Description
4.5 rooms on the top floor with gallery and south terrace in a new building
This 4.5-room owner-occupied apartment on the top floor south combines spacious living areas with the special character of a high-quality attic space. The consistent wooden construction, visible wooden elements, and the use of loam in the interior design create a warm, natural living atmosphere and a pleasant room climate.
Particularly noteworthy is the open gallery with around 24 m², which expands the living area by an additional, versatile level. Together with the main usable area of around 111.8 m², a living area of around 135.8 m², including the heated gallery, is available. The gallery is ideal as a workspace, library, retreat, or additional living space.
The open living, dining, and kitchen area, with the visible roof construction, forms a bright and characteristic center. From here, you can directly access the approximately 11.5 m² large, south-facing terrace.
The three rooms, with around 13.1 m² to 17.7 m², can be flexibly furnished as bedrooms, children's rooms, guest rooms, or home offices. Two separate wet cells provide additional comfort; in one of the wet cells, a bathtub is possible as an alternative. A practical reduction with its own washing machine and tumble dryer is directly provided in the apartment.
Oak parquet, wooden windows with triple glazing, visible wooden ceilings, and roof surfaces, as well as surfaces with lime-loam plaster, give the apartment a high-quality and natural appearance. The kitchen, sanitary appliances, and floor coverings can be co-determined within the planned budgets.
In addition to the basement compartment of around 10.1 m², an attic area of around 35 m² on the gallery level offers additional storage space. The apartment also includes parking space No. 6 in the entrance hall. The wheelchair-accessible lift comfortably connects the entrance hall and the underground floor with the top floor.
This attic apartment is aimed at buyers who are looking for spacious living space with its own character, natural materials, and modern building technology.
