In the first few episodes of TNG, the corridor to the left (from the point-of-view of facing the warp core) was open to the rest of the set.
Trekcore has a set photo here showing the corridor open.
A change was made in the middle of "Where No One Has Gone Before".
Here's a screencap from early in the episode, when you can see the corridor to the left is still open:
Here's one from later in the episode, when a console is added, similar to the one on the other side of the room, blocking the corridor:
The console would remain for the rest of the series (if I'm not mistaken), only being removed when the engineering set was emptied to double as large corridor junction.
Does anyone know why the change was made? Why did they put that console there?
It's also notable that at some point (I don't know when?) the console on the right side was replaced with another door, as can be seen in this picture:
