Heinlein was full of contradictions. Look at the built-in furniture: there's no way to change it if you discover it doesn't work for you, other than by ripping it out and redoing the walls. That's not modular or replaceable. The rolling table between the kitchen and dining room is unnecessary for one person, great for two, and inconveniently small for four. And yes, Heinlein designed it. The two volume biography by Patterson is completely uncritical and at times fanboyish, but it seems to have the facts straight.
