Description

ZERO. is a future-oriented office building that courageously and ingeniously breaks the mould of conventional construction and, as part of the IBA’27 in Stuttgart, presents itself as a built example for the urgently needed sustainable building transition. Choosing a modular timber construction as an innovative, resource-efficient and circular building method was a key element of our holistic project development. As the keystone of the site, ZERO. completes the transformation of a former industrial area into a mixed-use quarter and strengthens the campus-like character and local community. The building combines innovation and sustainability in both construction and technology, with a strong focus on collaboration and community. Its programme brings together office areas, conference zones, a restaurant and a fitness studio to form a socially connected shared space on the ground floor. The modular timber architecture with a flexible ring-shaped structure enables adaptable office layouts. Each office loop offers high flexibility, supports communication, and creates visual connections across a central courtyard. Serial prefabrication of timber modules reduces CO₂ emissions, construction time and waste. Developed in collaboration with Transsolar, the smart-tech energy concept integrates passive strategies with regenerative, low-maintenance systems to enable near climate-neutral operation. ZERO. presents a vision of climate-responsive architecture shaped by responsible environmental stewardship.
