Can I not renovate one into another over a few weeks?

Unlikely. I strongly suspect you don't actually understand anything about physical construction given your seeming belief that all housing units are fungible. So I'll simply state it for you clear and plain: they are not in fact all fungible.

And it's not their fault if only enough housing is being allowed that they can get away with making luxury only housing.

Ah, it's the evil gubmint's fault. Well, that explains a lot.

Did you read what I said enough to make a counterpoint with new information or thinking? Care to be wrong about other things?
