Form and resistance are the essence of all architectural work. This is especially clear in the interaction between the effect and construction method of façades. They orchestrate the transition between interior and exterior worlds, they manifest the underlying approach and the way buildings behave towards their surroundings. In their articulation of engineering and aesthetics, supporting and loads, proportion and practicality, and rhythm and materiality, they reflect both varying production methods and social value systems. The architect Lando Rossmaier worked with students at the University of Lucerne to study the range of architectural means of construction and expression with respect to Swiss townhouse façades. This anthology presents a selection of around 80 buildings with sensitively developed tectonics, dating from the 20th-century to the present day, all of which have formed a backdrop for an urban way of life for decades. Like a manual, the effect is demonstrated using a photographic portrait and a description of the construction method, using detailed tectonic isometrics. The collection is supplemented by ten projects by contemporary Swiss architects, with essays on their understanding of tectonics. Text in German.
