A shophouse is a building type serving both as a residence and a commercial business. It is defined in dictionary as a building type found in Southeast Asia that is "a shop opening on to the pavement and also used as the owner's residence", and became a commonly used term since the 1950s. Variations of the shophouse may also be found in other parts of the world; in Southern China, Hong Kong, and Macau, it is found in a building type known as Tong lau, and in towns and cities in Sri Lanka.
