During the French colonial period in Lao PDR (from 1893-1953), France integrated its architectural elements into traditional Lao architecture and modified them to suit the climate. The French colonial style continues to make a modest impact in most major towns and cities. The harmonious combination of traditional Lao architecture and French colonial influences shows the true values and wealth of a city's characteristics. These unique architectural styles and motifs are valuable to the area's heritage; many of these styles are still conserved today, especially in Luang Prabang, which was designated as a World Heritage city in 1995. Some historical buildings have been adapted according to social and economic factors.However, as elsewhere in Indochinese countries, the provincial French design was modified to suit the hot and humid tropical climate. The design of colonial villas, in turn, began to influence subtle changes in the design of Lao urban dwellings. This paper discusses the development of traditional Lao architectural styles and the effect of Nano technology in this style, that have been experienced in Lao PDR, analyzes the process of change, emphasizes the importance of compatibility between traditional house form and the French colonial house, and studies of the factors like Nano materials influencing the transformations of traditional housing.
