Structures which are conceived rationally have an order and logic which do not always fit into real world conditions of the irrational and the unpredictable in architecture. But what if structural ideas were explored as a condition in architecture which challenged the predictable? What if structure were not bound by its rational ethos but instead conceived in alternative approaches relevant to real-world irrationalities? And if the approaches lead to what is possible, then is structural eccentricity a norm or an anomaly in architecture? This book documents a series of design investigations that engage with conditions of shape, change and mutation, giving rise to design propositions dealing with eccentricity in structure. With illustrations and accompanying descriptions of the design process, this book is a useful reference for structural strategies in architecture.
