Maybe spongebob squidward or the chum bucket. Think about it, the chum bucket is a home and a restaurant at the same time and there's actually comfy rooms amd you can eat the food that no one else wants.

Yeah, but Sandy's tree dome has all that futuristic science stuff.

Of these, SpongeBob's pineapple, though I personally think I'd live in this here banana (from Unreal Estate):

SpongeBob's house.

Squidward's house has the nicest interior out of all these houses.
