Adaptive Architecture: Shifting Mindsets Towards Cathedral Thinking is a documentary short film project aimed at bringing to the forefront the potential for architects and urbanists to shift their mindset toward cathedral thinking in an age of climate crisis action. At a time when 40% of carbon emissions are related to the construction industry, continuing cycles of demolition and rebuild is not merely unsustainable, but blatantly irresponsible. Through an exploration of global case study architectural projects and interviews with architects and urbanists, the project explores how adaptive reuse, usually an approach associated with heritage architecture, can be brought to the forefront of contemporary practice. Adaptive architecture is presented as an alternative modus operandi for architects to create buildings which are flexible, sustainable, future-proof systems, rather than fixed, immovable objects trapped in a particular context and time.
