The "Sperlgymnasium", one of the oldest grammar schools in Vienna, was given an extension on the neighbouring property.

Additional classrooms with multi-storey open learning zones correspond to the modern educational concept. A library, the day school centre and the garden are available for afternoon use.

The main entrance and access have been reorganised. A fire protection and escape route concept was drawn up for the entire school.
In addition, the existing building was completely refurbished.
