When you walk across the STUMMER grounds in Bischofshofen, you immediately sense that something is happening here. The first major expansion began in 2019 with the groundbreaking ceremony for the new production hall 4, and now the next big development step is underway. Following the comprehensive renovation of the existing halls, the construction of new painting, grinding, and washing halls, and the complete switch to renewable energy sources, the project is now continuing—right next door.

The new assembly hall will become the heart of chassis preparation and the so-called “ wedding” between the body and the truck. It not only creates space for four preparation areas and a separate assembly area for prototype construction, but also a parking space for customer deliveries. Overall, the factory premises are growing by an impressive 7,500 m² – providing everything that modern vehicle production needs.

Logistics will also be simplified: all transfer trips to the previous interim storage facility will be eliminated in the future. Chassis deliveries by car transporter and superstructures from the ZOELLER plant in Poland will arrive directly at the new site. Around 85 new truck parking spaces, dedicated access roads, a weighbridge, charging stations with superchargers, and a parking management system that is directly linked to production planning ensure smooth processes and minimal maneuvering.

Special attention is being paid to noise protection and good neighborliness. STUMMER places great importance on minimizing the impact on local residents—both during the construction phase and later during operation. Solutions were developed during the planning phase to minimize noise emissions and harmoniously integrate the site into the existing environment.

STUMMER is also making progress in terms of energy: with the expansion of its photovoltaic system and a 200 kWh battery storage unit, the company will be around 90% energy self-sufficient in the future. Additionally, an air heat pump will be used for the first time to heat the industrial floor—another step toward sustainable production.

The project was planned in an open, transparent process together with the residents of Bischofshofen—and met with broad approval. Construction is scheduled to begin in October 2025 and be completed in May 2026.

With the new hall, STUMMER is not only strengthening its location in Bischofshofen, but also its function as an innovation driver in municipal vehicle construction – more efficient, more sustainable, and neighborly in the best sense of the word.
