This volume explores the concept of "spatial transparency"; a form of spatial continuity that articulates depth through permeable, layered, or porous three-dimensional organizations where interstitial light is present. Although transparency is a concept largely associated with the modern movement, the use of glazed components, and twentieth-century architectural discourse, spatial transparency is a form of depth awareness through intermediate domains, takes place through the interstitial fabric of a structure, and occurs when several consecutive domains are spatially and visually connected. These immersive environments invite active participation, not as one-way communication but as a series of visual and experiential exchanges, interdependencies, and relationships.
