Prefecture (Figure 1). The former Kakogawa Library was designated as an important cultural asset for landscape formation by the Hyogo Prefecture in 2008 and was used as a public library until 2021.

As part of their research project, eight third-year students from the Architecture Department's "FabLab Studio Toban" conducted a survey using a 3D laser scanner and recorded the precise shape of the former Kakogawa Library. This report summarises the process from the surveying to the creation of a 3D printed model and discusses the results achieved.
