The residential project Die Symbiose is being developed in the heart of Hütteldorf, Vienna, combining modern architecture with historic charm. Construction starts in October 2025 and is expected to be completed in the first quarter of 2027. It comprises 21 exclusive owner-occupied apartments with living areas from 30.68 to 151.7 m² and 2 to 4.5 rooms. The development offers high-quality fittings and seamless integration into an urban yet tranquil environment.

The apartments are new builds ready for first occupancy. They feature oak parquet flooring and stylish bathrooms with fine stoneware tiles. Heating and cooling are provided by an air-source heat pump and underfloor systems. Many units include balconies, terraces, or private gardens up to 70.16 m². Orientation ensures optimal lighting, and storage rooms are included in most apartments. Combinations of units are possible to meet individual needs. Energy efficiency is high, with a heating demand of 27 kWh/m²a and primary energy demand of 0.72 kWh/m²a.
