We discuss increasingly behaviour-responsive Adaptive Architecture from an em- bodied point of view. Especially useful in this context is an understanding of em- bodied cognition called ‘the 4E approach,’ which includes embodied, extended, embedded, and enacted perspectives on embodiment. We argue that these four characteristics of cognition both apply to and explain the bodily interactions be- tween inhabitants and their adaptive environments. However, a new class of adap- tive environments now expands this notion of embodied interactions by introduc- ing environment-initiated behaviours, in addition to purely responsive behaviours. Thus, we discuss how these new environments add the dimension of bodily reci- procity to Adaptive Architecture.
