Company that would have to do with the building of homes in U.S.

Looking for a company to buy stocks in, a company that would build homes or even a company that supplies the wood to build the homes. Which one(s) would these be?

I just want to buy stocks in a company that would have a lot to do with the building of homes nationwide, so if that's the company that supplies to wood to private contractors then that's it. Some company that would be profitable in stocks when homes are actually being built or after they are already built
