While owners and municipalities will have to take the initiative to tackle many of their challenges quickly and independently, the full potential to create value through higher-quality, sustainable and resilient buildings and precincts can only be achieved through collaborative engagement between stakeholders and planning that takes into account how multiple forms and levels of obsolescence interact.

Owners will need to assess their portfolios from the perspective of how they fit into their respective built environments and how age, layout and other physical factors affect the ability to better respond to changing locational preferences and exposure to national and local changes to sustainability and development regulations. Public authorities should consider where clusters of similar buildings or uses exist to focus regeneration efforts to catalyze new non-commercial development and inject residential and footfall to boost business activity, while also retrofitting to decarbonize at scale. 

Importantly, this framework for obsolescence emphasizes that strategies do not exist in isolation. Asset repurposing in the form of adaptive reuse, for instance, routinely forms part of post-industrial precinct regeneration, while repositioning product to improve retail provision can be part of incremental improvements to enhance the user experience. In all cases, however, market forces and external considerations will shape time frames, financial viability and quantum of achievable change.
