“If you could eat it, you’d call it superfood.” This is how the organizers whet the appetite for the exhibition on Roger Boltshauser and his clay architecture. It should be sufficiently well known by now that clay is a moisture buffer and fire protection, has a balancing effect on the indoor climate, keeps wooden structures dry, can be found almost everywhere in the world and is easy to work with. And yet we cannot talk enough about this building material and promote it.
An exhibition in Stuttgart does the same and shows the work of Swiss architect Roger Boltshauser, who works a lot with clay construction. For him, it is “a kind of fundamental experience” that still spurs him on today, makes him courageous, but also critical of all conventions and constantly drives him to find new solutions. Boltshauser then became known to a wider circle in 2008 when he and Martin Rauch built the latter’s single-family house from rammed earth in Vorarlberg (Baumeister 7/2009). At the time, it was still said that they were building “at their own risk”, a test building. The realization required ten to twenty times less energy than a conventional concrete or brick building. However, the amount of work involved was very high.
Some clients are now also enthusiastic about earth building, and a few larger earth buildings have already been built – such as the Ricola Herbal Center by Herzog & de Meuron or the Alnatura office building by Haas Cook Zemmrich. Boltshauser is working on a number of promising research projects and is also planning large buildings made of rammed earth. In his opinion, the future belongs to intelligent hybrid constructions. His colleague Martin Rauch is convinced that the next decade will be an era of earth building. It brings a new aspect of responsibility to planning and building – “simply building, putting perfectionism into perspective”, as he puts it(Baumeister 6/2021).
In this respect, one can never make enough pleas for earth building – as the architect will certainly do in his opening speech at the Weißenhofsiedlung in Stuttgart next Wednesday. The exhibition on Boltshauser aims to show that in his work, art, design and construction combine in “constant parallel processes”. Some of his collage sketches will therefore also be on display. Ultimately, it is clear that Roger Boltshauser is concerned at all levels with the search for an authentic answer.
