The courtyard house is an iconic form of traditional Chinese housing, found predominantly in the central and eastern coastal areas of China. Originally based on the agricultural economy, the courtyard house reflects the close relationship between its inhabitants and nature, with variations responding to prevailing climatic conditions. Built around a central rectangular yard, courtyard houses have relatively generic interior spaces; their actual functions are determined by their position and orientation. In order to take advantage of sun- light and winds, key spaces are usually located along the main axis of the house and face south. Less important and functional rooms are located at lower levels and face north - the cooler and more shaded side of the building.
