The experience garden “Arabellas Garten”, designed by a landscape architect and featuring a pergola and quiet oases, gives the project a special atmosphere and creates a place for encounters and communal living.

The energy concept sets new standards: air-source heat pump, photovoltaic system and green flat roofs ensure permanently low operating costs. In addition, the project has been assessed as capable of achieving ÖGNI Pre-Check Gold Standard.
