Throughout this Dissertation one of my prime objectives is to reveal that Art Nouveau Architecture and design achieved far more than merely a new form of decoration. I aim to achieve this by providing a detailed appraisal of the aesthetic and practical qualities of many buildings. While aesthetics often provide the clearest under¬ standing of the style, issues such as planning, services, structure, and materials are of equal importance. These more practical aspects of building can often affect a design more than anything else, and while my research has revealed little information on these issues, what has been found will be included and extended upon wherever possible. Most of this will be based on personal architectural experience, and the belief that architects and designers of the Art Nouveau Movement were faced with similar problems as we are today.
