The Circulation Tank 2 (Umlauftank 2 1967–1974) is a heritage protected Berlin landmark built by German architect Ludwig Leo (1924–2012). The iconic building is a laboratory—a testing ground for flow experiments, for modes of architectural expression and now since its restoration for how to deal with recent monuments. The utopian planning approach of the Umlauftank 2 constitutes a synthesis of form and function, of creative collaboration and minimalist structure, of scientific research and expressive appearance. The book design represents the architecture’s spirit. It aims at communicating the social relevance of heritage protection to a broader public. Re-interpreting design elements from the original building, the book brings together historic and poetic, documentary and critical perspectives on a rare architecture design approach.
The book design was awarded with DAM Architectural Book Award 2020 and on the shortlist of the most beautiful German books 2020
