98 new CO2-neutral apartments in Vienna: allocation starts soon!
Viennese living space for everyone! The allocation of 98 new apartments on the Mühlwasserpromenade in the Danube city will begin on November 3, 2025. These apartments are part of the ultra-modern “Municipal Building New” project, which impresses not only with its architecture, but also with its ecological footprint. The building at Brockhausengasse 52-54 will be completed in early summer 2026 and offers both space and a sustainable living concept.
Vice Mayor and Housing Councilor Kathrin Gaal emphasizes that these apartments represent a valuable expansion of the range of social housing in Vienna. With a clear focus on affordable rents, environmental sustainability and a strong neighborhood, this community space will be a new home for over 220 people. What’s special about it? It is Vienna's first CO2-neutral municipal building, which is equipped with, among other things, a low-temperature brine/water heat pump and a photovoltaic system. meinkreis.at reports that the apartments vary in size between 36 and 95 square meters, so there is something to suit every need.
Modern common areas and lots of greenery
Another highlight of the project is the U-shaped courtyard, which is equipped not only with a garden but also with a play area and children's playrooms. The design of the courtyard encourages community activities - open-air cinemas are just one of the ideas intended to bring neighbors together. “We want to create an environment that becomes a living space,” Gaal continued.
If you take a look at the current developments of the “New Community Building” program, the Mühlwasserpromenade is already the third residential building complex in this direction. District head Ernst Nevrivy also announced two new construction projects on Donaustadtstrasse and Weidingergasse, which will provide living space for a total of more than 480 additional residents. To date, over 16 NEW community buildings have been handed over and 9 projects are currently under construction. presse.wien.gv.at shows that so far around 5,700 apartments for around 13,000 residents have been built Vienna were realized.
How do I apply?
For those interested in becoming part of this lively neighborhood, there is a very easy way to register: Anyone who has a Vienna Housing Ticket can register directly on the Vienna Housing Advice website. For many Vienna residents it could soon mean: “Move in and feel good at the Mühlwasser!”
The project shows that Vienna is actively working to improve the rental market while reducing its ecological footprint. The future of living in the Danube city looks promising, and despite the challenges in the housing market, the city government is doing its part to create affordable housing options for everyone.
