Heffinger Interiors is a multidisciplinary design studio creating residential, commercial and experiential environments. Every project starts with a big idea, the thing that makes a space unmistakably yours. We refine it, then carry it through every detail to installation, so it looks beautiful and works for real life. We’re an interior designer in Glen Ellyn, Illinois, working with clients nationwide.
