The entrance is via a separate external staircase on the right side of the house. The balcony, with an area of 6 square meters, serves as a small terrace. The living/dining area features a fireplace.
The spacious bathroom was renovated in 2015 and has a very large window front.

The living/dining area and bedroom have laminate flooring. The hallway, kitchen area, and bathroom have tiled floors. Some of the windows have roller blinds and blinds. The entire living unit has underfloor heating. A storage room in the basement is also included with this unit.

Apartment on the ground floor:
The living unit was last renovated in 2022. It features a sunroom with direct access to a private garden and a spacious terrace of approximately 21 square meters. A fireplace can be installed in the sunroom/living room; there are two chimney ducts available. It has its own entrance on the front of the house. The entrance area is bright and inviting. The living/dining area and kitchen are modern and open-plan. Bathroom with a window and a ground-level shower. All windows in the rooms, except for the entrance hallway, are equipped with shutters. The entrance area, living/dining area, kitchen, and bedroom have laminate flooring. The bathroom has tiled flooring. This unit also features underfloor heating (not in the sunroom).

A basement room is also included with this unit. Ground floor apartment:
Separate entrance on the side of the house. The kitchen, living, and dining areas are also open-plan. A fireplace can be installed in the living area. A spacious terrace area of approximately 20 m² extends from the living/dining area. The bathroom and second bedroom were newly renovated in 2025. The living and bedroom are equipped with shutters. In addition to the kitchen, there is a small storage room.
The bedroom has laminate flooring, while all other rooms have tiled flooring. This apartment also features underfloor heating. The sewage pump will be replaced in 2026. The house has a new, modern condensing oil heating system (2024) with a central hot water tank (2025). It is expected that the energy consumption will be significantly lower than before, as indicated in the current energy performance certificate. The data used comes from the heating periods prior to 2015 to 2024, using the old oil-fired boiler that had been in service since 1989. The initial forecast from 2024 shows a significant decrease in consumption. However, the new high-efficiency boiler was only installed in April 2024, meaning that the full impact will not be reflected until the end of the heating period. Therefore, instead of the current energy demand level F, which is 162 kWh/m² per year, we can expect an energy demand level of approximately D, which is 125 kWh/m² per year.
