The question of how the physical environment of a workspace can impact creativity has been approached from the standpoint of specific, concrete physical variables. To date, no research has categorized different layouts of open-plan offices or examined the different layouts affects on creative cognition and behavior. Consequently, the present study addressed this gap by comparing participants' creative cognition and behavior outcomes in the same room, arranged either homogeneously (low variety, low differentiation, and rectilinear shapes) or heterogeneously (high variety, high differentiation, and organic shapes). Creativity was measured through a similarity finding task and a brainstorming task. Participants' perceptions of the spaces, and what activities should happen in the spaces, were also recorded. A proposed mechanism of the layout influencing exploration and curiosity was explored with surveys. As was expected, participants in the heterogeneous space showed more abstract thinking than participants in the homogeneous space. Creative generation in the brainstorming task was unaffected by the difference in layout. Participants in the heterogeneous condition selected more unusual uses for the space than participants in the homogeneous room. Limitations and a future research direction are discussed.
