Spatial Design is the design of human environments. It incorporates aspects of interior design, architecture, urban design, performance, art, and visual technologies. It involves studying the relationships between people and their environments, and designing ways to improve those environments.

People are enclosed or enveloped in environments of many kinds. Such spaces can be defined by four walls, but equally they might radiate outwards with few physical boundaries and change with time. They might be defined by proximity: how far you can reach or travel; intimacy and the desire for closeness; immersion and the sense of being fully engaged or even out of your depth; drama and suspense; touch, warmth, pressure, the feel of the breeze or the shock of pain; or connection, whether through genealogies, social networks, or remote technologies. Spatial designers recognise that we experience our world from within.
