Potential and Limits of Pointclouds as an Architectural Design Tool for Small Sized Historic Monuments Through the Case Study of Modernist Atelier House of Carl and Margrit Roesch in Diessenhofen, Switzerland
摘要
While usually used for large scale monuments such as cathedrals, the technology of pointclouds was applied on the rather small sized atelier of Carl Roesch (1884–1979) and Margrit Roesch-Tanner (1880–1969) in 2024 by Graf Roesch Architekten in order to obtain detailed information on the structure for a potential intervention that could adapt the complex to current housing standards. The modernist atelier of Carl Roesch, built in 1930/1932, was listed in 1986 and became a historic monument of the canton Thurgau in Switzerland with a revision in 2011. The paper describes the development of a digital work method used by architects: From 3D scanning on-site, digitally assembling the individual scans to processing the data so that it becomes understandable and readable. With these new digital methods, the threshold between reality and virtuality, walkable spaces and digital work surfaces was explored through animations, visualizations, and models. The paper discusses the potentials and limits of applying the laser scanning technology on a small scale monument in order to plan more reliably and economically potential interventions for the site in the future.
