Over the course of his career, Herman Hertzberger has made a great many theatre designs for sites both in the Netherlands and abroad. They are presented here together for the first time in book form. In a long interview with Arthur Wortmann, the architect explains what designing theatres means to him. Armed with many examples from his own work and the work of others, he describes how a theatre ought to slip into its urban surroundings, the considerations that obtain when designing the auditoria and the secret of a good foyer.
