I see, I need to explain the property more precisely: The house is located in the second row with access (right of way) over another parcel. The access ends in front of the house, but the garages are on the other side of the property. The square 480m² plot is not large. The house is built on the boundary with a 5m distance from the garages, which are also built on the opposite boundary. There is one single and one double garage. In front of the garages and the house, which is also the driveway to the property, everything is paved; behind that is a tiny garden. To reach 60% sealed surface, I would either have to tear down the garages, which I do not want to do because they are built better than the house; one garage is needed anyway since there are no parking spaces in the street and the other is used as a cellar substitute. Tearing up the paving stones and driving over mud to the garage is also not reasonable.
