The main objective of this master's thesis is to revitalize a district in Bandung by means of the adaptive reuse of shared heritage and passive climate systems. Furthermore, the ambition is to empower the local culture of fashion craftsmanship and create a sustainable alternative for shopping in the city centre of Bandung. Designing both a fashion incubator and a public market has facilitated this sustainable alternative. This project focuses on the methodology of the Shared Heritage Lab within the Architectural Engineering graduation studio. First, a thesis was written on low-tech climate strategies in colonial buildings in Bandung. The conducted theory was the leading theme of the design process, in which the existing colonial building of Hotel Swarha is taken as a case study. This resulted in the re-use of the existing concrete building, a new wooden structure, a bridge, an enclosed courtyard garden and a new roof that extends both constructions. By using existing resources and a low-tech building approach, newly built buildings can be more sustainable, reducing building waste and energy consumption. By hosting craftsmen and entrepreneurs from the local fashion industry, the local community is encouraged to develop a more sustainable style with a regional character. The heart of the existing building serves as a learning platform for designers. The ground floor, the new building and the roof act as a public and independent market that is semi-outdoors, which extend the urban footprint of the city centre of Bandung. This design project and case study of Hotel Swarha is a successful example of the reuse of shared heritage and passive climate technologies, focusing on context, climate and community. The results of the design project show that this low-tech design requires minimal energy consumption while aiming at a high level of comfort, ultimately benefiting the urban microclimate. In addition, creating an open market is a reinvention of the shopping experience in Indonesia, with a focus on the growth of local entrepreneurs and sustainable production.
