The hallway is no problem. It could just have another 45 in it right behind the kitchen wall. It'd be unorthodox, but I have definitely seen wonkier shit in old apartment buildings. The real problem with it is that it's not depicted with such a bend at the end of it in the episodes where we do see down the length of the hall.

But I'm pretty sure the location of the bedroom as depicted to the right of the bathroom and where the bicycle hangs (right?) is also physically impossible. All the floor plan mockups I've seen place the bedroom to the left, but I'm pretty sure in the show it was depicted as being on the right.

Easily explained. Jerry's apartment exists in a 4 dimensional hypercube. This is clearly shown in the show's intro when watching the show in 4 dimensions.

Apartments in New York are non-euclidean as per regulation.

This is on right now, but of course they are in the diner

Why not? I'm not sure why it shows the cabinets going through the wall, but if it were a straight wall couldn't the hallway just change angle at that point?

I wonder what show has put the most effort into having a plausible layout for all the various rooms. I'd imagine a show set on a ship (space or sea) probably has to have a layout that makes sense to people. But, maybe a show like The West Wing would do it, because people are so familiar with many of those actual rooms.

There’s something you didn’t account for… levels.

Jerry's appt exists in an alternate dimension. His door is a portal. The hallway doesn't exist.

I do trust that you'll post this over at the Seinfeld community. Been a bit of a lull, not that I've done anything to help, but still. Also just discovered this place. What's the deal with this community?

Tardis hallway?

Oh. Oh no. No no no no.

Topology is destiny.
