For both myself and residents of number 9, 13, 15 & 17, we park behind my house (number 11) via a tunnel that passes underneath my house. This is a very narrow passage, and requires turning space when exiting/entering the parking yard.
Local residents are aware of this. However, we have ongoing issues with contractors/visitors who do not realise the space needed to access the parking yard.
If it's possible to install a 'no parking' sign or road marking that advises the public, we'd be very grateful.
