The 7xCabin is the result of a workshop focusing on the implementation of a robotic fabrication process on the architectural scale. Instead of inventing a new architectural language based on shifts in technology, this projects searches for an integrative approach towards traditional crafts and archetypal forms.

Using digital design tools, traditional timber joints were adapted to be usable with raw, irregular logs. These joints have subsequently been produced using a chainsaw mounted on an industrial robot. All movements for the robot were planned digitally, with students preparing the exact toolpaths for each log type.

The project was realized by students of ETH Zürich’s MAS CAAD program under the supervision of Tom Pawlofsky. The interplay between traditional timber construction methods and robotic fabrication turned out to be a rich field of learning.
