The digital has expanded the medium of architecture, bringing with it a focus on architectural surfaces. This paper presents a theoretical discussion centered on spatial æffect or how architecture operates as an atmospheric machine. The argument is that architecture’s double, atmospheric and meaningful architecture, architecture that affords mental transport across time and space, emerges when instead of focusing on the backdrop to the action or on surfaces, architects consider dimensionality and play with the experiential assemblage of the many material and immaterial elements that constitute space. Engaging in the production of architecture’s double is not only necessary for creativity and spatial diversity, but also for enchantment, which can drive attachment to places and help create and sustain a sense of belonging.
