Mackintosh’s avant-garde approach embraced a variety of media as well as fresh stylistic devices. His multi-faceted oeuvre incorporated architecture, furniture, graphic design, landscapes, and flower studies. He embraced strong lines, elegant proportions, and natural motifs, combining an adventurous dose of japonisme with a modernist sensibility for function. He preferred bold black typography, restrained shapes, and tall, generous windows suffusing rooms with light.
