Ok we got you with the title, but you are not expecting country house splendour here are you? You are right.
But with a bit of shovel work (about 4 tonne) a home was excavated and the kettle put to good use.
For those with a head for the figures the snowhole had two entrances, three rooms, two wardrobes. was 7m from front to back and had a maximum span of 2.5m. The snow was over a metre thick over the highest part of the cave. The temperature inside was a consistent zero degrees whilst outside it was horrible!
