A completely new building was inaugurated in 2009, a hi-tech, energy-wise almost self-sufficient, environmentally friendly mountain hut based on wood with an aluminium shell.
The hut can be reached using the Gornergratbahn; from the station Rotenboden a trail leads to the Gorner Glacier (blue and white paint markings).
A new hi-tech environmentally friendly mountain hut was designed by architect Andrea Deplazes of ETH Zurich and inaugurated in September 2009.
The five-story polygonal building was built on stainless steel foundations with a spiral interior made out of wood, the exterior being covered with an aluminum shell.
Bands of windows allow the sun to heat air inside the spiral building with the redistribution of thermal energy produced by visitors.
