Being situated on the edge of deserts and arid regions, Persian (Iranian) cities typically have hot summers, and cold, dry winters. Thus Iran's traditional architecture is designed in proportion to its climatic conditions, and more than often, the unique fabled artistic background of Persia makes up for the seemingly lack of natural resources and beauty.
Iran's old city fabric is composed of narrow winding streets called koocheh with high walls of adobe and brick, often roofed at various intervals. This form of urban design, which used to be commonplace in Iran, is an optimal form of desert architecture that minimizes desert expansion and the effects of dust storms. It also maximizes daytime shades, and insulates the "fabric" from severe winter temperatures.
Islamic beliefs coupled with the necessity to defend cities against frequent foreign invasions encouraged traditional Persian residential architects to create inward seeking designs amidst these narrow complicated koochehs, weaving tightly knit residential neighborhoods. Thus the house becomes the container as opposed to the contained. These houses possess an innate system of protection, they all have enclosed gardens with maximum privacy, preventing any view into the house from the outside world. Hence residential architecture in Persia was designed in a way so as to provide maximum protection to the inhabitants during times of tension and danger, while furnishing a microcosm of tranquility that protected this inner "paradise garden".
Characteristics of traditional Persian residential architecture
Almost all traditional Persian houses were designed in order to satisfy the following essential features:
- Hashti and Dalan-e-vorudi: Entering the doorway one steps into a small enclosed transitional space called Hashti. Here one is forced to redirect one's steps away from the street and into the hallway, called Dalan e Vorudi...
- Convenient access to all parts of the house.
- A central pool with surrounding gardens containing figs and pomegranates tree and grape vines.
- Important partitionings such as the biruni (exterior) and the andaruni (interior).
- Specific orientation facing toward and away from Mecca.
Furthermore,Persian houses in central Iran were designed to make use of an ingenious system of wind catchers that creates unusually cool temperatures in the lower levels of the building. Thick massive walls were designed to keep the sun's heat out in the summertime while retaining the internal heat in the winters.
Persia's distinctive artistic heritage with efficient yet ancient technical know-how thus created houses and spaces whose features were aesthetic talars and roofscapes with intriguing light wells, as well as intricate window and mirror works, paintings and reliefs.
