Biotope City Wienerberg is a neighbourhood that has broken new ground in many areas. In this it is part of the great tradition of Viennese housing construction, which for 100 years has repeatedly gone far beyond what was common practice in housing construction at the time with large projects.

Let us recall the Viennese courtyards of the 1920s, in which workers’ housing was self-confidently staged as a major category for the first time. The best-known example of this was the Karl Marx Hof. It, too, was characterised by what has been typical of Viennese housing to date: a focus on social housing, high density, extensive communal spaces and a recreational outdoor area. Another outstanding example is the Alterlaa housing estate (architect Harry Glück), which was built in the 1970s and still enjoys great popularity today with its 4,000 flats in social housing: long waiting lists for vacant flats, swimming pools on the roof and indoor pools inside, numerous common rooms for the residents. Up to the 14th floor, every flat has a large balcony with a 5 m2 plant trough – troughs that are lushly planted throughout and passionately tended by the residents. It is no exaggeration to say that this is probably the only mass housing complex in the world that has no social problems, no vandalism, no crime – on the contrary: more than 30 associations, even its own radio and TV station are run by the residents.

The Biotope City Wienerberg is now part of this context, initiated with élan and vigour by Harry Glück, who has taken up the concept of the Biotope City, the dense city as nature, which is propagated by the Biotope Foundation as an answer to the major global changes in the framework conditions of our urban life.

Some data :

990 flats
2/3 of which are social housing, all with balcony or garden area
2 swimming pools on the roof in the social building
1.720 m² common rooms
1 school, 1 kindergarten
2,000 m² children’s/youth playgrounds
approx. 20,000 m² of commercial space
1 hotel with 152 rooms

990 underground parking spaces under the buildings, leaving deep earth cores between the buildings free for the roots of large trees.

420 bicycle parking spaces

Only 40% of the 5.4 hectare site is sealed and largely car-free.

nevertheless – for the specialist planners:
GFZ ~ 3, i.e. a high inner-city density

The Biotope City concept takes these developments as a basis for planning cities and urban districts of the future. After all, building investments should not only offer a pleasant living environment under conditions at the time of their completion, but also in the decades to come.

Using the regenerative mechanisms of nature – leafs as natural cooling and fresh air machines

Planting of diverse varieties of trees that can grow up to 30 m high – Shade in summer – light and sun in winter after leaf fall

Autumn 2020

Roof gardens and 2 swimming pools on the roof of social housing flats

….green façades – good for cooling, birds and fresh air…

Façade greening also perfect for cooling the surface of the building : 28ºC cooler than without green – important for night cooling !

Many spaces for urban gardening for tenants and owners

Result of all this on hot days:

ø 2,2º C lower air temperature !

ø 23º C lower felt temperature !

The project will get a certification by GREENPASS – the first certification platinum worldwide !
