The physical workplace influences how people work within their environment. Specifically, the design of an environment impacts stimuli that can be encountered in the workplace. With trends continuing towards open floor plan designs, justified by a push towards increased density and reduced real estate expenses per person, it is important to understand how the physical elements of the design impact human capital. This study, looking at varied levels of open plan design, focused on how stimuli is experienced by the knowledge workers in a workspace. Exploring the concepts of prospect and refuge within the workplace environment, the study looks at not only quantifying these metrics, but also how these elements impact the perception of auditory and visual stimuli that is experienced by individuals with varying personality characteristics.
