Rethinking Kållered; from big box to a reuse hub; a transformation journey toward sustainability

Abstract

In the current efforts to meet growing demands, routine practice is turning to the demolition of structurally sound buildings for the construction of new ones, despite conflicting with the United Nations’ Sustainable Development Goals. In an ecosystem focused on economic and time efficiency pressures, the reuse of existing infrastructures and materials is often overlooked. This thesis explores the potential to transform the recently vacated IKEA store in Kållered, Sweden, into a community-focused “Reuse Hub” instead of demolishing it. Built in 1972 and after serving for fifty years, the building was slated for demolition to make room for a new shopping center. Challenging this, the study aims to create a model for circular and sustainable economic practices that meet the needs of users at all levels, promoting resource efficiency, waste reduction, and a shift in societal consumption patterns. As a result of a comprehensive methodology including literature and case study reviews, visits, and discussions with reuse-specialized companies, the project conceptualizes a multifunctional space. It encompasses a largescale store for reclaimed construction materials, areas for construction businesses with sustainable practices, public workshops, and educational facilities. Various reuse-focused stores for reclaimed items are supported by communal areas such as food services, and seating areas to facilitate social interaction among diverse user groups and transition between spaces. The key findings demonstrate that the project offers a feasible solution to the issue of reusing large vacant commercial properties. It makes reclaimed materials and items more accessible, proving that reuse practices can become the norm for both individuals and institutions, significantly contributing to a circular economy. The multifunctional approach does not only reuse an existing building but transforms it into a platform for learning and innovation, and a space for societal change. These findings contribute to the discourse on sustainable development and circular economy practices, providing insights to replicate similar initiatives in other contexts. It highlights an alternative that could significantly reduce the construction sector’s environmental impact. Beyond environmental benefits, it also illustrates how sustainable practices in the construction sector can catalyze a wider shift towards sustainability across society.
