aspern Seestadt


Innovative urban development with precast concrete

A perfect example of inspiring urban development is Vienna’s new district of aspern Seestadt. This €5 billion EUR development is one of Europe’s largest development projects and will provide high-quality housing for over 25,000 people as well as 20,000 new workplaces over the next decade. The site area covers 240 hectares – the same size as Vienna’s 1st district. one of the most interesting aspects of the Seestadt is the focus that has been placed on creating a sustainable and eco-friendly development. 

Built for sustainability

The central focus of the city's development is the creation of high-quality housing with the least possible impact on the environment. From the outset, the careful use of resources and building in climate resilience has been a top priority. This has been achieved not only by recycling and reusing existing materials from the site, but also by combining technology and modern methods of construction, like for example off-site construction.

Perfect data with Planbar and Tim

A large number of buildings in aspern die Seestadt Wiens were also built using prefabricated parts built off-site at factories. Offsite-manufacturing offers numerous advantages, especially when it comes to sustainability: industrialized construction accelerates the build process, reduces waste both in the factory and on the construction site, improves quality of the buildings elements, and minimizes disruption to local residents and businesses.

As an example of incorporating prefabrication, a large proportion of the western quarter’s residential blocks were built with precast concrete components which were designed and constructed by Mischek Systembau using ALLPLAN’s specialist precast design software, Planbar. One of Mischek's first precast concrete projects in aspern was the award-winning townhouse “D10”. The townhouse has a low-energy standard and was awarded klimaaktiv silver. Thanks to the efficient design and detailing of precast elements with Planbar, Mischek was able to plan, produce and build the D10 townhouse swiftly and without errors.
