Hmmm. For some reason, Google has discovered that these URLs work (or they would, if I left in the details!):
http://www.streetmap.co.uk/streetmap.dll?postcode2map?code=post+code&title=working+name
http://www.streetmap.co.uk/streetmap.dll?postcode2map?code=firstbitofpostcode&title=working+name
The top one is the one you can now see, nowhere near you. The second is the only other one it knows about, which might be closer but only has the first bit of the postcode. If that actually points to one street away, it's a semi-coincidence (postcode areas are quite large). For me, it doesn't have an arrow at all.
Now, the title can be anything you like. See what happens when you click on this:
http://www.streetmap.co.uk/streetmap.dll?postcode2map?code=SW1A+2AA&title=House+of+EvilNo-one at Google or Streetmap gave that location that title, but it still works as a URL. (It may even appear soon in Google's listings now it's a searchable link!)
So I think that...
I've emailed street map asking for them to remove it so heres hoping it gets sorted out pretty quickly
.. this was a bit of a waste of time.
Somehow Google picked up on the URLs with the postcodes + your working name. How, I have no idea. It's not the whois for your website (which gives the details of the people you got to host it). Using Google's own tools comes up with nothing. It is possible that someone did a query for you with a postcode, just to see if they could find you but this is clutching at straws.
I do sometimes update my adultwork profile and my website from my mobile. I wonder if that has some thing to do with it.
If it does, various people are going to get seriously sued because of the privacy implications!
Who does know your working name and postcode area?
