As Stan says, Guide Post seems the most likely.
In the 1901 census the enumerator's description for 'the whole of Guide Post' specifically mentions Gordon St, amongst others. Unfortunately, though I have paged through all 43 images, he then doesn't mention it or many of the other street names in the description - though there are lots and lots just marked as Private Houses.
Piece 4834, Folio 152 page 1 is the first page in the image set if you want to look through in case I missed it .
