The research uses a qualitative method. A review of library and also 3d modeling of three types of the Qajar Era houses, led to the selection of 10 houses out of 290 registered houses of this era. The findings suggested an interrelationship among all buildings. The houses are mainly characterized by the symmetry of the windows, doors, and stairways while differing in terms of the decorative work, whether or not the houses belong to the officials, landlords’ livelihood status, and their area. Analyses suggest that most facades have a horizontal skyline and a horizontal rhythm with 1/4 and 1/3 ratios. The main materials used in these facades include woods, stone, simple and colored glass, and glazed tiles and bricks on the bodies. Decorations at the entrances include five-door, three-door, and seven-door designs, mostly made of glass. Thus, it is concluded that the entire facades of this era include visual and mental elements, while other elements are used to strengthen this aspect.

该研究采用定性方法。通过对图书馆的审查以及卡扎尔时代三种类型房屋的 3D 建模，我们从该时代的 290 栋已注册房屋中选出了 10 栋。研究结果表明所有建筑物之间存在相互关系。房屋的主要特点是门窗、楼梯的对称性，而装饰手法、是否属于官员、地主的生计状况、面积等都有所不同。分析表明，大多数立面都具有水平天际线和 1/4 和 1/3 比例的水平节奏。这些立面使用的主要材料包括木材、石材、简易玻璃和彩色玻璃以及主体上的琉璃瓦和砖。入口处的装饰有五门、三门、七门设计，多为玻璃材质。因此，
