“…Moreover, several researchers have noted that building shape is strongly influenced by city planning regulations (e.g. Chau et al, 2007;Grierson and Khajehpour, 2002;Katsuragi and Watanabe, 2000;Kirita et al, 2007). This shows that building shape is determined by block shape and city planning regulations.…”

“…Chau et al (2007) analyzed the optimal building shape under building height regulatory restrictions. Moreover, several Japanese researchers examined the association between building shape and city planning regulations, such as floor area ratio (FAR) and slant plane restrictions (see online Appendix 1, Table A1), as can be seen in Katsuragi and Watanabe (2000), Kirita et al (2007), Aoki et al (2010), and Kawakami and Ohnishi (2013). Shpuza and Peponis (2008) measured the floorplate shape in two different ways and analyzed its influence on office layout.…”

Block restructuring has been strongly emphasized in Japan for renovating cities. However, little is known about the relation between block size and building shape. Moreover, the shape of buildings designed on a block after restructuring is unclear. In this study, the relation between block size and building shape is analyzed quantitatively, and a three-dimensional building shape is estimated by a model using an urban planning GIS data set of Tokyo. Results show the quantitative relation between block size and building shape, and the building shape image on the blocks. Higher buildings and buildings with a basement tend to be built in larger blocks, leading to efficient use of the maximum volume permitted in the block. In addition, the region composed by larger blocks can be spacious, because the range of building setback will be long in larger blocks. Designation of a high floor area ratio may induce integration and enlargement of blocks. Blocks are less likely to be partitioned in zones when a high floor area ratio is designated.
