Adaptive Reuse of Industrial Heritage in Iran: A Sustainable Future for Qazvin’s Flour Factory

This thesis focuses on the adaptive reuse of the historical Flour Factory of Qazvin, an abandoned industrial complex situated in the heart of one of Iran's most historically significant cities. Originally built in the early 20th century by European engineers, the factory reflects a unique blend of local and European construction techniques, with its brick masonry, timber roof structures, and characteristic industrial arches. Over time, due to deindustrialization, socio-economic shifts, and urban neglect, the site fell into disuse, becoming a no-go zone dominated by social vulnerability, informal gatherings, and safety hazards. Our approach aims to transform this neglected industrial relic into a vibrant cultural and educational hub while respecting its architectural integrity, urban memory, and social potential. The proposal integrates functions such as a culinary school focused on Qazvin’s rich gastronomic heritage, exhibition spaces, a food-related museum, local markets, and social spaces to foster interaction, learning, and community cohesion. In line with global sustainability objectives, the project addresses three core United Nations Sustainable Development Goals (SDGs): •??SDG 11: Sustainable Cities and Communities, by revitalizing an abandoned urban site, enhancing cultural heritage preservation, and promoting inclusive public spaces; •??SDG 4: Quality Education, through the establishment of educational facilities, with an emphasis on vocational training in culinary arts and food culture; •??SDG 8: Decent Work and Economic Growth, by creating employment opportunities tied to culture, tourism, and food industries, revitalizing the local economy through adaptive reuse. Our intervention balances architectural preservation with contemporary needs, adopting passive design strategies such as natural ventilation through the original courtyard system, optimizing daylight where appropriate, and ensuring the building’s new layers remain distinguishable yet respectful. Beyond the physical transformation, the project aspires to reconnect the site with the city fabric, encourage social diversity, support economic regeneration, and serve as a model for sustainable heritage reuse in Iranian cities.
