"NEW HERITAGE” The studio New Heritage focuses on the existing housing stock within Amsterdam Zuidoost: „Many neighbourhoods face social problems of liveability and demographic changes. Moreover, this housing, like all of our stock, should meet the future standards of energy performance, which leads to an urgent need for energy upgrading. The question arises if keeping this housing is feasible, when taking into account the complexity of technical, social, economic and aesthetic issues.“ (New Heritage, 2020) During this studio the aim has been to develop an answer on the housing stock of H-Buurt, an area within Bijlmermeer, and if it is suitable for further use or not? To make decisions on this, value-based design shall help to extract existing values as well as challenges to get a good understanding of the needs of H-Buurt. THE PROJECT IDencity is located in Hakfort as part of H-Buurt in Amsterdam Zuidoost. The project addresses the non-used car park Hakfort. The car park has been built as part of the expansion plan of Amsterdam in the mid 70’s and was originally connected to the high-rise dwelling Hakfort. The once facilitating function to society is nowadays not given anymore, since the car park finds itself empty and faces demolition in 2022 in order to make space for a new development driven by the municipality of Amsterdam. As original part of Bijlmer’s master plan, the car park incorporates the characteristics of the functional city approach, which puts the car into the centre of the city and gives Bijlmer part of its identity. Therefore, IDencity aims to draw an alternative solution to the demolition by analysing its value from an environmental, social and economic perspective. Programmatically, the project proposes an adaptive, low-carbon transformation of the existing structure into a social hub, while offering an answer to the national housing shortage by adding 120 dwellings. In summary, IDencity aims to push circularity on both a building and a society level by creating places and spaces where the existing is complemented by additions to serve both environment and society. RESEARCH QUESTION How can the adaptive reuse of car park Hakfort offer solutions to current challenges while strengthen the genius loci? Sub question 1: How can the transformation provide an answer to the national goal of carbon neutrality by 2050? Sub question 2: What possibilities of serving the one million homes challenge can be achieved while keeping the existing car park’s structure? Sub question 3: How can the adaptive reuse enhance the buildings’ value to society? CONCLUSION Environmental challenges as well as societal needs have been extracted as key elements of the proposed project. To deal with an existing structure, which is currently not used and to re-dedicate it to society can show value in keeping existing buildings rather than demolishing them. Additionally, environmental goals, like carbon neutrality and circularity can give impulses to confront oneself with the building in depth. In the framework of “New Heritage”, this results in a value based design that extracts values, enhances them and can result in valuable proposals that helps to transition towards a more sustainable built environment. In the case of car park Hakfort, high environmental value of its structure, historical value as part of original Bijlmer, as a functional city, can be used to develop a highly connective building, which interacts with society and surroundings. With its holistic approach, the project tackles relevant themes while offering flexibility to its solution.
