Born as an academic endeavour in Tallinn in 2012, it has grown into a network of researchers and practitioners developing methods, strategies and tools for cities, ministries and international organisations — while staying reserved for the collective projects we truly believe in.
Our approach, metamorphology, reads spatial configuration, human activities and values together: not just how a place is built, but how people actually use it and what they believe it’s worth. The repository on this site is the method’s evidence — every study, with its data sources and its reports, open.
The practice runs from two offices — Helsinki and Tallinn — and develops and runs CoPlanAI, a platform for collaborative urban planning. From 2021 until September 2025, SPIN Unit worked with Toretei on the field application of UrbanistAI, the platform Toretei develops, and some engagements in our record were delivered with it. Ideas and feedback from that fieldwork helped shape the platform’s usability and functionality. The collaboration ended in September 2025.
