The unique geographical and cultural conditions of Iran bring the diversity in architectural aspects of cities and villages around the country. Following the climatic matters, the contexture of rural settlements are different which leads to create uniqueness in housing styles in these regions.
Also, Since the local architecture of each area affected by its climatic conditions, geographical and cultural matters there; and that the local area housings represent a century of experience in the efficient use of materials, manufacturing methods and climate considerations, etc., thus neglecting this issue (these considerations) could cause the loss of these types of architecture intrinsic values of the local architecture in addition to several years of local engineering experiences.
It seems that the differences in climate around the area of study led to the creation of various kinds of rural housing in the study area. The author of this article examines the different species of rural housing in terms of spatial composition and local structures utilized by indigenous people, with the aim of documentation of species of city's native housing structure and architecture. The methodology of this paper is qualitative and based on theory and case studies arising from data and documents, interviews and observations that had been obtained. Many factors such as climate, materials and construction techniques, etc., which leads to the creation of this type of architecture, are also considered.
Architectural diversity in a limited area is clearly visible. In terms of climate, the contexture of rural settlements are different and this leads to the creation of unique housing species in these areas. And the typology is a way for assortment of rural houses based on forms and spatial correlation plans and the understanding of the forms and plans of the created spaces.
After carrying out investigations on residential houses and drawing out architectural plan of the houses with more than 40 years old, the author concludes that the form of the so called regional houses is following a linear format and were performed in three different plans. The first form rooms are arranged side by side where the Ivan placed in the south side of the building connecting the rooms. The second and third forms were made in "L" shape and "U" shape, respectively. In these two forms, also, an Ivan, which it could been located in west or east direction too, connects the rooms.
Materials used in this region are also native and will be chosen have been chosen considering the climate of the area. Wood is the main material of buildings on slopes and plane areas on mountains and higher altitudes areas the common materials are rocks and soil. The wall's width varies according to the temperature; in which in mild and humid regions it has  less width, and on the other side, mountainous and areas highland, it reaches to more than one meter width.
The building structure type’s fall into four groups: Adobe houses, Larde'ees, Cheane'ees, and combined forms.
At last, the author suggests that by considering the utilization of native local houses even more than before, that consume recyclable native construction materials which do not require any specific foreigner expert to actually construct the house with. By doing so, the harmony of the environment is also being kept sustained. Therefore, it is recommended to regulate policies in order to avoid interruption of the region architectural culture.
