In a complex transformation, the Basel-based architecture firm Focketyn del Rio Studio has converted the main building of the city's former military barracks into a vibrant cultural and creative hub. Situated on the embankment of the Rhine, already a hotspot of Basel's almost Mediterranean-style nightlife, it offers some 32,000 square feet of work and project spaces, a spacious plaza, a theater hall, as well as a bar and restaurant.

This book documents the building's new architecture in detail and tells the story of Focketyn del Rio Studio, which won the competition for rebuilding the Kaserne Basel in 2013 only six months after it was established. Interviews, concise texts, photographs, as well as plans and drawings, provide insight into the evolution of the project, the history of the old barracks, and the complex process of their transformation. It also features the perspectives of the various participants and stakeholders in the undertaking. All Under One Roof also takes the example of what has been inaugurated as kHaus in the spring of 2022 to discuss key questions of the design and use of urban public spaces, topics of great importance for urbanists, architects, and public decision-makers far beyond Basel.
