"The legislator requires for the EG that the access may have a maximum slope/gradient of 6%. The path will therefore be integrated into the front garden or we will plan a stairlift/lifting platform at the stairs. So there will be no huge ramp there."
I think we will plan a path with a 10-12% slope (max 1x turned) integrated in the front garden with connection to the parking spaces and garden. In addition, a small lift or lifting system at the stairs. But we will only know 100% once we compare costs and possibilities exactly. It has to look right overall and be practical. ;)
It has to be schematically included in the plan anyway, because as already mentioned, the legislator has a say here (from 3 residential units).
