Environmental graphic design (EGD), is also called "Experiential Graphic Design", and uses many design approaches and is mostly dedicated to the creation of 'wayfinding' and brand identity, and designing the look and feel of a physical space.
Environmental graphic design uses and creates the word 'environmental' to describe the place in which you get things done, rather than the natural world. Designers call this a 'sense of place', and achieve it using things like graphic design, architecture, industrial design and landscape architecture.

All sized venues benefit from environmental graphic design, which makes the final result smarter and more impactful, and can help to ensure your organisation ends up with the environment to work, sell and live in that you had dreamt of.
