Mainz-Kostheim, Kostheimer Landstraße 25

The Project

The Architecture

The building has been carefully integrated into its surroundings. The modern apartments impress with their successful combination of light, exclusivity and optimal functionality. The effect of the floor-to-ceiling windows with delicate divisions is emphasized by the transparent balcony balustrades. Colors, shapes and materials are harmoniously coordinated.

The Construction

The building is constructed in solid masonry and meets all requirements in accordance with the German Building Energy Act (GEG) 2024. Foundations and base slab are made of concrete. The exterior walls and load-bearing interior walls are built of sand-lime brick or reinforced concrete. The floor slabs are made of reinforced concrete. The staircases are also constructed in reinforced concrete and finished with polished granite steps. A thermal insulation composite system (ETICS) is applied to the exterior masonry.

The entrance system, made of lightweight metal profiles with insulated safety-glass door, is equipped with an electric door opener, door closer and door holder.

The Outdoor Areas

Driveways and walkways are paved. The remaining site areas are laid with turf. Specimen trees, shrubs and ground cover plants are added to complete the landscaping.

Wiesbaden

Mainz-Kostheim

Mainz-Kostheim is a district of the Hessian state capital Wiesbaden and is located directly at the confluence of the Main and Rhine rivers. Although its name refers to Mainz, Kostheim has administratively belonged to Wiesbaden since 1945. Its unique location between two major rivers continues to shape the area to this day. The protected landscape area “Maaraue” makes Mainz-Kostheim a highly sought-after residential location for those who wish to live close to the city yet connected to nature.

The district retains a well-established, partly village-like character. In the historic center, narrow streets, half-timbered houses and the Catholic church of St. Kilian – considered a local landmark – create a charming atmosphere. Schools, daycare centers, medical facilities and shopping opportunities provide excellent infrastructure. Along the Rhine riverbank, green spaces, walking paths and allotment gardens make Kostheim a popular recreational area.

Bridges provide quick access to Mainz, while convenient connections to Wiesbaden and the entire Rhine-Main region are also available. The Mainz-Kastel/Kostheim railway station and several bus lines ensure excellent public transport links.

Overall, Mainz-Kostheim combines urban proximity with a waterside setting close to nature and maintains a unique identity shaped by its history between Mainz and Wiesbaden.
