The historic houses of the Qajar era are among the remarkable works of this period, which, due to their close connection with the everyday life of the people, are indicative of the special characteristics of their time. These houses are not only important in terms of plans and architectural spaces, but also unique in terms of decorations and arrays and cultural values. Thus, this paper is aimed at understanding the residential architecture and its design patterns in Qajar houses in Isfahan. The research methodology is analytical and descriptive and has been done with library and field method. Special attention has been paid to the design and spatial designing patterns and by analyzing, analyzing and comparing them, the further categorization of cultural factors and design patterns in Vasigh's home has been provided. Actually, As  space organization is considered an integral part of traditional Iranian architecture, In a way, it shows the application of spaces, Also, they represent the dominant thinking of their age. Due to the necessity of his time, the Qajar art faced Western elements and reacted itself selfishly. The result of this response to the design of the architecture is that in many cases the imported elements have been able to combine with the traditional elements. At home, we also encountered spatial patterns that clearly illustrate this issue. At home, we also encountered spatial patterns that clearly illustrate this issue. But in general, artists of this era have been able to achieve unity in the design of the architectural design of this house, despite the combination of elements of different cultures.

Nowadays, urban planners are encountered with Urban sprawl in the large cities, especially in the developing countries. In order to control this condition they have taken different policies, one of these policies are increase density. The aim of this research is to determine the optimal building density in Isfahan's fifth district. To analyze this subject, firstly the selected district was divided into several quarters (neighborhoods), the indicators in each quarter were studied and weighted according to their suitability for the proposed density, then the weight of each index was established by the use of comparison matrix and eventually the suitability of each quarter was determined to propose the increase of density. The findings of the presented research indicate that because of the specific qualifications of the district, such as the existence of the valuable historic fabric of Jolfa and its neighborhood with Zayande-Rood, the historical center of the ChaharBagh-e-Bala and width of the passages and …, it`s better to avoid the increase of density in this district; and finally some suggestions is presented in order to determine an optimal density for this region.
