I'll chime in.
Overhauled + fixed would be a good way to go, but it would definitely need some improvement. The way it is now, or at least the way it seems to me now, is that the seams suddenly disappear into thin air, while the floor clearly is constructed with metal panels. You'd need huge equipment to build a metal panel big enough to form the whole room (apartment)... and I'm not sure that would even be reasonable (though that can be argued over, I'm sure... it's a space station after all, so, less seams may cause less stress to the structure - or more; I don't quite know the physics there).
What I'm trying to say, I suppose, is that currently it looks like there's some seams in the floor that seem to serve no purpose, as they don't define a panel (they just look like someone would have decided to draw lines to the floor).
I hope I got it typed at least almost right... my keyboard seems to like eating letters today.
