Darcy Arnold-Jones

Darcy Arnold-Jones is an Architect and Circular Economy Lead at Marks Barfield Architects, and a Circularity Consultant at Reusefully. She is also a member of the Circular Do-Tank, The Edge and ACAN.

Alongside her architectural practice, Darcy leads Marks Barfield Architects’ circular economy strategy, driving research and implementation of regenerative and resource-conscious design principles. She leads the practice’s work on whole life carbon assessments, material reuse audits and circular design strategies, while developing innovative tools, including an in-house donor–recipient model, to facilitate material reuse across projects. 

Working closely with demolition contractors, industry specialists and project teams, Darcy champions a transition from demolition to urban mining, helping to unlock the value of existing buildings as material resources. Her work spans material-specific reuse strategies, the development of second-hand construction material networks, and the wider systems change needed to embed circularity across the built environment.

In her role as a Circularity Consultant at Reusefully, Darcy advises clients and organisations on practical approaches to implementing circular economy principles within the construction industry. Through her work in practice, consultancy and industry advocacy, she is helping to accelerate the adoption of circular construction and low-carbon, regenerative approaches to the built environment.
