This diploma thesis deals with approaches, strategies and perspectives from various disciplines and fields which can contribute to sustainable urban development and open space design. On the basis of literature analytic methods aspects of town and transport planning, urban design, architecture, ecology, socio-economics, politics, philosophy and permaculture from the perspective of open space design and landscape architecture are presented and analyzed, with a direct, specific reference to the urban region of Vienna is produced. Further urban utopias, theoretical methods and selected recent examples are provided. Therefore, by the discourse of literature the results are summarized, compared and analyzed and a general, extensive and broadly diversified picture of a possible “green city of the future” is integrated, outlined and discussed. The developed general application strategies for sustainable urban development and design of open space include, among other things, the use of synergistic effects between the city and surrounding areas for example by means of post-industrial re-use of regional parks, the promotion of a polycentric, compact urban structure and small-scale, functionally mixed neighbourhoods in terms of a "city of short ways" with low mobility and high permeability of open space, the use of ecological, economic and social potential of public and private urban green and open spaces through "Urban Gardening" and urban permaculture and the promotion of ecological construction through the greening of roofs, facades and courtyards. Consequently, the developed application strategies should also contribute to the general discourse of sustainable urban development and open space design as well as to a specific discussion and application in the context of the urban region of Vienna.
