Extremely spacious family home, usable in two separate parts

This extremely spacious family home (370m²) is very quiet and surrounded by greenery. It is atypical in that it has no fewer than four floors, with currently two living areas, four bedrooms (potentially six), and four bathrooms. It also has two separate entrances, which means that part of the house could be used entirely separately as a practice space (liberal profession), student rooms for rent, Airbnb, or a kangaroo home for parents and/or children. Because there are currently two living areas, this house has the potential for 6 bedrooms (after installing a few partition walls). There are currently 4 bathrooms, but there is enough space to give each bedroom its own bathroom. The house has either a terrace, balcony, or garden on each floor. Another unusual feature is that the garden is located on the second floor at the rear. This is because the house is built on a steep slope. Another possibility would be to rent out the second floor (which has completely separate access) after refurbishment/renovation as 2 student rooms (600 euros/month/room) or 2 AirBnb rooms (400 euros/week/room) and live in the rest of the house (still approx. 300m2 and 4 bedrooms) yourself. 

On the ground floor, the house has a spacious garage for one car (a second car can also be parked on the street in front of the garage), basement rooms, and a laundry room. In short, an atypical family home that is one of a kind. But maybe just what you are looking for?
