House for sale 7+1 • 182 m² without real estateIm Kammerfeld 35, , North Rhine-Westphalia

Individual Architect-Designed House – High Energy Efficiency

– Ideal for the Self-Employed

– From a construction standpoint, it is potentially usable (as before) as a single-family home (approx. 111 m² living space) with a separate practice/office area (approx. 71 m²), but also as a large single-family home or as a “multi-family house” with separated living areas (after a change of use; then approx. 182 m² living space).

Particularly for the self-employed, the division into two legally independent units according to the German Condominium Act (WEG) (residential and partial ownership) is interesting with regard to individualized contractual arrangements. This way, the two units can also be legally acquired separately by the buyer (e.g., spouses)!

The flexible usage options (see floor plan) make the house future-proof for the various family and life constellations that may evolve over time.

Four energy sources based on renewable energies (new heat pump, pellet heating system, solar thermal system, and wood-burning stove) offer high supply security and cost-minimizing flexibility in the use of these energy sources.

Attic (DG)

The focus in the attic is the large, friendly living area with long wooden parquet boards. The spacious open construction with visible roof beam structure and a wood-burning stove creates a particularly cozy atmosphere.

Depending on one’s preference for sun or shade, either the east or south balcony invites you to enjoy a cozy breakfast or a lunch break.

Adjoining the living area are a bedroom (also with warm wooden parquet), a tiled kitchen with a storage room, a shower room, and a small 9 m² room.

Ground Floor (EG)

The ground floor, tiled in a warm beige tone, has two direct access options. On the one hand, there is the main entrance on the west side leading to the practice/office area (approx. 71 m²) with three large, bright rooms, a WC, and a storage room; on the other hand, the entrance on the north side of the house leads to the northeastern part of the ground floor with a shower room and a 15 m² room with a kitchenette and garden access. This area is currently used as a guest apartment (approx. 21 m²).

Both ground floor areas are connected by an inner door.

The ground floor is designed such that it could, if desired (after a change of use), be used entirely as one apartment. For all conceivable cases of room and usage design, kitchen connections have been installed in the practice/office area.

Via the stairwell, the attic and ground floor are connected in such a way that they could together form a 182 m² single-family home (“multi-family house”).

Basement

Dry, highly insulated basement with a ceiling height of 2.40 m, featuring reinforced concrete walls made of C25/30 concrete meeting the watertight quality standard. Two large, heated basement rooms with daylight offer a variety of usage options (e.g., as a hobby, fitness, workshop, or utility room).

One of these rooms (approx. 29 m²) is tiled, has a large window and a wood-burning stove, and is equipped with coaxial/CAT connections for possible use as a workspace.

In addition to the boiler room with pellet silo, pellet boiler, and heat pump, there is a 17 m² room containing the house connections which can be used as a storage room. It is also pre-equipped for use as a laundry room.

Building Structure: Solid construction

• Concrete floor slab calculated on the basis of a soil report, with 20 cm floor insulation (WLG 035)

• Attic insulation with Bauder PIR Plus

• Basement wall with 100 mm perimeter insulation (XPS)

Parking

There is ample parking for several cars on the property (carport plus three additional parking spaces).

For bicycles, there is a lockable bicycle and equipment shed.

Garden

The individually designed garden area offers several cozy spots in both sun and shade (see pictures).

Heimerzheim, with around 6,600 inhabitants, is the largest village in the municipality of Swisttal (Rhein-Sieg-Kreis), located west of Bonn and at the center of the triangle between Bonn, Euskirchen, and Brühl/Cologne.

In addition to everyday shopping opportunities, Heimerzheim features several cafés, restaurants, as well as doctors, pharmacies, therapeutic practices, kindergartens, and schools.

The property is located on the outskirts of Heimerzheim on a low-traffic side street without through traffic. The village center and shopping center (REWE, Aldi, DM, among others) are reachable on foot within a few minutes.

Within a few minutes’ drive, you can access the A61. On the B56, you can reach Bonn-Duisdorf (train station) or Hardtberg in 20 minutes.

There are half-hourly bus connections to Bonn (main station), Rheinbach, or Bornheim, and hourly services to Weilerswist, where there are also DB train stations.

Weilerswist station (on the Euskirchen–Cologne line; Park & Ride) can be reached in 10 minutes by car.

Heating System

High supply security is ensured by two main heat generators (hybrid heating system): on the one hand, a new air/water heat pump installed in 2025, and on the other hand, a pellet heating system.

Currently, the system is configured so that the heat pump, with high energy efficiency, produces the low supply temperature for underfloor heating, while the pellet heating system, in combination with the 15 m² solar collectors, takes care of domestic hot water production. Typically, from April to October, the hot water heating is cost-effectively provided almost solely by the solar collectors in conjunction with a 1000-liter hygienic combination storage tank.

The wood-burning stove for firewood in the attic transfers excess heat via a water-based circuit to the buffer storage, so that in addition to the thermal comfort provided by the stove, heating and domestic hot water for the entire house can be supplied.

Always Fresh Air – Even in Winter! In the ground floor (practice/office area), the integrated ventilation system with heat recovery ensures fresh air at all times, without the need to open the windows.

Internet: Future-proof fiber optic connection by Telekom in the house connection room.

All living areas are individually connected to the house connection point by duo cables (coaxial & CAT), allowing flexible use of cabled satellite and/or internet.

In-House 11 kW E-Wallbox (charging station) for electric vehicles.

Large roller shutters and louvered shutters with electric drive

WERU plastic windows AFINO-one secur II with triple thermal insulation/security glass A1

Soundproof windows WERU Klima Term Phon with sound insulation values of 36/40 dB

Availability: Upon arrangement (even on short notice)

Energy Efficiency: The specified final energy demand (43.6 kWh/(m²·a)) applies to the owner-occupied part. According to the GeG, a differentiation must be made for the practice/office area between the final energy demand for heating (22.8 kWh/(m²·a)) and the (standardized) final energy demand for lighting/electrical energy (37.1 kWh/(m²·a)).

The area calculations were taken from the building permit documents. During the construction phase, there were some deviations in the room layout. No guarantee is given for the exact measurements.

The contractual basis is not the calculated dimensions but the actual room conditions as found during the inspection and review of the property on-site.

In the event that the existing practice/office area is to be used for residential purposes, a change of use must be reported, which is subject to a simplified approval process.
