In reply to girlymonkey:
That little house is where it is for a reason.
It's marked as "Plan God Nair" on the map:

Note that it's to the west of the obvious avalanche zones - two of which are even called "Laviner da l'aua" and "Laviner Lad". Laviner = avalanche.
No doubt one day it will be wiped out but the historical record suggests that it's in a relatively safe place.
For a good example of a 500 year avalanche event check out the February 1999 events in the Val d'Herens which wiped out several buildings that were supposed to be completely safe.
