They built a corridor extension for this seasonYeah, ultimately they have to deal with the fact that there's just the one set and the corridor only curves one way. Same thing with the quarters we've seen - while the guest quarters from the end of Season 1 (and Shenzhou captain quarters) have the door on the opposite side of the windows, the others we've seen all have them on the perpendicular wall. This leaves people walking past out into space. Maybe the best option there is that some quarters just have fake windows.
