In post-war and post-disaster reconstruction, lifeline systems—water, electricity, transport, housing, medical care, and security—naturally dominate priorities, while cityscape design is often framed as a luxury. This article argues that cityscape is better understood as decision infrastructure: an operable set of spatial rules that reduces uncertainty for returning residents and prospective investors. Drawing on post-war urban reconstruction patterns, the article identifies three strategic models: symbolic-axis reconstruction (e.g., Hiroshima), historic reconstruction (e.g., Warsaw’s Old Town), and modern renewal (e.g., Rotterdam’s pedestrian retail core). Across these models, cityscape affects return decisions by strengthening perceived safety, civic dignity, and a believable outlook for daily life, while it affects investment decisions by making regulatory expectations legible and improving prospects for footfall, dwell time, and revenue. The article then moves from theory to implementation, proposing an operable toolkit across four domains—color ranges, material criteria, outdoor advertising governance, and layered night lighting—organized by reconstruction phases (emergency, transitional, permanent). Rather than treating “beauty” as ornament, the article frames it as urban dignity and predictability: an ethical-operational framework that enables forward movement while carrying loss.
