Oberholz Alpine Hut in Obereggen, Italy
Peter Pichler Architecture
Bauingenieure Hartmann & Gamper
Dr. Ing. Andreas Erlacher
At a height of around 2,100 m you can enjoy a breathtaking view of the dolomites with a delicious meal. Since 2016 these amenities have been available at the top station of the Obereggen skiing area, South Tyrol. The Oberholz alpine hut restaurant, with its exceptional architecture, fits perfectly into the surrounding landscape.
Engineers Daniel Hartmann and Andreas Erlacher performed the structural analysis on a 3D model in RFEM. The company LignoAlp from Brixen was in charge of the design and execution of the whole timber structure.
The structure lies partially below ground level and, protruding from the earth, looks like a tree trunk from above. The ends of the three subtly designed ridge lines are oriented towards individual mountain chains. At these ends, there are large pentagonal panoramic windows that offer a perfect view from the restaurant.
The structure consists of wooden portals, visible from inside and making up the spatial curved structure. The intermediate area which is variable in size and distance has been coated with wooden panels. Each portal consists of three chambers and has a width of 2.50 m in total.
The whole exterior façade including the roof has been coated with larch wood slats, the supporting structure and the interior paneling with spruce wood.
With the Oberholz alpine hut, the planners and executors have succeeded in accomplishing architectural peak performance. Furthermore, the alpine hut has an excellent ecological balance by its use of timber.
