The architecture of residential spaces in Isfahan has put forward treasured examples to the world of art and architecture through history. House is one of the most important forms of the social organization of space in which numerous factors have been influential in its construction just like many other human-made complexes. Due to the changes in the recent century, historical houses are severely vulnerable to destruction, especially where houses constitute a significant part of the historical fabric of historical cities in Iran, including Isfahan. Modern development is one of the key factors in the destruction of and changes in the physical appearance of historical houses. They functioned as the identity-making element of the historical fabrics. Albeit they enjoyed many values including physical, functional and expressive aspects, they have been forgotten at present and sometimes become a crisis for a neighborhood. The result of disregarding the historical fabrics is to dishonor their historical and cultural identity. One of the worst destructions of the residential heritage of Isfahan is purposeful setting fire to such houses. After the demise of Allāmeh Olfat, his home has witnessed many damages and challenges. This house is one of the types of the Iranian residential architecture that in addition to physical values, enjoy unrivalled expressive and trans-physical indexes. This house was one of the cultural markers of Hassanabad neighborhood in the past, but it has become the least secure spot of the community at the moment. To achieve peace and security, the residents of the area endeavor to destroy this valuable heritage. Its destruction led in the disappearance of the dwelling pattern and its relevant culture. This research tries to explain the physical structure and function of Olfat House for documentation based on oral interviews, private and governmental archives. The main goal for answering the critical question is to provide scientific documentation of the structure by analyzing its physical and functional characteristics to clarify its values as an example of destroyed residential heritage of Isfahan. To carry out the project descriptive-analytical method has been employed aiming at the development and utilizing library sources, photos, maps, field studies, observation and interview. The collected data has been analyzed through a qualitative method by comparison and interpretation. The results reveal the physical and functional values of the house though studying the historical documents and comparing them with several contemporaneous historic houses in the same neighborhood. The Olfat House was of rare houses in the Qajar period which were equipped with a garden and bathroom.
Moreover, there existed a unique system of connections among a number of the relatives’ houses through dead-end alleys and private passages. The life in the said house was in concert with Allāmeh Olfat’s extensive activities. His activities in the field of culture and sometimes production such as rose water production reveal the trans-residential functions in the house.

The Coastal area of Nazhvan is located at the riverside of Zayandehrūd River in the western part of Isfahan. In the gardens of this area which are mostly orchards, woodlands full of fruitless trees, owners have constructed architectural spaces and pavilions. One of the prominent architectural spaces within this territory is a mill known as “Asyāb-e Nazhvān or Hājjī”. There stands a two-floor pavilion on the eastern side of the mill, which is the case study of this paper. This mill is almost the only remaining practical mill in the city of Isfahan. The constructional techniques employed and the addition of the pavilion on the mill are unique. This study tries to scrutinize its structural components. The main spaces, comprising of a five-door chamber in center and two three-door rooms at its sides, stand in the first floor. Besides, some space for facilities such a storage room, kitchen and water closet can be seen on the same storey. There is a three-door room on the second floor which is entirely made of wood, and wooden doors and windows constitute its walls except the chimney and ceiling coating. Now the northern three-door room ceased to exists; therefore, a structural imbalance has emerged on the second floor which ruined the roof of the mill. The field studies reveal that the mill has been built and later this two-floor pavilion was added to it. The constructional timing of the mill and its pavilion needs an extensive discussion which should be done in another investigation. 
After this short introduction, the central question is “how has this two-floor pavilion been added to the mill and what kinds of techniques the mason employed to build the pavilion?” Besides, another noticeable issue is the method used to construct a lightweight pavilion to avoid any excessive load pressure on piers and foundation of the mill. Accordingly, the primary goals of this research are the examination of constructional techniques, (technology of pavilion), how it has been added to the mill, its lightweight construction and deliberate structural documentation of this property. Consequently, execution of this research provides a meticulous study of it which will significantly help to its conservation. Based on the field studies, the descriptive-analytical method was employed for investigation. In the end, the studies show that the piers of the pavilion on the first floor were not consistent with the mill’s piers.
For the same reason, the architect has raised the piers of the mill to build the pavilion. Then, he made a network of poles. The roof of the mill was formed by a traditional method of lightweight construction locally known as “Kenu-bandī” to build an even surface for the first floor. Then after, the piers of the pavilion were installed on the network of poles. The architect tried to create a lightweight pavilion to avoid any extra load on the wooden system. In the same line, he constructed the second floor entirely with wood materials. Through this, the network of poles transferred the pavilion imposing load to the piers and foundation of the mill.
