Shah Alam has exhibited flourishing cul-de-sac courtyard neighbourhoods, which has stirred debatable interests. The objective of this paper is to continue the discourse in measurable analysis of sub-classifications. The paper assembles physical data with key characteristics that make-up the physical construct of a cul-de-sac courtyard by administering measurements, observations and checklists. The sub-classification processes led to preliminary key factors such as density, size, design forms and user implications. 18 cul-de-sac courtyards in Shah were catalogued and inventoried, elucidating its syntax. The database introduced potential in longitudinal research of the socio-spatial micro-neighbourhood unit, towards pragmatic applications in emergent design practices.
