In a quiet, well-established residential area of Ober-Mörlen, a modern apartment building with a total of 24 high-quality residential units is being developed, ideally combining contemporary living, sustainability, and a high level of comfort. The architecturally clean-lined building blends harmoniously into the predominantly residential surroundings and impresses with its well-considered orientation, generous spacing, and attractive open-space design. The building will be constructed as a climate-friendly Efficiency House 40 and meets the requirements of the Quality Seal for Sustainable Buildings (QNG). As a result, residents benefit not only from consistently low energy costs but also from a healthy indoor climate, high construction quality, and long-term value retention. Heating is provided by modern air-to-water heat pumps in combination with comfortable underfloor heating in all apartments. All units are barrier-free and easily accessible via an elevator. Generous ceiling heights of approximately 2.60 m (around 2.70 m on the ground floor), floor-to-ceiling triple-glazed windows, and electric shutters ensure bright, welcoming living spaces with a high quality of stay. Terraces, loggias, or rooftop terraces extend the living area outdoors, offering private retreats with an appealing residential atmosphere. The apartments’ fittings meet high standards of design and functionality: elegant multi-layer parquet flooring, modern tiles, stylish sanitary fittings from renowned manufacturers, and a timeless interior design create an atmosphere that is both refined and comfortable. The thoughtfully designed outdoor areas, featuring a shared garden, play areas, and landscaped green spaces, invite residents to linger and encourage a sense of neighborhood community.
