By the end of 2023, a modern residential building with 49 units was completed at Rudolf-Simon-Gasse 5, setting new standards for sustainable and future-oriented living. Designed by Riepl Kaufmann Bammer Architects, the building is heated by an eco-friendly heat pump with geothermal probes, ensuring a pleasant indoor climate even in summer – entirely CO₂-free. Each unit features a private outdoor space, whether a balcony, terrace, or private garden. Additionally, residents can enjoy a communal garden and a spacious rooftop terrace for relaxation. Sustainable mobility is supported with charging stations for electric cars and e-bikes, along with approximately 100 bicycle parking spaces. This tranquil residential location offers local amenities and outstanding public transport connections. The rapid transit railway (S-Bahn) provides access to the central transport hub Wien-Mitte in less than 15 minutes.
