About this image

Unique hallway design, made entirely with vanilla assets mashed together.

Specifically, I used a lot of the "Bay" pieces, which are pretty much just the Utility Pit pieces conveniently chopped up in to numerous different configurations. The added definition to the walls comes from the "retaining wall" set, and are actually door frames.

Hotel Pipes along the left hand wall add some tasteful asymmetry.

The floor and ceiling tiles are also independent pieces, so there's also an atypical level of scale to the room.
