Inspired by an idea submitted under the "Grätzlmarie" scheme, Wiener Wohnen was able to upgrade the design and ecological value of the forecourt of the municipal housing complex at Klosterneuburger Straße 99-105 in the 20th district. An asphalt surface with an area of approx. 170 m² was unsealed, and new greened areas were installed to improve the microclimate, reduce the urban heat island effect and promote biodiversity. The project involved the planting of around 500 shrubs, including the heat-resistant "Seven-son flower" — a first for Wiener Wohnen. The measures were implemented in close consultation with Municipal Departments MA 28 – Road Management and Construction and MA 42 – Parks and Gardens. Launched in March 2025, the project was already completed in May 2025. The creation of this green oasis has significantly enhanced the design of the public space and helped to adapt it to climate change while simultaneously enhancing the amenity value of the neighbourhood for local residents and passers-by.


Takeaways & challenges

  • The project was initiated via the WieNeu+ "Grätzlmarie" scheme and was able to be rolled out thanks to the dedicated work of the WieNeu+ Coordination Point team at Wiener Wohnen.
  • The extensive redevelopment of the forecourt would not have been possible without the financial support from WieNeu+.
