LUTHOR: This is wrong. I wanted the doors off the master side balcony to be sliders. French doors make the room look smaller.

LOIS: Lex, the master bedroom is three thousand square feet. That's more than twice the size of my apartment.

LUTHOR: Well, what about the exercise area? Should we put it back on the ground floor?

LOIS: No, I think this is right. It'll be great to get out of bed and have that stair climber staring me right in the face saying 'Now, Lois. Now.'
And there's a screenshot of the blue prints. We can't see the details, but it's giant:
