Two parts of the BG/BRG Gänserndorf were extensively thermally renovated and extended by a three-storey extension. This connects the two existing buildings with each other. The centrepiece of the new building is the "New Centre", a central auditorium that spans all floors and is a place of exchange for the students. A large number of decentralised break areas invite students to linger between lessons. The annex provides access to the existing sports hall wing, where the music classrooms are also located. Thus, a school from the 1970s has been transformed into a modern and open place of education. In the entrance area, a forecourt with seating elements and a pergola connects the grammar school with the adjacent regional swimming pool. Both schoolyards provide access to the generously multifaceted school garden.

About 60 per cent of the building is heated by a geothermal heat pump, which required 34 boreholes, each 150 metres deep. This also allows the school to be cooled in the hot summer months. The two existing buildings were brought into the future thermally, both the façade and the roofs were insulated and extensively greened. The ventilation of the classrooms is CO2-controlled. The 150 kWp photovoltaic system on the roof provides electricity.
