The publication of the twentieth volume of the annual yearbook from the Faculty of Architecture and Landscape Sciences at the Leibniz University Hannover is cause for a small celebration. The HOCHWEIT yearbook provides an insight into teaching and research in this top-ranked faculty and into the creativity, analysis, and research involved in work being done at the university. A large number of design and teaching events, research activities, lectures, excursions, workshops, exhibitions, and expert subject discussions are presented in order to illustrate the faculty’s activities. HOCHWEIT introduces the varied, multi-faceted faculty and its nine institutes in the research and teaching areas of architecture and landscape architecture, the building and construction sciences, and environmental planning.
