I am writing an academic essay for an Architectural Theory course on the concept of nonsolution as developed by Gabu Heindl and Drehli Robnik in their book Nonsolution: Disputed Closures in the Politics of Architecture. I will provide excerpts or the full text of the book, which should be treated as the primary theoretical framework for the essay. The case study is The Waterhouse at South Bund (also known as The Vertical Lane House) by Neri & Hu in Shanghai. My focus is specifically on the architects’ decision to leave parts of the existing military building intentionally unresolved, including: the original façade, existing staircases, selected interior finishes and surfaces. I want to analyze these design decisions through the lens of Heindl and Robnik’s theory of nonsolution, rather than through conventional concepts such as restoration, preservation, or adaptive reuse alone. The essay should investigate how the project deliberately resists complete resolution, repair, or closure, and how the retention of traces, imperfections, and historical layers can be understood as a form of architectural nonsolution. I will also provide: The writing requirements and formatting rules for the assignment. Relevant excerpts from Nonsolution: Disputed Closures in the Politics of Architecture. Any additional references that must be incorporated. Before writing, carefully analyze the theoretical material and extract the concepts that are most relevant to the project. Build the argument primarily from Heindl and Robnik’s framework and only use other references when they directly support the central discussion. When developing the essay: Establish a clear thesis. Connect theoretical concepts directly to architectural elements of the project. Avoid generic descriptions of adaptive reuse. Focus on how the retained façade, staircases, and unfinished surfaces function as architectural nonsolutions. Support all claims with evidence from the provided theoretical texts. Maintain an academic architectural-theory tone.
