Upsides

  • Family-friendly location in Welten with nature, playgrounds, schools, and shopping center all within walking distance.
  • Flexible garden room with a second kitchenette and direct garden access, ideal for entertaining or as additional living space.
  • Recent maintenance including new bitumen roof in 2021 and hardwood frames with HR++ double glazing throughout.
  • Converted garage now serves as a bright workroom with its own entrance, adding versatile space to the ground floor.
  • Energy label B with good insulation features including roof insulation, wall insulation, and draft sealing.

Downsides

  • Electric radiators on the second floor are typically less energy-efficient and more expensive to run than central heating.
  • No garage remains as the original garage was converted to a workroom, meaning no covered parking or storage for vehicles.
  • Flat roof construction, even with recent replacement, may require more frequent maintenance than pitched roofs.
  • Construction year 1975 means the property is approaching 50 years old, which can come with aging infrastructure despite updates.
  • Split heating systems between floors (floor heating on first floor, electric on second) creates an inconsistent heating approach throughout the home.

Description

This semi-detached drive-in home is situated in the child-friendly, nature-rich, and centrally located neighborhood of Welten in Heerlen. The property offers a well-thought-out layout spread over three floors, providing ample living space for families looking for a comfortable and practical home environment.

Upon arrival, the property is accessed via a wide front garden with a driveway that provides parking space. The driveway leads to both the side entrance, the hobby room, and the main front door. The entrance area features a draft portal where the electrical meter cabinet is located. This cabinet contains 5 groups, a 3-phase cooking group, and a smart meter. From this portal, you can reach the hobby or workroom, which was formerly the garage, as well as the hallway leading to other ground floor areas.

The workroom measures 5.30 by 2.87 meters and has its own separate entrance from the front of the property. This space was created in 2020 when the original garage door was replaced with a wide glass sliding door. The conversion has resulted in a pleasant and bright room that can serve multiple purposes, whether as a home office, hobby space, or guest room. The room benefits from natural light entering through the former garage opening, now fitted with quality glazing.

The hallway on the ground floor provides access to several rooms. There is a tiled toilet room with a small sink, a storage room, the garden room, and the staircase to the upper floors. The storage room measures approximately 4 square meters and houses the HR combination central heating boiler. This is a Nefit boiler from 2014 that is included in the purchase. The storage room also offers the convenience of connections for a washing machine and dryer, making it a practical utility area.

The garden room is a notable feature of this property, measuring 4.34 by 3.09 meters. It has a wide glass sliding door that opens directly onto the garden, creating a seamless indoor-outdoor living experience. A second kitchen unit has been installed in this room, complete with a worktop, sink, and under cabinets. This addition makes the garden room suitable for entertaining guests or as an additional living space during warmer months.

The garden itself is well-maintained and designed with various elements to enjoy. It features a terraced area paved with baked bricks, a sunken seating area also paved with bricks, a lawn, and a natural garden section. The garden can be accessed not only from the garden room but also from the side of the property and through a rear entrance, providing flexibility in how the outdoor space is used.

Moving to the first floor, you will find the main living areas of the home. The spacious and bright living room measures 7.60 by 4.34 meters and, like the kitchen, is equipped with floor heating. This provides a comfortable and even temperature distribution throughout the main living spaces. The generous dimensions of the living room allow for various furniture arrangements and create an open feeling.

The kitchen is 4.34 by 3.04 meters and is in a half-open connection with the living room. This arrangement creates a sociable atmosphere where cooking and socializing can happen simultaneously. The kitchen features a line-layout installation with freestanding appliances that are included in the sale. These appliances consist of a gas stove with gas cooktop and electric oven, an extractor hood, a dishwasher, and a refrigerator-freezer combination. There is ample storage space provided by the under cabinets and drawer units.

The second floor houses the sleeping quarters. A wide landing provides access to three bedrooms and the bathroom. Bedroom one measures 4.35 by 3.06 meters, bedroom two is 4.20 by 2.17 meters, and bedroom three spans 5.30 by 2.10 meters. These dimensions offer flexibility in how the rooms are used, whether as bedrooms, a study, or a children's playroom.

The bathroom on this floor measures 2.30 by 2.16 meters and is equipped with a bathtub, a shower cabin, a fixed sink, and a second toilet. This complete bathroom setup means that all daily hygiene needs can be met on the bedroom floor, adding to the practicality of the layout.

The property has several quality features that contribute to its comfort and energy efficiency. All windows are fitted with hardwood frames and HR++ double glazing, which helps with insulation and reduces energy costs. The first floor benefits from floor heating, while the second floor is heated by electric radiators. The roof was renewed in 2021 with new bitumen, providing peace of mind regarding this important structural element.

The location in Welten is described as ideal for families. The neighborhood offers a combination of natural surroundings and urban conveniences. Nature areas, playgrounds, schools ranging from daycare to open university, a shopping center, care facilities, and access roads are all within walking distance. The center of Heerlen is approximately a 10-minute bike ride away, making this a well-connected location.

The property is classified as energy label B, which indicates a reasonable level of energy efficiency. Insulation features include roof insulation, HR glass, draft sealing, and wall insulation. These elements work together to maintain a comfortable indoor climate while keeping energy consumption at a moderate level.

The asking price for this property is 319,000 euros, which translates to approximately 2,398 euros per square meter of living space. The property is available for purchase and the transfer terms are open to negotiation. The property is offered with a full ownership situation for both cadastral parcels that make up the total plot.

This home presents itself as a well-maintained property in a desirable location. The combination of a practical layout, recent improvements such as the roof replacement and garage conversion, and the family-friendly neighborhood make this a property worth considering for those looking to settle in the Heerlen area.
