Bigger listing on google

Can someone tell me how to get the additional pages to show up under the main listing? If you google "Lowes" you can see that "store locator, building supplies, etc...." all show up under the main site. What's that called or how do I accomplish that for my site?

Thanks

These are called site links, you can't make them appear. Its just a sign of a well optimised site, and happens very often when you are searching for brands names, but they can appear for generic terms too. Just conttenstrait on have a well build site with no errors and a nice structure, and maybe do some deep linking.
