The real question is, you say "it can be any kind of house..." Does it have to be a house in a traditional "walls and roof and foundation on the ground" kind of house, or can I, say, live in a massive airship? Or a giant, 300 foot tall, 1000-foot wide, armored all-crushing megacomplex on indestructable treads and bristling howitzers? Can I hollow out the moon and call that my house?
