Hi what would I have to do to get my website to look like this on a search engine?
Because at the moment my site is just showing the title, url and little excerpt.What area do I have learn to create something like this for my site?
It is called "sitelinks". And yes, you can. If the links are interesting enough, that is.

Of course you need to be the first result on the SERP.
This is incorrect. Although it is rare that more than one returned search result will have sitelinks, I have seen it a few times.
Never saw a website with sitelinks beside the first on the page. and even if you saw a few, it's one in 10,000.
How did you arrive at that statistic given your previous statement:-
Seriously? I just chose a big number, one in a Million, is that ok? a Billion, better?
