In the house there is a book called A Dance in Fire, Book III on a bookshelf on the top floor which raises one's Athletics skill. Since Uuras is an Athletics trainer, then it's likely he reads that to hone his skills.
In his house there are many balls of yarn, and also some cheese, probably which he produces with his sheep. On top of his house there are three chests which may contain some iron of steel equipment. The Hero can use his bed without trespassing or other illegal things.
Most of the time it is locked and there is no one inside of it.
