Charles Rennie Mackintosh's finest work dates from about a dozen intensely creative years around 1900. His buildings in Glasgow, and especially his craggy masterpiece the Glasgow School of Art, are more complex and playful than any other work in Britain at that time. His interiors, many of them designed in collaboration with his wife, Margaret Macdonald, are both spare and sensuous; creating a world of heightened aesthetic sensibility, especially inside the Willow Tea Rooms or The Hill House. And his inventive imagination, which played constantly with the shape of curves and squares, produced designs for furniture which transformed ordinary chairs into pieces of abstract sculpture. Finally, in the 1920s he painted a series of watercolours which are as original as anything he had done before. Since his death, Mackintosh has been lauded as a pioneer of the Modern Movement and as a master of Art Nouveau. This book, with illustrations that include specially prepared plans and sections, takes a clear-eyed view of Mackintosh and his achievements, revealing a designer of extraordinary sophistication and inventiveness.
