>> Several aspects were combined in one project: modern production methods, sustainable energy management, rapid provision of high-quality housing, multiple temporary use - all within the scope of affordability. <<

A new era in housing.
The housing estate in Podhagskygasse is one of the pioneering projects of the instant housing construction program launched by the City of Vienna in 2016. A new funding scheme has been set up for this program. The basic idea is to promote low-cost housing on currently unzoned or barred plots of land. What is special about this is that the buildings are "only" temporarily erected and have to be dismantled after a specified period of time (in Podhagskygasse after 10 years), but can be re-erected at another location. The property in Podhagskygasse is suitable for such a housing development due to the current zoning conditions, so the pilot project could be realized between 2017 and 2018. The period between the start of construction and the first occupancy was only 9 months, in compliance with current quality standards. Through subsidies, affordable housing can thus be made available in the shortest possible time. The project thus heralds a new era in housing construction when it comes to affordable, quickly and temporarily available housing.
The concept of temporary housing-on land not currently designated for this purpose but basically usable-makes an important contribution to the provision of housing in a growing city. Alternative concepts are of great relevance, especially in view of the dwindling availability of land and rising land prices. New social qualities can arise in such laboratory situations. As a platform for innovative solutions in social housing, the IBA_Vienna is accompanying the project in Podhagskygasse and will make the findings visible to a broad public
Housing in a modular system.
The project in Podhagskygasse impresses with its extremely short construction time and a high degree of flexibility. These qualities are achieved by the easily adaptable timber lightweight modular system. Prefabricated room cells can be stacked as required. Two different module types form the basis for five different apartment types between 30 and 100m². The room cells are industrially prefabricated and only need to be stacked and joined together on site. With a view to efficient (dis)assembly, an infrared heating system has been installed. Due to the free arrangement, the entire complex is crossed by green space, the ground floor zone is fully accessible for people with disabilities.
Temporary housing: sustainable and cost-effective
The modular system in Podhagskygasse is designed to be dismantled after 10 years and rebuilt at least two more times at other locations. With regard to the construction method, it is a climate- and resource-saving housing solution. The conscious and reasonable use of resources in the course of industrial prefabrication also makes an important contribution to future "urban mining". Due to subsidized housing construction, the housing space can also be kept affordable for the residents.
