Explaining the relationship between spatial organization and orientation of historical houses with emphasis on the role of the entrance(Case study: Vernacular houses of Tabriz in the Qajar period)

This research has been done with the descriptive-analytical method with the aim of explaining the relationship between the orientation of the Qajar houses of Tabriz and their spatial organization from the perspective of the entrance system. During the investigations, the purpose of the entrance design was to target the access path to the yard, and the entrance device plays a significant role in orientation; Thus, despite the multiplicity of entrances, each of them has the possibility of dividing the house into a separate section, and each section can have its own direction and axis. The spatial system of each section is the responsibility of the courtyard (at the entrances of the outer courtyard) and the hall (at the entrances of other fronts), which with the passage of time and approaching the end of the Qajar period and the vertical development of houses, this role has been assigned from the hall to the foyer. Also, organizing with a foyer, unlike organizing with a hall, has reduced the independence and increased the flexibility of spaces.
