Façade design recommendations towards visual compatibility of infill buildings with the Qajar architecture of the cities of Mazandaran province

In the current study, an endeavor is undertaken to formulate specific recommendations for the design of facades pertaining to infill buildings situated in the proximity of valuable urban Qajar residences within the Mazandaran province. The conspicuous lack of such directives within the regulatory framework of this region is noteworthy. The imposition of guidelines pertaining to façade design is imperative to establish visual congruence between contemporary structures and historical Qajar edifices in the urban landscapes of Mazandaran province. The present investigation employs a comprehensive approach, integrating both the interpretive-historical strategy and the logical argumentation strategy. A scrutiny of 30 valuable urban Qajar residences in Mazandaran province is conducted, wherein their distinctive features are systematically classified under eight discernible categories. Subsequently, a conceptual framework is developed by leveraging Semes’ design strategies model and drawing inspiration from Groat’s theoretical framework. Concurrently, the practicalities inherent in Mazandaran’s urban conservation system are taken into consideration. This conceptual framework serves as the foundation for the articulation of facade design recommendations, delineating acceptable design methodologies for its constituent elements. Within this framework, a concerted effort is exerted to advocate conservative strategies for the macro elements of facade design, juxtaposed with latitude for more abstract approaches when addressing the micro elements. It is noteworthy that the intentional opposition approach is deemed unsuitable. Ultimately, drawing upon typological analyses of the compiled samples and adhering to the established framework, a series of recommendations for facade design is proffered. This study serves as a foundational step toward the formulation of design guidelines tailored to the historic districts of Mazandaran.
