Mariusz G. Polski MSc. Arch. of Delft University of Technology defines metastability as a term which describes the extended duration of certain equilibria acquired by a complex system when leaving its most stable state aIer an external action.
Considering the contemporary technological levels and multiple scientific insights into natural systems that reflect metastable tendencies, it is not hard to imagine an open ended architectural design that across its life span reveals metastable qualities. It is a design that incorporates contemporary tools as a communication medium with the cultural environment and assumes uncertainty to be a planed and valuable part of the process, producing architecture that facilitates environmental feedback and drive its evolution towards internal and external homeostasis.
