Townhouse with residential and commercial units
The "old bakery" is a beautiful townhouse with over 304m² of living space and 197m2 of commercial space in the middle of the town center of Herzberg.
The house dates back to 1750 and has been lovingly renovated by myself.
I hereby give away my retirement property, because family planning takes me far away and I do not find enough time to continue to take care of the property.
On the first floor of the house there are two commercial units. On the right is a nail studio with 50m² area including kitchen and bathroom. To the left in the courtyard is a rehab and yoga center with 83m² area and in the front left 60m² are currently not rented, however, the yoga center has expressed interest because it wants to expand.
In the front house is a 198m² apartment on two floors with an eat-in kitchen, one full bathroom with shower and tub per floor and a total of 6 rooms. It is currently rented as a WG. Kitchen connections are also available on the top floor, so that a separation into 2 residential units is possible. In the side wing is another apartment with 106m² with full bath, kitchen and 4 living rooms, this could also be divided into 2 residential units, since all necessary connections are already available.
In the courtyard there is access to a ladies and men's rooms visitor toilet, as well as a workshop with car pit and entrance to the boiler room with all-burner and new pellet stove with 3000 liter storage tank and the connection of the vacuum solar panels installed on the roof. The adjacent pellet bunker holds about 25 tons. Consumption has been between 10 and 16 tons for the last 4 years.
Furthermore, there are 2 cellars, in addition to the pellet bunker, which are located under the main house. The one under the nail salon contains a laundry room with about 10m² and a fitness room with about 20m². The second basement is located below the unused commercial unit and consists of a wide hallway and a room with about 24m². The cellars are accessible from the courtyard.
