Larger Moghouse

I wanted to know if it was possible to have a larger moghouse not the storage part of it but a bigger floor or even a stair case that goes up behind the fireplace/waterfall/stove to a second floor?

I'm on of the people who has 80/80 safe for furnishing alone as much as i would love to see furnishing get their own storage (via special furnishing storage) i would love to have a second room to decorate or even a quest to make it a full size single level house with multiple rooms.

I'd like to see this too. When SE first talked about the private island in SoA, i thought it was going to partially be an expansion of the MH. But, they said there wouldn't be a MH on the island.

In order for a physical expansion of the MH, they would first have to address furniture taking up space in the safe. As is, most people don't have the inventory to make their MH look nice because they have too much gear. It's a matter of worth; the worth of the extra inventory trumps the aesthetic worth of a nicer looking MH.
