House 57 in Barnsbury Gardens keeps blocking the path and road instead of parking in their bay

Owner or Silver car in photo is owned and parked by male at 57 Barnsbury Gardens. The car is constantly parked outside the front of the property, blocking the path and making it extremely difficult for other road users to pass as it leaves very little room again legally parked vehicles opposite. The owner of the vehicle has been asked several times by many residents and neighbours, yet. Still believes there is a right to park there. Can yellow lines be added along the street to highlight to residents where it's appropriate to park?
