3x3?

So I'm planning on building a new cage for my 3 boars so they have more room to run around but the only thing i really have room for is something like a 3x3 with maybe a loft because this room is a lot smaller than I thought it would be once I got my bed, dresser, desk, etc in it. I have to keep my pigs in my room because I don't think my roommates would want them in our "community" basement, nor do I really trust them down there without my supervision! haha. Is 3x3 enough space for 3 pigs to run around in for now? I don't know what else to do!! :sad: I love my piggies and I don't want to give them up because I just got them, so I hope there's something I can do!
