The Impact of Exterior Additions on Cohesive Design Relationships: Heritage Buildings of Sulaimani City as a Case Study

The addition is one of the important concepts that accompanied the history of human civilizations since ancient times. It represents a civilized product that embodies human cognition as well as social and utilitarian demands throughout history. Designing for the historic context inherently brings challenges and necessitates a comprehensive understanding and sympathetic analysis of all aspects of the existing structure or buildings. A comprehensive understanding of the nature of heritage structures, as well as conservation philosophy, may help guide interventions or new additions. Will result in the most efficient adaptation process, preserving the original characteristics while developing the new structure. The aim of this study is to determine the compatibility of the new addition's architectural expression in relation to the characteristics of a heritage building. This technique is based on architectural and statistical analysis, which considers the heritage character of a historical structure in relation to its values. According to the results, the nature of additions should first be clearly characterized, and each new addition should reflect the identification of its own time. Rather of changing the scale or shape of the old structure, a new addition should complement and contribute to the feeling of proportion, emotion, and historical formation.
