The Circular Built Environment is a field reference for circular-economy practice in architecture, construction, material recovery, and real-estate capital. It names the concepts, patterns, and antipatterns that practitioners currently learn from scattered playbooks, standards, pilot projects, and procurement documents.
The book treats every building as a future material bank. Each entry connects a physical move to its documentation, standards, contract, supply-chain, and finance consequences where those consequences matter.
