This thesis examines the construction and potential future development of an electrical substation built in Berlin in the 1920s. The study is divided into four acts.

In Act I, the influence of traditional regional bricklaying techniques on the building's layout, performance, and aesthetic is explored. This includes an analysis of the skilled artisans who built the structure and how their craftsmanship shaped its dimensions and composition.

Act II presents a proposed intervention strategy by a contemporary architect. The architect introduces timber as a new material to complement the existing masonry and steel structure. A manual of removable bricks is created to ensure the integrity of the existing structure while allowing for the installation of the timber elements.

In Act III, contemporary artisans implement the architect's strategy through selective removal of bricks in the existing walls. This allows for the adaptation of the space to a range of programs while honoring the craftsmanship of the original tradespeople.

Finally, Act IV explores the feedback provided by outside visitors and its influence on further transformations and appropriations of the space. The thesis emphasizes the importance of understanding a building's history when proposing low-impact interventions by inhabitants without extensive construction training.

In summary, the case study of the 1920s power station in Berlin’s Tegel neighborhood highlights the importance of collaboration between architects, users, and craftspeople in the transformation and repair of old buildings. The integration of local craftspeople and their specialized skills ensures that the building is restored with care and attention to detail, preserving its unique features and cultural significance. This approach not only has economic and cultural benefits but also respects and honors the craftsmanship of the past while finding innovative solutions for the present and future. By following this sensitive roadmap, old buildings can be transformed and repurposed while maintaining their history and character.
