Addressing the multifaceted challenges of globalization, urbanization, and climate change, urban-rural development urgently requires transformation, with innovation as the key driving force. This study explores the potential of lighthouse projects as critical mechanisms for driving this transformation, using Germany’s International Building Exhibition (Internationale Bauausstellungen, IBA) demonstration projects as examples to investigate how they catalyze urban development reform. The IBA, as an informal urban planning tool characterized by vision-oriented planning and innovative experimentation, promotes urban transformation through its experimental projects. This research focuses on analyzing the Ossietzky-Hof case within the IBA Thüringen (2012-2023), examining how it facilitates transformation as an IBA demonstration project by investigating its implementation’s key operational methods and analyzing the underlying procedures, operational mechanisms, and organizational forms. The Ossietzky-Hof case, a demonstration project of IBA Thüringen, explores how to renovate old building complexes using resource awareness and energy conservation principles under the IBA Thüringen “StadtLand” theme, aiming to achieve climate protection and adaptation. This study adopts a case study approach, analyzing the background, objectives, implementation methods, and outcomes of the Ossietzky-Hof case. Supplemented by a literature review, it analyzes the innovations embodied in the case across multiple dimensions, including procedures, architectural design, energy strategies, interdisciplinary integration, and operational models. This research aims to reveal the operational mechanisms of the Ossietzky-Hof demonstration project, providing new possible paths and inspirations for the dilemmas of urban-rural development.
