Herbert Ypma, the world-renowned author of style and travel books, created an entirely fresh and innovative approach to interior design in ''World Design'', his series of visual sourcebooks for designers, architects, artists, students and everyone in any way interested in home decoration. Morocco is at once ultra-modern, yet still deeply traditional, and this is what defines Moroccos decorative arts. Featured here, for example, are a villa in Essaouira, traditional and contemporary homes in Marrakech, an Islamic pleasure pavilion, a contemporary mud home in the Palmerai, a Berber mud village, and Majorelles garden in Marrakech.
