There is a missing road here acknowledged by Ireland's Government known as "Orchard Lane".

Orchard lane is technically a public road leading to a single house, 1 Orchard Lane, Herbert Park

If you look up the Eir Code (the official irish postal code) D04 P5Y3, you will see this road acknowledged.

You can also see this road clearly marked on Google Maps, Bing Maps, Tom Tom Maps and any sort of Aeriel views as well.

Note: you are also missing the square for the house.
