yes, the road forms a loop around the building above the pinned location but doesn't end on the north of the building, it continues then to the east and joins back the D10. Which means it is possible to enter the property at the Y fork south, and exit again on the D10 further north without tracking back on that private road.

That road is visible on google maps and correctly traced in their data.
