Project description
Idyllic and affordable living
in the Mainz countryside
Your new home in Hahnheim!

Project overview
The Weisshorn Group is planning and managing the construction of 42 solidly built, high-quality, energy-efficient semi-detached houses in Hahnheim, of which 34 are being offered for sale. Our offer is especially aimed at young couples and families, and all those seeking generous living space and comfort paired with excellent value for money.
The ground floor welcomes you with an inviting entrance area including cloakroom and guest WC. You’ll also find a spacious kitchen and an open-plan living/dining area of almost 35 m². A large window front creates a bright, welcoming atmosphere and opens up the space toward the terrace and garden.
The upper floor features two spacious rooms of approx. 17 m² each – ideal as bedrooms or children’s rooms. The bathroom includes a walk-in shower, double washbasin and bathtub, and a directly adjoining utility or storage room accessible from the bathroom with connections for washing machine and dryer.
The top floor mirrors this layout with two more large rooms and a central storage space, which can optionally be prepped for a future shower bathroom or finished as a second utility room.
A large attic above the top floor offers generous additional storage space. Each semi-detached house includes a garage and one outdoor parking space.
Our smart heating concept provides infrared heating panels for space heating and heat pumps for hot water, ensuring you benefit from KfW Efficiency House 40 standards and long-term savings. Photovoltaic systems for in-house electricity production complete the energy concept.

The location
Hahnheim is a small yet vibrant community in the Mainz-Bingen district. With around 1,500 residents, the village offers a warm, family-oriented atmosphere. Surrounded by vineyards and meadows, it’s a haven for outdoor enthusiasts. Whether walking, cycling or simply relaxing in nature, this is the perfect place to enjoy your free time.
The area benefits from excellent transport links. The nearby A63 motorway gives quick access to major regional hubs. Mainz, the state capital of Rhineland-Palatinate, is just 15 minutes away by car and offers a wide array of shopping, culture, and educational options.
Nieder-Olm, just a few minutes away by car, also provides great infrastructure with schools, kindergartens, and shops. Hahnheim’s mix of rural lifestyle and proximity to urban centers makes it especially attractive for young families.
The town itself meets all day-to-day needs: a small supermarket, bakeries, and restaurants are close by. Families will find a kindergarten and a primary school locally. Several leisure facilities – including a playground, sports fields, and green spaces – invite active recreation.
Wiesbaden, capital of Hesse, is just 30 minutes away and offers even more cultural and culinary options. The university town of Darmstadt is less than an hour away, and Alzey or Kaiserslautern are similarly easy to reach in the opposite direction.
