House for sale 5+1 • 144 m² without real estate, North Rhine-Westphalia

This single-family house, built in an ecological style, hides a unique feel-good atmosphere behind an unassuming facade: natural materials and light-filled rooms create pure idyll.

Ground Floor – Open, Spacious, Versatile:

A separate entrance leads into a roomy hallway with a direct view into the representative living/dining/fireplace room. Impressive: an airy space with a 9 m high ceiling up to the gable and a gallery that serves ideally as a study. On the ground floor you will find a large bedroom, a daylight bathroom featuring a shower, a bathtub, and a bidet, as well as a guest WC. The large kitchen is separated from the dining area by a stylish wooden and stone pass-through – which can easily be opened to create an open-plan kitchen. The entire ground floor is equipped with underfloor heating and offers potential for additional rooms.

Upper Floor – Flexible for Use as a Self-Contained Apartment:

A solid wooden staircase leads to two charming children’s rooms, an extra room, another daylight bathroom with a shower, and a guest WC. Designed as a self-contained apartment, all kitchen connections are prepared – perfect for multigenerational living, an au pair, or a caregiver. By closing off the air space in the living/dining area, further rooms could be created. The attic, with a wooden window and roof hatch, offers expansion potential and currently serves as storage.

Basement, Garden & Technology – Low Maintenance and Future-Oriented:

The dry and heatable basement with a ceiling height of 2.50 m is versatile and can be developed – ideal for a hobby room, gym, sauna/wellness area, workshop, or home office with high potential for value appreciation. The low-maintenance, level garden with a south orientation impresses with two terraces paved with high-quality natural stone. Here you can enjoy a magnificent distant view and maximum privacy. Energy class A is achieved thanks to a brine-water heat pump with ground collectors – a photovoltaic system would perfect the self-sufficiency. A modern wireless alarm system and wireless smoke detectors ensure safety. The property is completed by a spacious double garage and two car parking spaces.

Located in one of the most sought-after areas on the edge of southern Dortmund, Am Ahlenberg, this property is situated in a small, quiet cul-de-sac. The neighborhood is characterized by high-quality single-family homes, where, among others, doctors, professional footballers, and business personalities reside.

For families, Herdecke is an attractive place to live, as there are several kindergartens, primary schools, and secondary schools. In the immediate vicinity, you will find numerous high-quality restaurants, two riding stables, and two golf courses. Shopping opportunities, as well as doctors and banks, can be found in the nearby center of Herdecke or in downtown Dortmund or Dortmund Kirchhörde, which are just a few minutes away. Medical care is also ensured by the anthroposophic community hospital in Herdecke.

The short distance to the B54 provides access to all the main highway connections in Dortmund. You are also within twenty minutes of Dortmund Airport, making it easy to reach destinations across Europe.

Heating System (Built in 2010):

There are two redundant heating systems that can independently supply 100% of the required heat for both heating and hot water.

1. Heat Pump (HP): This is the standard system.

  The energy for the HP is supplied by a flat collector installed at a depth of 1.5 m in the garden. In addition, there is another redundant collector which serves as extra security should any issues arise with the first collector. It could also be connected to a solar collector that captures heat in summer and stores it in the ground for the winter.

2. Gas Condensing Boiler: Fully redundant to the HP. It is not necessarily needed and would be used, for example, if the HP were to fail (which has not happened for years).

3. A large hot water tank that can be charged by both heating systems.

Radiators:

– Underfloor heating throughout the entire ground floor.

  In the large living area, the underfloor heating pipes are laid somewhat denser to create natural air circulation that supports an even temperature distribution in the large space.

– Radiators on the upper floor.

– Radiators throughout the basement (except in the boiler room).

Thermal Insulation:

– The house was a pioneer in terms of thermal protection and ecological construction. See the attached k-value calculations (thermal transmittance) for the roof, wall, and window areas. These also list the insulation materials and their thickness, with details on the insulation.

– The house walls are constructed as follows: The load-bearing structure is timber framing. On the inside, the timber frame is partly left exposed as a visible structure with brick cladding. The outer walls, which have a cavity, consist of 10 cm of mineral wool insulation, then a 4 cm ventilated air gap, followed by the outer brick cladding.

– The basement walls are insulated with 11.5 cm clay aggregate bricks.
