Window web weaver .......

I am absolutely clueless when it comes to spider identification, all I can tell you is that this guy is literally hanging about outside my dining room window.

Siting his / her web here is strategically a questionable decision as every time there is a strong wind or heavy rain the web gets damaged and it seems to spend a considerable amount of time effecting repairs.

Please, if you know what species of spider this is leave a comment, it would be much appreciated.
