Those are my boys!

Thor, Milo and "Goldie."
Goldie hasn't found a permanent name yet. He's also the one with the aggression [towards Thor in particular.]
They are in a store bought cage right now. It's about 24x40, and yes I know! It's not big enough for three grown pigs! Right now, they're so small I'm not so concerned, but I AM looking at C&C equipment. Especially now, I just gave them a huge oatmeal container and they went NUTS over it. Popcorning every where

I'd love for them to have that sort of enjoyment in nice big cage.
Here's my dilemma though
I have two Jack Russell Terriers who roam freely around the house. Although the living room is spacious, my parents won't like the cage in there, and the floor obviously, isn't a good place for it with the dogs. My room doesn't have the floor space, or room for a piece of furniture to put a C&C on. We do however have a guestroom, and my mom and I said we'd love to get a murphy-bed in there, to free up some room, so hopefully we'll get some space in their, and could put up a baby-gate to keep the dogs out, but not isolate the pigs.
My mom and I have blocked the end of the hall for now, to let them have floor time. It would be the equivalent of a 3x12 or longer C&C.
Does anyone have suggestions for more space-savvy C&C?
