Is the bridge at a funny angle?

Well, they did make it more difficult on themselves because the reno could not change the front elevation of the house (beyond making it match the look from the show.) It was cool watching them do it though.

 

Apparently the corridor and the kitchen exist in parallel dimensions.

 

Yes, I've seen that recently.

One show where the interiors absolutely fit into the exteriors: The police headquarters on Homicide: Life on the Street. The show was shot entirely on location in Baltimore and the producers used an old dance hall on the waterfront for their sets, so every bit of police HQ that you saw was a real building.

Scrubs did something similar, shooting in a closed-down hospital. Even sets like the characters' individual apartments were built inside old hospital rooms. They even had their writers and production offices on the upper floors. They used a different hospital for exterior shots in the early episodes, though, mostly recycled from the pilot.

 

Frasier's apartment steadily grew over the course of that series until logically, it must've occupied most of the floor:

The Cunningham home from "Happy Days" had a similar alignment for its "front" door, but that can be attributed to the needs of recording "before a live studio audience".

That's the beauty of the TARDIS. If it appears hallways and rooms superimpose each other, the in narrative explanation of being dimensionally transcendental solves that issue with nary a drop of sweat.

 

Most sitcoms had their set design "unfolded" for the sake of the live studio audience, going back to "I Love Lucy" and "The Honeymooners". The closest any of them came, at least as far as I could tell, was the "All In The Family" set. The front room sprawled, with separate spaces for the piano and the dining table, but the rest of it made some level of sense. I remember realizing that the kitchen on "Charles In Charge" was actually beside the front entrance rather than around the corner from it some years ago, and having this epiphany moment that they were all that way.

 

By the time Irwin Allen's Land of the Giants' began production, it was decided that the Spindrift's exterior house the actual interior used for shooting, since the unseen port side was open (read: incomplete). Designed by series art director Rodger E. Maus, the ship was 60 feet long and from cast and crew accounts, very hot to shoot in, but for the illusion of a then-futuristic ship, having the ship as "real" as possible did help the actors move as if it was the real deal.

 

The upper deck of the Jupiter 2 was the same. (The lower deck was on a different stage. They also had a separate cockpit-only set for some specific shots.)

 

The Spindrift did have a TARDIS room or two though. When they went through those two doors in the rear wall it led to some engineering and equipment rooms which would not fit in the aft section of the hull...

 

"Excuse me, Stewardess, but where's the bathroom?"

 

To the left rear of the passenger cabin.

 

In the pilot, the engine room is seen, which was accessed through one of the two passenger cabin doors, so that was built into the ship. By the second season, the engineering section had components added, but again, as originally built, the interior had its intended rooms represented.

 

Irwin Allen's sets used a lot of props from his previous shows and movies.
He probably simply used the Fantastic Voyage technology to make the ships fit together....

 

Another impossible space was the back room of the Delta Flyer, especially the stasis pod that retracted into a side wall (which should have had it sticking out into space!)

I never thought of that, though I have to say I love Frasier's apartment.

 

And that's not even getting into the question of how the house rearranged itself when Happy Days went from a single camera on film to a three camera one recorded live before a studio audience. The same thing happened with The Odd Couple. The characters never moved into a new apartment, but the layout of rooms for the apartment set was suddenly different.

 

My big laugh was when I saw deckplans of the Millennium Falcon.
The "Freighter" doesn't have any cargo holds. The most room for cargo is in those smuggling compartments under the floor! To justify this, they say the cargo is held externally and pushed by the jaws of the ships nose. But that's a "Tug boat" not a "Freighter!"

 

Although it does lend to the idea that when Han dumped his cargo, he literally just dropped his cargo and lit out. That said, plenty of freighters use that method. Most massive cargo ships stack their cargo on top of the deck, like so:

 

Not exactly. It's containers on top of containers:
Empty container ship

(technically there are cargo hatches that watertight the holds)
