The style of architecture and type of settlement vary according to the region in which Greeks live. Greeks who lived in Georgia and other mountainous Caucasian areas traditionally built houses similar to those of Georgians and were known for preferring large buildings. A wooden upper floor with a balcony is supported by a stone lower floor, which houses the kitchen and storerooms. In poorer, rural areas of the Caucasus and Georgia, such as Tsalka, dwellings were often built into the hillside, sometimes using mud bricks in addition to stone and wood. In recent years, the style of buildings has been changing; larger houses are more prevalent and the use of traditional materials has decreased. Certain neoclassical details such as columns and pediments are frequently found in the architecture of Greek communities.
