Abstract
This article introduces the topic of revitalising outdoor common spaces in existing housing developments. The aim of the research is to present universal design models by analysing nature and heritage as dominant values, complementing perceived natural and cultural deficiencies. For this purpose, the Sustainable Development Goals (SDG), UNESCO (UNESCO, 2015) and the Research Through Design (RTD) method were used. The Zaspa housing estate was chosen as the research area because of its characteristic urban layout and its high cultural and social recognition. As a result of this research, elements of the Sustainable Development Goals (SDG) were identified and analysed. Graphic spatial models from the projects, were divided into groups for which the intensity of the contribution of nature or heritage to social inclusion was determined. The next important step was the international validation and participation in the European Heritage Days exhibition and the verification of the results of the citizens’ survey opening the second phase of the research. This article summarises the first phase of the multi-year research project.
