Eco-Bau Zimmermann GmbH

Freiburg

About the company

Founded in 2008 by Clara Zimmermann, a master carpenter with additional qualifications in sustainable building design, Eco-Bau began as a specialized contractor focusing solely on ecological construction methods. The 2010 German energy transition policy created expanded opportunities, allowing the company to grow from its original 8-person team to a mid-sized operation. In 2016, Zimmermann secured significant investment from a green-focused venture capital firm, enabling further expansion while maintaining her position as majority owner and managing director.

Values

Eco-Bau Zimmermann is committed to advancing sustainable construction practices while proving their economic viability. We believe building with ecological materials and energy-efficient designs represents not just environmental responsibility but smart business for the future. The company maintains strict safety protocols, especially around wood processing equipment and height work, with formal training requirements exceeding industry minimums. Every Monday begins with a team safety circle, and the company's accident rate stands at roughly half the industry average. Clara Zimmermann personally conducts quarterly safety audits of all operations.

Workshop

Eco-Bau operates from a converted former textile factory in Freiburg that has been extensively retrofitted to passive house standards, serving as both company headquarters and demonstration project. The 1,800m² facility features a purpose-built timber construction workshop with advanced dust collection systems and natural daylighting. A materials library showcases ecological building products for client consultations. The workshop is organized according to lean manufacturing principles with clearly marked workflow zones. The outdoor yard contains a rainwater collection system that supplies the facility's non-potable water needs. Solar panels on the roof generate approximately 60% of the building's energy requirements.
