Austrian architect Wolfgang Tschapeller has won an international competition to overhaul Vienna’s University of Applied Arts.

The proposals include the demolition of an existing link building, making space for the relocation of stairs and lifts to the front of the building.

In a statement the firm said: “The removal of stair and elevator cores displays a pure serial structure. What remains are solely columns and slabs, ready for multiple functional readings. The shelf-like structure will house the studios.”

Two balloons will be anchored to the roof and inflated for special occasions.
