Hanno Burtscher (supervisor rammed earth)

Born 1977 in Fontanella Hanno Burtscher grew up in a small village in midst the Austrian Alps. Nature was always present and served as the stage for the main activities throughout his childhood and adolescence.

Subsequently, when he began to study architecture in Vienna, he had to balance the non-materialistic part of design-and concept study throughout the year at university, with something tangible, (a project he could get his hands dirty with), during his summer holidays. Working onsite on building developments seemed like the best fit.

He met Martin Rauch, and the rammed earth construction technique, in 1998 for the first time. He’s been actively engaged in an art, discipline, and profession of rammed earth ever since. Under the careful mentorship and guidance of Martin Rauch, he gained his knowledge, years of hands-on field-experience, and mastery in rammed earth construction.

Hanno has also been working as an entrepreneur, working independently on his own projects, spread around the world.

Building with earth, and ultimately sharing with the future occupants of earth structures, the experiences and innate benefits which earth brings, drives all of Hanno’s work.
