[But that...is a good idea. It's something he hadn't really considered but he's nodding slowly.] It's possible. The huts are already pretty close together, so it wouldn't be hard to fuse them. But I'm not sure if they would be side by side or just building upward. And size doesn't seem to be an issue now but it may be later? I don't know. [But he seems fixated now.] But that is something that could definitely be tested later.
