Thanks Hugo ... for bending the rules a little!
I worked out where it was, got the Lodge name by zooming in on the Google Maps pic, got the road name because that was on the map, and the post code I got by using Gridref finder, and that gave me the LL18 code.
Yet Google Maps goes to the same location when you key in the LL22 code that you quoted!
Must have been a lodge for Kinmel Hall originally.
