Lao architecture is mainly a mix of French colonial, Buddhist (in temples), traditional Lao and modern architecture, with some influences from Thailand and other countries. In rural areas most Lao people live in Lao traditional houses, built of wood and raised off the ground on stilts, but in urban areas modern style houses are more common and Lao traditional houses are slowly disappearing. Many ethnic groups have their own house styles, such as the Hmong, Iu Mien, and some other ethnic groups in the northern mountainous areas, where the weather is cold and windy in cold season. These groups build houses on the ground with the end of the roof almost touching the ground.
