Wealthy? That's rather common here, it is not a luxury building

Nice detailwork, but you have to change the granite floor, too. It's way too posh European style for an American apartment house.

Your problem, that you are living in such wealthy circumstances.

It is actually the door of my apartment

Well it looks too new to be exempt from the ADA which requires 12 inches or 30.5 cm clear adjacent to the door opening on the push side of a door.

The door looks too much like a business door in an office building. An apartment door would have more than one lock, one on the knob plus a deadbolt. Also a knocker, peephole, and the apartment number, either on the door or on the wall next to the door. As far as the boxes, the fire extinguisher would in a box with a glass door or mounted directly on the wall, per fire codes it must be accessible and visible.

Mmhhh, the size of the tiles is not a big criterion. Nowadays the variety is bigger and you don't always get only the sizes, which are just fashionable.
The quality of the laying and the usage of the detail-parts is more important.

Indeed, ingo. Did you notice the floor tiles are 30x30cm (or 40x40)! Either way not a US size!!

Pffhhh, if you think so... For me one of the many reasons to switch off a movie, when they appear incorrect.

Well that's acceptable detail The question was more for the very big red box, to be sure that it is not too out of place
