French Colonial is a style of architecture used by the French during colonization. Many former French colonies, especially those in Southeast Asia, have previously been reluctant to promote their colonial architecture as an asset for tourism; however, in recent times, the new generation of local authorities has somewhat 'embraced' the architecture and advertise it.
There are some colonial buildings as France's legacy in the area, dating back to the 19th and 20th French Indochina colony. Most of them are located in Ho Chi Minh City, Hanoi and Phnom Penh. Saigon - present-day Ho Chi Minh City - and Hanoi as the capitals of Indochina, respectively in 1887-1902 and 1902-1945, present the most exceptional and among the best preserved French colonial buildings in the region including the City Hall, the Saigon Central Post Office or the Municipal Theatre and the Presidential Palace in Hanoi.
French Colonial was one of four domestic architectural styles that developed during the colonial period in what would become the United States. The other styles were Colonial Georgian, Dutch Colonial, and Spanish Colonial. French Colonial developed in the settlements of the Illinois Country and French Louisiana. It is believed to have been primarily influenced by the building styles of French Canada and the Caribbean. It had its beginnings in 1699 with the establishment of French Louisiana but continued to be built after Spain assumed control of the colonial territory in 1763. Styles of building that evolved during the French colonial period include the Creole cottage, Creole townhouse, and French Creole plantation house.
Gabriel Peyroux House in New Orleans, built c. 1780, is an example of briquette-entre-poteaux (brick-between-post) construction.
French settlements in Canada date back to the mid-16th century and until the annexion of Quebec by the British Crown after the Treaty of Paris (1763), French Canada alongside with Louisiana, was immensely prosperous. Hence the abundant architectural legacy from that period particularly in Quebec City but also in Montreal. Most buildings constructed during the French colonial period utilized a heavy timber frame of logs installed vertically on a sill, poteaux-sur-sol, or into the earth, poteaux-en-terre. An infill of lime mortar or clay mixed with small stones (pierrotage) or a mixture of mud, moss, and animal hair (bousillage) was used to pack between the logs. Many times the infill would later be replaced with brick. This method of construction was used in the Illinois Country as well as Louisiana. General characteristics of a French Colonial dwelling included a raised basement which would support the floor of the home's primary living quarters. Exterior stairs were another common element; the stairs would often climb up to a distinctive, full-length veranda or "gallery," on a home's façade. The roof over the veranda was normally part of the overall roof. French Colonial roofs were either a steep hipped roof, with a dormer or dormers, or a side-gabled roof. The veranda or gallery was often accessed via French doors. French Colonial homes in the American South commonly had stuccoed exterior walls.
