This rapport shows two different vernacular buildings in Nepal, one in a warm temperate climate, Kathmandu, and one in an alpine climate, Upper Mustang. Kathmandu is located in a hill and has a warm climate during summer and in winter the temperature can drop down to around 0 degree Celsius. In Kathmandu there is monsoons every year which effects the architecture of the house as well as the temperature drop in the winter. Thakmarpha is in the mountains and has a characteristic of cold and dry climate as you can see in the diagram below. It is expected that the architecture of this region is adapted to the cold winters and not so much for the rain. Therefore, the buildings in the alpine regions should prevent the conduction of the heat to the outside and also exploit the sun to store heat as much as possible.
