This semi-detached house impresses with a well-thought-out room concept, spacious living areas, and a net living area of around 146 m², spread over three floors. The house offers plenty of space for a family and combines practical functionality with a pleasant and versatile living comfort.
In the basement, there is an additional bathroom with shower, sink, and toilet, as well as a washing machine and dryer. A special plus is the cozy living area with direct access to the covered garden seat and into the garden. From here, you can directly access the communal playground - ideal for families with children.
A separate cellar compartment, located in a side room of the parking hall, can be rented from the cooperative for CHF 240 per year.
The ground floor forms the central living area of the house. The spacious, modern kitchen with cooking island opens into the dining and living area, creating a beautiful space for family life. The balcony extends the living area outdoors. The spiral staircase provides direct access to the garden.
On the first upper floor, there is the modern family bathroom with bathtub, shower, double sink, and toilet, as well as the spacious parent's area with office and dressing room. This offers ample space and creates a pleasant private retreat.
The second upper floor offers three flexibly usable rooms, which can be ideally used as children's, work, or bedrooms.
The house has a parking space in the communal parking hall. Additionally, two spacious communal bicycle rooms are available, located directly next to the house.
The house is part of the special residential estate "Am Deich", initiated by the Wohnstadt, Bau- and Verwaltungsgenossenschaft Basel. For the communally used plots and facilities, there is the cooperative "Wohnstadt am Deich". The estate lives from its communal character. Since the Wohnstadt manages itself, with residents voluntarily doing work and participating in the board, the costs for maintenance can be kept extraordinarily low.
