Published by Taschen, Mackintosh provides a compact insight into the career of the Scottish architect Charles Rennie Mackintosh (1868–1928), who was one of the earliest pioneers of avant-garde and modern architecture, furniture and graphic design. Written by English design historians Charlotte & Peter Fiell, the book is part of Taschen's Basic Architecture series that presents life and work of internationally renowned architects with approximately 120 photographs, sketches and drafts. The series has been edited by German art historian Peter Gössel.

The work of Charles Rennie Mackintosh merged Scottish tradition, modern function, and Japanese elegance into a unique oeuvre across architecture and design. A key proponent of the turn-of-the-century Glasgow Style, Mackintosh also influenced Art Nouveau across Europe with his bold yet lyrical repertoire of vivid lines, elegant proportions, and natural motifs.
