German architect, he was primarily a designer of domestic architecture, much of it with medieval vernacular motifs, steep roofs, and turrets. His Motive der mittelalterlichen Baukunst in Deutschland (Themes in Medieval Architecture in Germany—1896–1902) and Ziele und Ergebnisse der italienischen Gotik (Italian Gothic Objectives and Influences—1912) prompted some early C20 architects into exploring how medieval architecture might be a starting-point for contemporary design. His drawings of buildings in Egypt and the Middle East (published 1907) had an impact on Behrens and others who sought to simplify design into blocky cubic forms. Among his buildings his own house and others at the Villencolonie, Grünewald, Berlin, of the early 1900s, deserve mention.
