A practice of the virtual offers to interior design a dynamic conception of interiority that transcends simplistic representative notions of space, recognising the inseparable relationship of space and time, as well as an understanding of interiority as lived experience and its attendant amenability to active interpretation and therefore design. Ultimately, a practice of the virtual facilitates an understanding of interior as a dynamic and ongoing network of relations, and interior design as individuating participation in this network. In this article, we describe in detail an expanded notion of the virtual, and extrapolate how an understanding of this notion might help shape future interior design practice. We then offer some examples that might help translate these ideas into practice.
