Ajarían homes and agricultural buildings are notable for their original design. The oldest types of dwellings are the patskha (a type of wicker hut) and the jargvali (a wooden structure). The most developed and widespread forms of traditional homes in use today consist of two or three stories. This building style is dictated by the needs of animal husbandry and agriculture. The first floor is generally utilized as a manger, the second story contains the kitchen and the common room where the family gathers, and the third floor is used for sleeping and receiving guests. Ajaria has two basic types of settlement, not counting intermediate and mixed forms: in one type, the houses are arranged in a row; in the other type, the houses run along the crest of a ridge. Agricultural, geographic, and social factors have contributed to the development of these types of settlements.
