Hermann Muthesius was one of the leading figures in German cultural policy and reform efforts at the beginning of the 20th century. Between 1904 and 1927, he published numerous writings on residential building that were widely received. These include the three-volume work "The English House" (1908) and "How Do I Build My House?" (1917), in which he condensed his design theory into a standard work. The influence and transfer of English teachings on the German development of residential buildings, particularly country houses, are central to the investigation, as are the relationships between modernity and tradition, practice and theory, as well as technology and craftsmanship. For the first time, the book places the architect's design and construction activities, along with selected publications, in a broad cultural-historical context and evaluates them comprehensively against this backdrop.
