In Metzerlen-Mariastein, you can expect an exceptionally versatile property: a detached single-family house with plenty of space, a spacious garden, and interesting long-term development potential.
The residential building from 1948 extends over the basement, ground floor, and upper floor and currently offers around 111 m² of living space, including the heated winter garden with a Swedish stove. This glazed living area is one of the special features of the house. With around 19.8 m², it expands the classic living space and creates a bright, protected living area with direct access to the terrace, garden, and landscape.
On the ground floor, there is the living/dining area, the kitchen, a bedroom, a bathroom, and the central corridor. The heated winter garden complements this level with an attractive additional living area.
The upper floor has two more bedrooms, a bathroom, a corridor, and two separate storage rooms. This makes this floor ideal as a private sleeping, children's, guest, or work floor.
The basement also offers a remarkably large room layout. Here you will find a spacious technical room, a separate laundry room, another bathroom, the oil tank room, and a spacious storage room/natural cellar.
Together with the additional storage spaces and the spacious garage, around 115 m² of usable and secondary space, including the garage, are available.
The house corresponds to an older construction standard in various areas. This is precisely what gives new owners a lot of leeway for individual modernization and further development.
However, the combination of the existing residential building and the approximately 980 m² large plot of land is particularly interesting. This makes the property suitable not only for families and owner-occupiers but also for investors, project developers, and builders who want to exploit the long-term potential of the parcel.

Location
Metzerlen-Mariastein stands for natural living, a lot of greenery, and a pleasant, rural atmosphere. The property at Challstrasse 26 benefits particularly from its direct connection to the surrounding landscape. The rear area of the property opens up to the green space and conveys a pronounced feeling of width and privacy. The winter garden, terrace, and garden are oriented towards this open outdoor area and create an attractive connection between living and nature. The spacious property is accessible via Challstrasse and also has an existing lateral access. The combination of a quiet, rural environment, a large property, and long-term development prospects makes this property particularly interesting for both private buyers and professional real estate actors.

Others
Of the total approximately 980 m² of land, around 967 m² or 98.7% are in the two-story residential zone W2. Within this zone, single-family homes, semi-detached houses, row houses, and multi-family homes with up to five residential units are generally permitted. A concept and feasibility study for a possible development with four row houses has already been created for the property. The current working assumption provides for two full floors and a fully developed attic floor and assumes around 140 to 150 m² of usable living space per unit, or a total of around 560 to 600 m². This opens up interesting perspectives for investors, project developers, or builders, in addition to the use and modernization of the existing single-family home.
The available project and feasibility documents can be made available to qualified interested parties upon request.

Important note:
The presented development opportunities do not constitute a building permit or a binding building law assurance. The definitive utilization, number of residential units, building arrangement, parking, and usable areas are to be examined within the framework of a specific preliminary project by the buyer or their architects and the responsible authorities. Furthermore, there are street construction lines and registered building rights on the parcel, which must be taken into account during planning.
