An Algorithmic Approach for Spatial Design of Post-Disaster Settlements Considering Prolonged Stays

Abstract

Post-disaster settlement designs often prioritize urgent needs while overlooking the frequently
observed reality of prolonged occupancy. The neglect of diverse long-term needs and
expectations commonly leads residents to undertake costly and uncoordinated modifications.
This study proposes the creation of spatial variety within the parcels of individual dwelling
units in order to enrich and support future modification possibilities. Spatial variety is achieved
through the combination of two spatial properties—open/semi-open space and hard/soft
ground conditions—resulting in four spatial configurations within each parcel. This approach
is developed in relation to the principles of incremental design and long-term experiential
quality that is livability. Employing a research-by-design methodology, the study develops a
generative algorithm capable of generating spatial configurations of post-disaster settlements
while respecting the widely-accepted dimensional standards. The model is tested through a
pilot settlement scenario. The findings demonstrate that generative algorithmic approach can
support diverse user expectations in post-disaster settlements.
