Dropped kerbs and planning permission - Public forum - Planning Advisory Service (PAS)

I would be most grateful for clarification on whether householder or full planning permission is needed for the creation of a vehicular access / dropped kerb onto a classified road from a dwelling.  My understanding is that full pp is needed because the red line must extend to and include the kerb, hence it would be outside of the residential curtilage and could not be a householder.  I wondered if officers could let me know their thoughts and how they typically approach this?

Many thanks
