Large amounts of material waste resulting from the renovation of post-war housings pose a great challenge for managing waste through destruction. Applying the concept of the circular economy may allow the opportunity to reuse these materials that would otherwise be thrown away due to renovation. The article explores the possibility of embedding Buildings as Material Banks (BAMB), a circular economy concept, at the neighborhood scale. Through holistic macro planning, BAMB will be embedded in the renovation process of the post-war neighborhood in a step-by-step manner to realize the reuse of materials. Although the article investigates some cases of reuse of old materials, due to the limitation of length, the study did not make detailed adjustments and adaptations to the site, Western Garden Cities. Specific materials from the Western Garden Cities will be studied in future studies.
