4 -  Afterwards, Inuit people started to build the so called turf hut, the tiny houses made of earth and timber, in order to provide even more insulation opportunity than snow igloos. The common turf house has large foundations made of flat stones and upon this was built a wooden frame which would hold the load of the turf; the turf would then be fitted around the frame in blocks often with a second layer, or in the more fashionable herringbone style. The only external wood would be the doorway, which would often be decorative, and it would lead into the hall with commonly a great fire. The floor of a turf house could be covered with wood, stone or earth depending on the purpose of the building; they also had grass on the roof.
