User blog:ZooomBlack/Generated Underground House, what should I do with it?

Hey, so, today I found my first Underground house, please do not say I'm stupid towards this kind of stuff, I have just bought the game 4 weeks ago. Anyways I wanted to know, if you have ever found an underground house, what did you do with it? I'm thinking about expanding it, but thats just me. Tell me what you think is better to do.

Please, no harsh comments towards me. Thanks.
