I'm trying to build a dream HUB, a batcave, a fortress of solitude if you will, but I don't know how. I've been trying for days now but its just not happening. I'd like a place to return to and to add things too, but it's always my house/neighborhood. I want an imaginary place! Something I can build from scratch. Kinda boring having your own house as a dream hub.

Anyone know how to do this?
