In a quick glance at the houses in Yazd, not much is seen more than cob and mud, but while passing through these houses and valuable buildings, one is amazed by its diversity, facade, detail, form, volume, and space as well as functionality. We, as passengers and observers, are surprised by the environment and climatic factors such as wind, sun, and plants. The need to design a Home arises this very moment but can only be properly resolved to by recognizing the vernacular architecture and adapting it to the needs of the time.
The premier concept for this house is based on a brief study of various types of traditional houses in Yazd and the city’s climate. The process of concept formation is described below:
The general form of the designed house is a combination of three common types of traditional houses in Yazd:
The trihedral of single yard pattern (Kolahdouz-ha House), external and internal courtyards of the two-yard patterns (Lari-ha House), houses with
Godal-Baghche (Taraghi House). The result of these three patterns is modernized in the design of the home and the trihedral house with the pattern of external and internal courtyards, which includes Godal-Baghche.
Climate studies indicate that annual thermal fluctuations in Yazd is 41 degrees Celsius and the daily thermal fluctuations are around 20 Degrees Celsius. This difference in temperature is due to the lack of adequate humidity in the air. The aforesaid issue was resolved By placing the pond and green space in the innermost "Darooni" courtyard because the water of the pond creates evaporative cooling while leafy trees’ shading In the summer in innermost courtyard and wall of the building creates a cool atmosphere with optimum moisture for comfort in warm and dry seasons. The trees allow light to enter the building in cold seasons by losing their leaves.
Same as the walls of the city that provide security against human invasions and wildlife, the walls of the house are in charge of shielding its interior from the outer world. In the design of the house, we tried to preserve the privacy of the traditional household and its spirituality. For this purpose, the hierarchy of the inner and outer boundaries of the yard separate the guests from the permanent residents of the building. The people on business enter the house directly from the courtyard to the workroom. Members of the family and close relatives are allowed to enter the private space and the inner courtyard. We find that the inner courtyard is used as the second living room in the summer season. For this purpose, Space is placed on the second floor.
In the zonings devised according to the employer’s daily activities who spent most of her time in the kitchen, it is placed near the inner courtyard in order to use natural lighting during the day. An unbroken line of sight from the kitchen to all public spaces of the house is provided on the first floor and maintained through other levels. There exist a hierarchy in the privacy of the spaces from the first to the last level where the utmost isolation is provided.
Regarding the selection of materials, brick was chosen as a vernacular option that has a high thermal capacity and low heat transfer capability. In addition to the climatically suitable features of brick, this element has always been of great importance to Iranian architecture, especially in the southern regions and its application in the building can affect certain qualities, such as permeability, belonging, sense of richness, and the form quality. On the facades, the shadows are created by pushing parts of the wall back and forth which will have a significant role in reducing the temperature inside the house.
