An interactive design tool for urban planning using the size of the living space as unit of measurement

Abstract

In urban planning, one of the common units of measurement for population density is the amount of households per hectare. However, the actual size of the households is seldom considered, neither in 2D nor in 3D. This thesis proposes a method to calculate the average size of the households from existing urban areas based on available open data and to use it as a design parameter for new urban developments. The proposed unit of measurement is comprehensive of outdoor and indoor spaces, the latter comprising both residential and non-residential space. As a test case, the Haven-Stad project in Amsterdam was chosen, specifically its second phase, Sloterdijk One, envisioned by the municipality of Amsterdam to host 11220 households and 7480 working places by 2040. The sizes of typical households, as well as a series of other KPI’s (Key Performance Indicators) were computed in different neighbourhoods of Amsterdam based on their similarities with the vision of Sloterdijk One. In the second part of this thesis, the resulting size of the households were used as a design parameter in a custom-made prototype tool to generate semi-automatically several design proposals (called scenarios) for urban developments. Additionally, each scenario can be converted into a Geo format to visualize it in web-based virtual platforms such as Google Earth and Cesium JS. Significant differences among the resulting design proposals based on this new unit of measurement were encountered, meaning that the average size of a household plays indeed a major role.
