As the built environment sector faces mounting pressure to reduce emissions and construction waste, consultancy firm Arup has released its Reuse Playbook — guidelines for the industry on “a more circular approach” across both new-build and retrofit projects.
This comes as construction consumes around half of all raw materials extracted globally, says Arup in its May 7 press release, with new buildings “equivalent to the size of Paris” erected every week.
Developed in partnership with the Ellen MacArthur Foundation and Circular Leaders Group, the playbook outlines practical steps for developers, designers, contractors and insurers to bring more materials back into circulation and reduce the amount sent to landfill.
Arup says advances in artificial intelligence (AI), digital modelling and structural testing are helping to overcome the cost and technical challenges that have long been barriers to large-scale reuse efforts.
The playbook includes tools such as digital material passports, immersive 3D modelling and advanced testing methods that can help project teams better assess the condition and reuse potential of existing structures and materials.
Anthony Chiu, APAC property, science and industry leader at Arup, says the industry can no longer afford to overlook the commercial benefits of circular design and material reuse, particularly as sustainability regulations and expectations continue to grow. “As an industry, we are glad to see enhanced incentive to move away from demolition being the default position.”
One of the flagship case studies cited is Quay Quarter Tower in Sydney, which claims to be the world’s first “upcycled skyscraper”. The project retained 65% of the original floorplate, preserved 98% of structural walls and core, and saved an estimated 12,000 tonnes of embodied carbon through adaptive reuse.
The 56-page report also points to a growing pipeline of aging buildings globally that could benefit from adaptive reuse. Around 10% of the world’s 40,000 tall buildings are nearing the end of their intended lifespan, though many remain structurally sound and suitable for refurbishment rather than demolition, according to Arup.
Recent technological developments are helping support that shift as well, says Arup. They cite examples including AI-assisted vibration assessments in London, immersive 3D retrofit modelling, and advanced concrete testing methods that allow structural components to be reclaimed and reused in new developments.

Anne-Sophie Duret, green business and circularity lead at AXA, says: “From an insurance perspective, wider adoption of reuse will depend on clear professional recommendations, stronger evidence on performance and more consistent standards across the market.
She adds: “Practical guidance like this from Arup can help developers, designers and insurers make better-informed decisions about the reuse of materials and existing structures, particularly on complex projects where confidence and clarity are essential.”
