New regulations in UK and Europe force manufacturers to establish sustainable efforts into their manufacturing process. Me and my team are exploring the possibility to transfor one of largest sofa manufacturers in UK to be more sutainable.

 









Sofa design has many sustainability problems. 



All this time, sofas have been designed for one-time use, and the value of used sofas is almost nothing, so the majority of people don't want to buy second-hand. Beyond that, many sofas end up in landfills, making disposal very problematic for user






Disrupting unsustainable manufacturing process.


Our solution introduces a subscription business model that revolutionizes manufacturing processes and redefines the relationship between users and furniture, dramatically improving circularity rates


OWNE: A systems, business and product design approach to a truly sustainable, circular sofa.






Designed for disassembly, repair, and reused.
We designed a sofa concept suitable for a subscription business model. The sofa is designed for disassembly, making it easier to deliver and save space in logistics, while enabling users to repair it themselves or return it to the shop for servicing. 

The subscription model allows the company to reclaim materials when users no longer need the sofa, creating a circular economy. We identified the wood frame as the most valuable component for extending the sofa's lifespan—by reusing frames and replacing upholstery and fabric, the company can offer refreshed products while minimizing waste

       
Scale model build to explore the structure design and the joint mechanism to make it easy to repair and reuse



A modular frame that can be disassembled and upholstery that can be compactly stored









Engineered for measurable sustainability impact


Beyond conceptual design and storytelling, we engineered a solution with quantifiable environmental performance. Our proposal demonstrates technical rigor through detailed metrics: material circularity index, carbon footprint calculations, and full lifecycle impact assessment
