Portland Works is a Grade II* Listed integrated cutlery factory. A hundred years ago, it was the birthplace of stainless steel manufacturing. Today it is a hub of craft and innovation, home to a community of diverse and thriving businesses including metalworkers, engravers, artists, wood workers and musicians. This project was initiated when the landlord submitted a Planning Application for ‘Change of Use’: he proposed to close the Works and convert it into bedsit flats. Tenants, activists and local people worked first to oppose this, and then, to propose alternatives. The campaign started to stop Portland Works being wiped out, rather than preserving it, and in the process hatched a plan for how it might evolve in the future. This publication draws together and documents the research carried out by a number of people wishing to consider what these alternatives might be and how they might be achieved. The ‘Portland Works Industrial and Provident Society (IPS)’ launched Sheffield’s first community share issue for the purchase and refurbishment of the Works. In order to get to this point we have explored options, researched precedents, constituted as an IPS, produced a detailed business plan, developed networks with cultural and educational organisations, changed local planning policy and galvanised local and national support. We have also got to know each other much better; there have been thousands of hours volunteered, funds raised, skills shared and ideas debated. This activist research has taken numerous forms, including exhibitions, conference papers, audits, case studies, student projects, workshops, and films. It has been carried out collaboratively, led by our shared understanding of the project as it developed, with no predetermined outcome. The main aim of this research was the development and implementation of a framework for collective production and action where engaged scholarship, community activism and community economic development converged to Save Portland Works from speculative redevelopment. This book is a deliberately eclectic collection of fragments, traces and snapshots of a civic action and a research process that worked together to envision and implement equitable and sustainable community economic development for one Sheffield’s most significant pieces of heritage: Portland Works as spatial conduit and locus of manufacturing and craft, cultural production and civic engagement. We hope that it will be useful for others wishing to embark on similar processes to hear about what we did; our successes, our mistakes and explorations. Cristina Cerulli and Julia Udall
