Project Heidelgasse

Type of works performed by Alu Alprem:

  • Lift and slide doors
  • Partition walls
  • Roof windows


  • Safety glass
  • Attic conversion
  • Complete renovation of a Viennese bourgeois apartment

The project which we completed at the Heidelgasse Street in Vienna posed a special challenge for installation because of the location of the building. It is located in the centre of Vienna and additionally, elements were built in at the 5th floor. Therefore, a revolving tower crane was needed throughout the entire construction period.

We installed windows in the attic of a Viennese bourgeois apartment. In the bedroom and in the living room, we built lift and slide doors, a strip of top hung windows and a roof window. Elements on the stairs, leading to the rooftop terrace were built from a mullion-transom system.
