More InformationIn the Wiegand Quarter in Merseburg, close to the city centre and situated directly by the River Saale, Hall 5 – built in 1936 – stands as a typical example of Central German industrial architecture in the chemical and mechanical engineering sectors. The site tells the story of 130 years of family-run industrial heritage: The Wilhelm Wiegand engineering works manufactured multi-stage evaporators and jet pumps, exporting over 4,000 units worldwide; Wilhelm Wiegand held 25 patents. Following its closure in 1994, the site gradually lost its industrial use – most recently, the hall served as an unheated parking area for motorhomes. The revenue generated merely covers operating costs and minimal maintenance; making it impossible to finance a structural and energy-efficiency refurbishment. Merseburg is thus representative of many post-industrial medium-sized towns in eastern Germany: the town has lost around 30 per cent of its population since its peak, the average age is 47.9 years, and there is a lack of a robust cultural and creative infrastructure. The aim of the project is to carry out structural and energy-efficiency refurbishment of the vacant hall by September 2028 and to develop it into a climate-positive ‘third place’ that combines re-use construction, open workshops and community-led building into an operational model for sustainable neighbourhood development.
The project aims to achieve three closely interlinked objectives:
Firstly, the historic existing structure of Hall 5 will be upgraded in terms of energy efficiency and functionality so that its long-term operation can be resource-efficient and largely powered by renewable energy. Photovoltaic panels, a heat pump, roof insulation and the continued use of the existing building fabric form the structural basis for this.
Secondly, a sustainable infrastructure is being created for open workshops, communal repair initiatives and the reuse of materials. The communal kitchen complements this infrastructure as a shared space for self-sufficiency, thereby supporting collaborative work, building and design activities within the hall.
Thirdly, users, association members and participating partners are involved in selected aspects of the structural and functional development. Collaborative construction and fitting-out initiatives enable direct participation in the creation of the space. Planning, implementation and experiences are documented in a transparent manner and prepared in such a way that they can be utilised for similar projects.
