What does residual plots mean? The information may be outdated.
Neighbor's house is located to the west, landscaping has not yet begun. The neighbor has built a natural stone wall to the south, nothing has been done at the boundary yet, it is currently partly cut away and somewhat gravelled for the driveway, I do not know the exact plan, I have to inquire.
What do you mean by shaft? A channel? One is in the curve, it is visible on the site plan, another one further down the street, so at the end of the southern adjacent property.
Variant 2 revised attached..
Picture 1 is a view from the south onto the neighboring plot, mine is basically to the right of the wall, Picture 2 is on the southern boundary towards the west..
