Creating a demand for reclaimed or remanufactured components will stimulate the local economy and create new industries, while reducing waste. The built environment demands around 40% of the world's extracted materials and waste from demolition and construction represents the largest single waste stream in many countries. The case studies demonstrate how delightful spaces can be designed from reclaimed products and new materials that are good for the environment and for occupants, as well as saving on construction and materials costs. There are case studies that show how buildings that are designed to be adaptable to different uses can retain value for longer by being more resilient to change in the market. New business models allow short-lived elements of the building to be leased instead of purchased, providing occupants with increased flexibility and the ability to procure a service rather than having the burden of ownership.
