Can you get a feel for how your LA manages planning?
Are they proactive in follow up?
Highways said there's a private road next to the plot so go off that. So new plans have gone in with access off my drive with no consulting with me or checking who owns the land.
I would write directly to Highways pointing out that you dont agree to other households and commercial traffic using your drive.
They wont care about the ROW just that they are signing off on a safe junction.
They have already pointed to how that can be done.
Technical point
You have a drive which is substandard as a road
If the drive cant support HGV etc the builder (&new owners) cant safely access the land.
Most planning has a groundworks clause about building roads up to minimum standard.
I think the Builder should have gotten your written permission if the plan is to upgrade the road junction which is on your land.
Object again if you are in time on whatever section fails the application on missing documents
