A remarkable architectural transformation has taken place in Tübingen, Germany, where architects KO/OK Architektur have successfully converted a historic barn dating back to 1806 into a contemporary residential building. The project, known as Doppelscheune, represents a thoughtful approach to adaptive reuse in the historic center of Derendingen.
The 190-square-meter residential conversion was completed in 2024 under the leadership of Jan Keinath and Fabian Onneken from KO/OK Architektur. The project demonstrates how historical agricultural buildings can be given new life while preserving their cultural significance and architectural heritage.
Located in the southwest of Tübingen, the converted barn sits prominently beside the road, surrounded by other historic structures including the village church, an old schoolhouse, a bakehouse, and former agricultural buildings. This setting emphasizes the project's role in the ongoing transformation of Derendingen's historic center, which is experiencing a period of renovation, repurposing, and selective densification.
The architectural team worked closely with specialists to ensure both structural integrity and environmental sustainability. Felix Mindner Tragwerksplanung provided structural engineering services, while Verena Klar, an independent architect and energy consultant from Mähringen, handled environmental sustainability consulting.
The project utilized high-quality materials and systems from renowned manufacturers including JUNG, KEIM, FSB Franz Schneider Brakel, Creaton, Hessler, Ifö Electric, and Mosa. These selections reflect the architects' commitment to combining traditional building methods with modern performance standards.
Photographer Sebastian Schels documented the completed transformation, capturing how the historic barn's character has been preserved while adapting it for contemporary residential use. The project represents a successful example of how historic buildings can be sensitively adapted to meet modern living requirements while maintaining their connection to the local architectural heritage.
