That's right. Warm. So how could the inside of a "snow house" be so roasty toasty?
Air pockets in the snow make it a surprisingly effective insulator. With outside temperatures as low as -50, inside temperatures range from 20-60 degrees Fahrenheit just using body heat.
Igloos have been used for many years as temporary and permanent housing in Alaska, the Canadian Arctic, and Greenland. Complexity of construction varied depending on how long the igloo would be used. Some igloos incorporated skins/hides on the interior to help retain heat. Typically, a raised sleeping platform was fashioned, elevating the person into the warmer air higher in the structure.
