An der Schanze is a new-build urban development zone in Vienna’s 21st District. What were formerly argriculture fields in the rich Donaufelder bottom lands between the River and the industrial districts of Floridsdorf are to be developed into a high-density, multifunctional urban quarter. In the Master Plan for the district, developed by Querkraft Architekten, Parcel K is defined as a “New Urban Block”. These blocks are conceived to be very densely built, mixed use parcels which mediate between the high-rise buildings of an der Schanze’s central band and the existing city fabric lying to the south. The site is located on the corner edge of the new district. Conceived in conjunction with feld72 architects (planners for Parcel J) the project forms the south-eastern entrée to the new urban district and frames a green public square, which serves as the focus for the various commercial functions – a city canteen, co-working spaces, small shops, and a dance/movement studio – that fill the ground floor zone.
The countours of our competition-winning proposal grew out of the quite open, yet rather challenging parameters proscribed for the site. With a FAR of 3,2, the zoning for Parcel J is extremely dense, and it is also very complex. While the plot’s maximal building height is generally 16m, in the north-west corner 21m is allowed, and in a 10m stripe along the site’s south edge, the cornice steps down to 7,5m.
Four trapezoidal tracts are arranged around an intimate, semi-private central courtyard. The permissable built volume is strategically apportioned across the site: higher on the perimeter, lower in the center, and stepped down to the south. This distribution of architectural mass produces street fronts well-scaled to the various contexts surrounding the site, and the wall heights of the central court generate a well-proportioned urban space. Four stories above, pleasantly planeted terraces look down on to the courtyard, setting a attractive, multi-level urban room at the heart of the complex.
