A Use of Form-Based Code for Volumetric Morphology of High-density Cities

This paper presents the experimental use of Form-Based Code (FBC), an alternative approach to urban planning and regulation, for volumetric morphology towards more flexible and predictable development in high-density cities. Quantitative analysis of the Tsim Sha Tsui (TST) area of Hong Kong results in a workflow for using FBC in high-density contexts; combining transect matrix redefining, the integration of multiple variables, and parametric modelling. Findings indicate that a newly-defined transect matrix with multifarious types and subtypes enables the extension of the FBC study to encompass high-density conditions. Secondly, that FBC has the capacity for the assembly of multi-level regulations more suitable for volumetric urban forms. Thirdly, that the parametric regulation method of FBC can visualize and enumerate scenarios that conventional paper-based regulation cannot. The findings also suggest increasing the awareness of urban forms, rather than rigid land-use concerns, can be a critical influence when designers are pursuing sustainable communities within crowded contexts.
