If me and my cousin did go to a library what would we look for to find out more about my aunt's house?

You need to give way more info if you are looking for help.

If you are looking for records of previous owners or a history of the house then a city hall or other place would have that kind of information. If you are just looking for information about the design of the house and what not you would like to search in the non-fiction section under architecture. However, like ja77 said, I can not offer much help without further information.

Hi, supernx5!

What are you looking for concerning your aunt's house, please?

Thanks!
