Urban Grids: Projective Density

The process of urbanization, to a large extent, can be seen as a gradual way of densification. Urban density, as a crucial index in urban design and analysis, has too often been interpreted and implemented as a statistical factor and design rule. However, the nature of density embodies a great potential to stage the urban transformation within which the design strategy can be informed.

It is based on this consideration, this research is trying to look at urban density through a different lens to reveal the potential of urban density as a projective urban rule. The priority of this research is focus on the factor of FAR (Floor Area Ratio) in relation with both the city's block morphology and building typology. As a progressive method to visualize these relations, each of the morphological and typological relations has to be defined through a statistic manner similar to the idea of FAR. Therefore, the morphological relation is seen through the ratio between the street width and the block proportion, which not only identifies the geometrical nature of the block but also demonstrates the spatial relation in between them. Similarly, the typological relation is recognized through the ratio between the building frontage (width) and the length of the block edge on which the building frontage is located. This factor shows the dimensional relation between building width/depth and the block proportion. When all the morphological and typological ratios are made in comparison with the factor of FAR, the seemingly invisible relations between the urban density and the formal strategy of city blocks and buildings are explicated.
