They have made a statement via the planning officer saying:-
"We can confirm that the adjoining neighbour's private access across the car park area will not be affected by the proposals".
He has owned the property for 12 years, unfortunately his solicitor at the time of purchase did not pick up that the access was not a formalised arrangement, when he then tried to sell the house the new purchasers solicitor picked this up.
Although my son asked the solicitor to chase the brewery to formalise the arrangement, the solicitor never completely solved this, saying that the brewery had not responded
In terms of access he has a side gate that is pedestrian only access, in a public park, which I think closes at night (not sure about that).
His car access is via the ex public house car park, and he has an enclosed parking space on his own land.
This property is on a busy main road with double yellow lines, so no road parking.
Hope that answers your queries
