(Yes, it can even be a 2-story house when parked. Horace made the cart and its' enchantments in his spare time.)
"Want me to have Horace open up a spare room? I'm a little nervous about doing this in front of anyone else..." She said as her tail swished from side to side.
Horace shrugged his shoulders. "I have literally no history on this struggle beyond what goes on in old tomes. They never say how it started... or why it was such a great offense that any living Diviner must suffer their wrath." Elistra poked her head through the flaps, and tapped Horace's shoulder.
"Hey, can the rooms be opened yet? I want some alone time with my beloved." Horace did his best to not show interest, though his slight blush would give it away.
"Huh? Oh of course!" He traced his claw on a carved square next to him, and anyone in the cart could see wooden doors appearing on the canvas of the inside. "The kitchen will be ready in an hour or so... dinner an hour after that. Try to not get too far along before dinner is ready, alright?"
"S-Shut it, Dad!" Elistra said as she went back into the carriage.
