Urban development VIERTEL ZWEI Plus, Vienna

Green islands


VIERTEL ZWEI has been one of the most successful residential projects in Vienna since its completion in 2009/2010 and an exemplary European showcase project for sustainable urban development. Today more than 4,500 people live and work here and enjoy the 5,000 m² lake and over 13,500 m² of green and open spaces. Two further planning areas, the VIERTEL ZWEI Plus, around the Wiener Trabrennbahn, expand the quarter by 80,000 m² with new office space and innovative residential projects.

Everyday supply facilities and the connection between living and working create short distances and enable a low-traffic infrastructure with e.g. e-car sharing offers. Great importance was attached to a cooperative planning process in the development of the district in order to involve all stakeholders.

The open space design is characterized by a central square that emphasizes the center of the quarter and a modeled landscape of “Green Islands”. With playful ease, various green and open spaces for encounters, play, relaxation and infrastructure are condensed in a flowing up and down of gentle hills and valleys to form a strong atmospheric image of a contemporary concept of architecture and landscape. In the central square, this picture finds its special expression in the coming and going of the water in a fountain game - if the water goes, a freely usable center of the square is created at intervals.
