A study of the continuity of architectural identity through visibility analysis Houses in Erbil city as a case (1900-2020)

This study aims to study the continuity of architectural identity in the houses in Erbil city for the period (1900-2020) through the analysis of visibility, using (space syntax-depth map X 0.8) to conduct visibility analysis and identifying the 2D isovist polygon from the first point of the urban threshold between the street as a public domain space and the private spaces of the house which is referred to as a point (A). The research concludes that the change in architectural identity due to the change in private-public threshold in the houses of Erbil city has effect on the 2D isovist area, and the ratio of visibility of private spaces in the house from the observation point (A). The research contributes to studying the continuity of the tangible identity of architecture via the analysis of visibility of the interior spaces of the building from the first point of the public-private threshold.
