, we worked exclusively with manufacturers who operate closed-loop take-back programmes. This means that at the end of their service life, components are returned to the manufacturer for disassembly and reintegration into new production — not landfill. Material passports were issued for every new item brought into the building, documenting origin, composition, and the process for eventual recovery. Through furniture for modern classrooms, we help schools transform their spaces.
How Do You Install Modern Furniture in Heritage Buildings?
Working within a listed historic building places strict limitations on what can be fixed, drilled, or altered. Rather than treating this as a constraint, we used it as a design driver. All furniture systems were specified to be entirely freestanding, using weight, balance, and modular connectivity instead of wall fixings. This approach has an added circular benefit: nothing is permanently bonded or attached, meaning the entire interior can be reconfigured or removed without leaving a trace on the original fabric of the building.
Key decisions made during the Berchmanianum project:
- 100% of legacy furniture audited before any new procurement was approved
- Refurbished items accounted for 34% of the final furniture inventory by unit count
- All new textiles specified from certified recycled or natural fibre sources
- Zero permanent fixings used throughout the entire installation
- Material passports issued for every product introduced to the space
How Do You Measure the Environmental Impact of Circular Design?
Sustainability claims without data are just marketing. For the Berchmanianum, we tracked embodied carbon across the full procurement and installation process, comparing our circular approach against a conventional equivalent specification. The results demonstrated a 41% reduction in embodied carbon compared to a standard new-furniture approach. Waste generated during installation was under 2% by weight, with all packaging returned to suppliers under pre-agreed take-back arrangements.
The Berchmanianum stands as proof that circular principles and heritage sensitivity are not in tension — they are, in fact, deeply compatible. Both ask the same fundamental question: how do we preserve value across time? If you are working on a heritage building or a project with ambitious sustainability targets, we would welcome the conversation.
