Brand new hospitals, known as ‘Super Hospitals’ are being built in various Danish cities at the moment. This entails that the many former hospital buildings are being abandoned and this is the exact situation that will be happening in Aalborg within the near future. In this regard, this thesis will address how to transform some of the old building masses into innovative architecture housing new functions that are needed in the particular part of Aalborg having the history, identity, and architecture of the place in mind. In continuation hereof, a main focus of this transformation thesis will be sustainability and re-/upcycling of materials. This topic on transforming architecture is highly relevant to the present, due to the fact that the building industry is a highly polluting industry and in order to reach the national climate objectives of 2030* and 2050** radical changes must be implemented in order to obtain a greener industry. Transformation- and renovation projects of abandoned buildings are likely to be one of the new solutions; in 2020 Rambøll published a report on this specific topic, concluding that renovation projects can reduce the emission of greenhouse gases of up to 56 % when compared to demolishing- and rebuilding projects. This thesis will investigate and study the many - often neglected - possibilities within the architectural field of renovation and transformation, with a vision of repurposing the existing building mass. Concluding, the concept True North proposes a vibrant and livable area of co-existing functionalities designed for the multiplicity of users and local community. True North showcase the example of how various initiatives of modern sustainable architectural design can be integrated when transforming the existing building mass, strategically working with the upcycling of materials and the repurposing of those. * 70 % reduction of national greenhouse gas emissions compared to levels of 1990 (Sørensen & Mattson, 2020). ** Complete national climate neutrality (Retsinformation.dk, 2020).
