The need to limit the consumption of non-renewable resources and energy, combined with the growing attention to climate-related issues, has certainly prompted a greater diffusion of studies and discussion on rammed earth as a building material. An extremely versatile material, easily available and able to meet the needs of different climatic contexts. And it is precisely to rammed earth, often recognised as an ecological material par excellence, that architect Roger Boltshauser has long devoted his research. In particular, the architect's invitation focuses on considering the use of rammed earth in architecture in an innovative way and through new approaches. An invitation answered by the La Galerie d’Architecture in Paris which, from December 9, 2022 to January 14, 2023, presents an exhibition dedicated to a selection of Roger Boltshauser's projects, as well as talks on the theme.
The works on display are narrated through the elegant photographs captured by Luca Ferrario, together with sketches and models made by the architect. The materials selected for the exhibition highlight the close ties and the interconnection between architecture, art and construction, aspects that are deeply rooted in Roger Boltshauser's work. Sustainability, in fact, is the central theme of his works. The unique and diverse portfolio of works created by Roger Boltshauser and his studio ranges from innovative rammed earth buildings, to contributions to urban planning and reflections on historical heritage. In his architectures, form and construction go hand in hand and a holistic, cooperative and interdisciplinary approach emerges, aimed at finding a careful balance of proportions, with a precise structural relief and a unique materiality.
Among the architect's most recent projects, selected for the exhibition, we find the new observation tower of the Ziegelei brick factory museum in Cham, Switzerland, now managed by the Brickworks Museum. A building made of rammed earth, but with some added constructive innovations such as prestressing that strengthens the resistance to seismic loads. The tower, in fact, is the first building in the world made of pre-stressed earth.
