Airstream on a cliff

Refuge Gervasutti by LEAPfactory

This is a great idea: a prefab climber/hiker refuge that’s airlifted into place and assembled in a few hours. The Airstream trailer of refuges. I wonder how this idea might translate into low cost housing on level ground?

My only concern is that in the example refuge the front door is a bit too close to the drop off and in icy or snowy conditions one might, uh, have a bad day.
